Test P: LFC 29/DTC C1414 - Incorrect Vehicle Identification Code

P1:






P2:






P3 - P5:






Normal Operation
The Restraints Control Module (RCM) monitors the electrical condition at C310a pins 7 and 8 to detect the vehicle identification code. The RCM compares the pin state with a preprogrammed code. If the RCM detects an unexpected condition at either of these pins, it will store Diagnostic Trouble Code (DTC) C1414 in memory and flash Lamp Fault Code (LFC) 29 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
An incorrect vehicle identification code can be caused by:
^ an RCM installed on the wrong vehicle.
^ an RCM internal fault.
^ a wiring concern at RCM C310a pins 7 or 8.
