Normal Operation
The RCM monitors the communication condition and circuits of the OCS sensor for an embedded vehicle ID. The RCM utilizes C310a pin 21, circuit 1203 (BK/LB) for identifying a regular cab vehicle. If the RCM detects an unexpected condition or code from the OCS system or detects a fault at C310a pin 21, it will store diagnostic trouble code (DTC) C1414 in memory and flash lamp fault code (LFC) 15 (or higher priority code if one exists) on the air bag indicator.

Possible Causes

NOTE: RCM connector C310a pin 21 should be populated with circuit 1203 (BK/LB) for regular cab vehicles only.

An incorrect vehicle identification code can be caused by:
- incorrect RCM for vehicle
- incorrect OCS system for vehicle.
- wiring, terminals or connectors.
