Test G: LFC 53/DTC B1892 - Air Bag Tone Warning Indicator Circuit Short to Ground or Open
PINPOINT TEST G: LFC 53/DTC B1892 - AIR BAG TONE WARNING INDICATOR CIRCUIT SHORT TO GROUND OR OPENNormal 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 C310a pin 22.
If the RCM detects a short to ground or open on the connection to the cluster, it will store DTC B1892 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 Open or Short to Ground - If the RCM detects an open circuit or short to ground when the indicator is not active, it will set this DTC.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- IC module
- RCM
