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

E1 - E2:






E3 - E4:






E5 - E7:






Normal Operation
The Restraints Control Module (RCM) monitors the electrical condition at C31OA pins 10, 13 and 14 to determine if it is installed on the correct vehicle. If the RCM detects an unexpected condition on any of these pins, it will store a Diagnostic Trouble Code (DTC) C1414 in memory and flash a Lamp Fault Code (LFC) 29 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
An incorrect vehicle ID code can be caused by:
^ an RCM installed on the wrong vehicle.
^ an incorrectly programmed RCM.
^ vehicle ID pins (RCM C310A pins 10, 13 and 14) not connected as expected.
