ECM PCM BRAINBOX ECU ECC BCM MAIN BRAIN
WHAT IS MY CAR OR TRUCK COMPUTER CALLED AND WHICH ONE(S) DO I NEED TO TEST OR REPAIR OR REPLACE??
There is controversy over the terminology of the electronic control computers designed and implemented for electronic functionality within a vehicle like lights and blinkers and your wipers and lets wrap our head around the fact that engine control management and transmission control management is all controlled by on-board computers as well. For over two decades we have heard, "It is an ECU or an ECM? What is a PCM a BCM or a GEM?"
ECMtoGo.com has been specializing in Test & Repair, Programming & Replacement of ECM PCM computer controllers online since 1997. We have comprised the most knowledgeable team for servicing these highly technical, extremely sensitive and often very expensive vital components to your vehicle. These Computers control and initiate operation, engine performance, fuel regulation and optimization and of course carbon emission monitoring and control, and engine management diagnostics. Now we are here to help educate you not only in terminology, but the reason you may be in this position (or perhaps you're not in the position after all, if we test it and it tests good) and the best way to get out of it (ECM Repair Service or PCM Replacement Service) with the least amount of money spent and certainly the least amount of money wasted due to lack of information caused by misdiagnosis or misunderstood terminology!

TERMINOLOGY AND ACRONYMS EXPLAINED
Electronic Control Module ECM Engine Control Unit ECU Powertrain Control Module PCM Engine Control Module ECM Engine Control Unit ECU Electronic Control Computer ECC Body Control Module BCM Vehicle Lighting Control Module VLCM or LCM, General Electronic Module GEM
Today's vehicle are full of computer controllers for engine management & engine diagnostics like Engine Control and Powertrain Control computer ECM PCM, Engine Control Computer ECC, Transmission Control Module TCM, Body Control Module BCM which can refer to several computer controllers in the vehicle (in the vehicle body as well as body controlling functions) such as the Security module BCM, Vehicle Light Control Module, General Electronic Module GEM and Totally Integrated Power Model TIPM which is the front control module and often the Fuse control combined now with added functions and critical operations.
Many of these computers can be considered ECM or ECU meaning they are Electronic Control Modules or Electronic Control Units. Within these references, there can be more strict differentiation, but for the purposes of this instruction source, let's just keep it somewhat simple. ECM and ECU is also an acronym for Engine Control Module and Engine Control Unit. On vehicles with manual transmission, there is no control unit necessary. On these models, the engine management system uses an ECM. Some models used a separate Transmission Control Module TCM that is linked with the ECM to control the automatic trans axle shift points. Many vehicles with automatic transmission have the Transmission Control Module TCM and Engine Control Module ECM integrated into a single Computer Control Module unit, called the Powertrain Control Module PCM. The ECM or PCM processes input from various sensors, compares the input with pre-programmed information and sends output signals to control the fuel supply, ignition timing, actuators such as the Idle Air Control IAC and the engine emission system. The PCM also controls the shift functions on automatic transmission models. And all the while the main computer ECM or PCM is also a diagnostic tool for accumulated and real time diagnostics and performance assurance.

GM VEHICLE THEFT DETERRENT (VTD) RELEARN PROCEDURES
GM vehicles have three types of Vehicle Thief Deterrent (VTD) systems, each requiring their own set of relearn procedures. Unless these procedures are correctly performed the vehicle will not start after the PCM has been replaced. The three systems are: Vehicle Anti-Theft System (VATS), Passkey, & Passkey II â€“ resistive chip ignition key Passlock â€“ coded lock cylinder Passkey III â€“ transponder ignition key How do you know what system your vehicle has? Just look at the keys (see info below).
The sections that follow will help you identify the system and describe how to do the relearn required for your application.
VATS, Passkey, & Passkey II â€“ resistive chip ignition key
Vehicle Anti-Theft System (VATS) â€“ VATS has a separate module called the Theft Deterrent Module (TDM) that validates the resistive chip in the ignition key. If the resistance value read by the TDM is what the TDM is expecting, the TDM will send a signal to the PCM informing the PCM that a valid key is present and the PCM may start the vehicle. No relearn is required on a VATS equipped vehicle when replacing the PCM. Passkey â€“ The Passkey system has a separate module called the Theft Deterrent Module (TDM) that validates the resistive chip in the ignition key. If the resistance value read by the TDM is what the TDM is expecting, the TDM will send a signal to the PCM informing the PCM that a valid key is present and the PCM may start the vehicle. No relearn is required on a Passkey equipped vehicle when replacing the PCM. Passkey II â€“ The Passkey II system has the Theft Deterrent Module (TDM) function stored in the Body Control Module (BCM). The TDM portion of the BCM will validate the resistive chip in the ignition key. If resistance value read by the BCM is what the BCM is expecting, the BCM will send a message over serial data to the PCM informing the PCM that a valid key is present and the PCM may start the vehicle. To perform a relearn on a Passkey II system, make sure there is a fully charged battery in the vehicle. The battery will be used for 30 minutes without the alternator available for charging. Connect a battery charger to the battery to ensure power is available while programming. Both the BCM and PCM must be working and communicating with each other.
1. Insert ignition key and turn to the â€śONâ€ť position. Do not attempt to start the engine. Leave the key in the â€śONâ€ť position for approximately 11 minutes. The security light will be steady on or flashing for the 11-minute period. Do not proceed to Step 2 until the security light turns off or stops flashing.
2.Turn the ignition switch to the â€śOFFâ€ť position for 30 seconds.
3.Turn the ignition switch to the â€śONâ€ť position as in Step 1 for 11 minutes.
4. Turn the ignition switch to the â€śOFFâ€ť position for 30 seconds.
5. Turn the ignition switch to the â€śONâ€ť position as in Step 1 for 11 minutes for a third time.
6. Turn the ignition switch to the â€śOFFâ€ť position for 30 seconds for a third time.
7. Turn the ignition switch to the â€śONâ€ť position for 30 seconds.
8. Turn the ignition switch to the â€śOFFâ€ť position.
9. Attempt to start the engine. If the engine starts and runs, the relearn is complete.
Passlock â€“ coded lock cylinder
The Passlock anti-theft system requires the presence of a key in the lock cylinder to enable starting. The lock cylinder contains a stationary Hall effect sensor and a rotating magnet. When the key is turned in the lock cylinder, the magnet creates a signal on the Hall effect sensor. The cylinder then sends a coded signal to the instrument panel cluster (IPC) or body control module BCM. If the IPC/BCM receives the expected coded signal, the IPC/BCM will send a message over serial data to inform the PCM that the vehicle may be started. To perform a relearn on a Passlock system, make sure there is a fully charged battery in the vehicle. The battery will be used for 30 minutes without the alternator available for charging.
Connect a battery charger to the battery to ensure power is available while programming. Both the IPC/BCM and PCM must be working and communicating with each other.
1. Turn ignition on.
2. Attempt to start the engine, and then release the key to the â€śONâ€ť position.
3. Observe the â€śSECURITYâ€ť indicator light. After 10 minutes the â€śSECURITYâ€ť indicator light will turn off.
4. Turn ignition to the â€śOFFâ€ť position, and wait 10 seconds.
5. Attempt to start the engine, and then release the key to the â€śONâ€ť position.
6. Observe the â€śSECURITYâ€ť indicator light. After 10 minutes the â€śSECURITYâ€ť indicator light will turn off.
7. Turn ignition to the â€śOFFâ€ť position, and wait 10 seconds.
8. Attempt to start the engine, and then release the key to the â€śONâ€ť position.
9. Observe the â€śSECURITYâ€ť indicator light. After 10 minutes the â€śSECURITYâ€ť indicator light will turn off.
10. Turn ignition to the â€śOFFâ€ť position, and wait 10 seconds.
11. Vehicle has now learned the new password. Start the engine.
12. With a scan tool, clear any trouble codes. NOTE: For most cars, one 10-minute cycle will be enough for the vehicle to learn the new password. Perform all 3 cycles if the car will not start after 1 cycle. Most trucks will require all 3 cycles for learning the password.
Passkey III â€“ transponder ignition key
The Passkey III anti-theft system uses a transponder inside the head of the ignition key. The exciter inside the ignition lock cylinder energizes this transponder when the ignition switch is turned on. The transponder transmits a unique signature to the theft deterrent control module. If the key signature transmitted is acceptable to the theft deterrent control module, the theft deterrent control module will transmit fuel enable password to the PCM. If the fuel enable password is correct, the PCM will start the vehicle. To perform a relearn on a Passkey III system, make sure there is a fully charged battery in the vehicle. The battery will be used for 30 minutes without the alternator available for charging. Connect a battery charger to the battery to ensure power is available while programming. When performing this relearn, all previously learned keys will be erased. Additional keys may be relearned immediately after the first key has been learned by inserting the additional key and turning the ignition switch to on within 10 seconds of removing the previously learned key.
1. Insert a master key (black head) into the ignition switch.
2. Turn key to the â€śONâ€ť position without starting the engine. Security light should turn on and stay on.
3. Wait for 10 minutes or until the security light turns off.
4. Turn key to the â€śOFFâ€ť position for 5 seconds.
5. Turn key to the â€śONâ€ť position without starting the engine. Security light should turn on and stay on.
6. Wait for 10 minutes or until the security light turns off.
7. Turn key to the â€śOFFâ€ť position for 5 seconds.
8. Turn key to the â€śONâ€ť position without starting the engine. Security light should turn on and stay on.
9. Wait for 10 minutes or until the security light turns off.
10. Turn key to the â€śOFFâ€ť position. The key transponder information will be learned on the next start cycle.
11. Start the vehicle. If the vehicle starts and runs normally, the relearn is complete. If additional keys need to be relearned:
12. Turn the key to the â€śOFFâ€ť position.
13. Insert the next key to be learned. Turn the key to the â€śONâ€ť position within 10 seconds of removing the previously used key.
14. Wait for security light to turn off. It should happen fairly quickly. You may not notice the lamp, as the transponder value will be learned immediately
15. Repeat steps 12 through 14 for any additional keys.
