Passive Entry Module

B2205-00-Original VIN Missing/Mismatch

For a complete wiring diagram, refer to.

• When Monitored: During a Passive Entry or Keyless Go event.

• Set Condition: The Passive Entry Module (PEM) will receive and monitor the VIN message from the PCM and record the VIN if different from the last VIN. If the module was used on a previous vehicle, the VIN will be set to that vehicle and the module will have to be replaced.

• Do not attempt to swap PEM modules. If a PEM module has been used on one vehicle, it cannot be used on another vehicle.






Test Step 1 - CHECK THE VEHICLE VIN

• Using the FOBIK, turn the ignition on.

• With the scan tool, select: PEM, "REPORTS", "ECU Details Report".

• Scroll down to "PEM", read the "VIN Original" and compare it to the actual vehicle VIN.

Does the PEM VIN Original match the vehicle VIN?

Yes
