Pinpoint Test C: LFC 29/DTC C1414 — Incorrect Vehicle Identification Code
Normal Operation
The restraints control module (RCM) monitors the electrical state of pins 10, 13 and 14 to determine if
it is installed on the correct vehicle. If the RCM detects an incorrect 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 identification code can be caused by:
an RCM installed on the wrong vehicle.
an incorrectly programmed RCM.
vehicle ID pins not connected as expected.
