Circuit/System Verification

Verify that DTC B1015 is not set.

If the DTC is set, program the rear object sensor control module. If the DTC resets, replace the rear object sensor control module.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptor

DTC B1016 00

- Vehicle Identification Number (VIN) Information Not Programmed

Circuit/System Description

After a loss of battery power has been restored, the remote control door lock receiver (RCDLR) will perform a check on the stored vehicle

identification number (VIN). If the VIN is CORRECT, the RCDLR will run the VIN Timer for a programmable length of time, typically 10

minutes. The RCDLR will send a message via the serial data circuit to the instrument panel cluster (IPC) to illuminate the SECURITY indicator.

After the VIN Timer has timed out, the security indicator will turn OFF. If the VIN is INCORRECT, the RCDLR will send the fuel disable

password to the engine control module (ECM), via the serial data circuit. The immobilizer system considers this to be a tamper and will not allow

the vehicle to start. The RCDLR will send a message via the serial data circuit to the IPC to flash the SECURITY indicator.
