ECM LOCATION AND REMOVAL

Please Note: Removing and Installating your truck's ECM is VERY SIMPLE. The ECM is attached to the drivers's side battery tray and its does not take but a few minutes to replace without special tools. The ECM is encased in a steel housing and we promise you that you won't damage it in the process!!!

 

The ECM is located on the bottom side of the Main Battery tray Drivers Side(towards firewall).

For the LB7 (01-04)remove the black plastic pouch cover and remove the 2 metal clips. Use a 7mm socket to losen the bolts on the wireharness plug and remove the plug from the ECM.

For the LLY (04.5-05) pop the top off the pouch and unlatch the 3 wireharness plugs. The ECM will then slide of of the pouch.

For the LBZ and LMM just unlatch the 2 wireharness plugs and remove the ECM. There is NO plastic cover.

      01-04 LB7             04.5-05 LLY          06-08 LLY/LBZ/LMM

MAKE SURE THE MODULE DOES NOT SAY "ALLISON" (because the module on the radiator belongs to the Allison transmission and not the engine)
 
 
 
Passkey Security Relearn Procedure: (Pre-Tuned ECMs ONLY)

IF YOU ARE INSTALLING AN ECM WE FURNISHED THEN YOU MUST FOLLOW THIS PROCEDURE ONCE INSTALLED TO START THE VEHICLE: (this is not applicable with your truck's ECM)

1. Disable your headlamps. Attempt to start the vehicle. Vehicle may or may not 'fire' and quit. Some vehicles will not engage the starter. This is normal. DO NOT TURN OFF KEY YET !!

2. Leave the key in the "on" position, until the 'security' light goes out or quits alternately flashing between "Security" and "Battery". This relearn period always takes 10 minutes. How long does this take? 10 minutes. How long do I have to wait? 10 minutes.

3. After security light is no longer displayed, shut the key off! Wait 5-10 seconds and repeat the above procedure (steps 1 through 3) another two completed times for a total of 3 start-relearn-attempts, remembering to shut the key off between each 10 minute relearn procedure. THIS WILL TAKE 30 MINUTES--NO LESS. If the 4th start attempt fails to start the vehicle you did one relearn step (or all of them incorrectly). If you left your headlamps on until the battery went dead and voltage dropped below 10.5 volts, no amount of relearn attempts will be learned!!

Don't read too much into this. Most people overlook the simplicity of this relearn procedure.
