Test G: LFC 53/DTC B1892 - Air Bag Tone Warning Indicator Circuit Failure
PINPOINT TEST G: LFC 53/DTC B1892 - AIR BAG TONE WARNING INDICATOR CIRCUIT FAILURENormal Operation
The connection between the instrument cluster (IC) module and restraints control module (RCM) is used to signal a chime if the primary air bag warning indicator is inoperative and another supplemental restraint system (SRS) fault exists. The RCM monitors this connection to the IC module at C220 pin 23.
If the RCM detects a circuit failure on the connection to the IC module, it will store DTC B1891 in memory and flash LFC 53 (or a higher priority code if one exists) on the air bag warning indicator.
- DTC B1892 Air Bag Tone Warning Indicator Circuit Failure - If the RCM detects an open circuit or short to ground on the air bag tone warning indicator circuit, it will set this DTC.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- IC module
- RCM
