OBDII 6.5L Passlock Security Relearn

To perform a Passlock system relearn, make sure the vehicle battery is fully charged, as it will be used for 30 minutes without the alternator for charging. Connect a battery charger to the battery to ensure steady power while programming. Both the IPC/BCM and PCM must be working and communicating with each other to successfully complete the relearn. Relearn procedure:

1. Turn ignition on.

2. Attempt to start the engine, and then release the key to the ON position.

3. Observe the security indicator light. After 10 minutes, the security indicator light will turn off.

4. Turn ignition to the OFF position, and wait 10 seconds. 2 of 4 3 of 4
