Test B: DTC B1342 - ECU (OCSM) Is Faulted
PINPOINT TEST B: DTC B1342 - ECU (OCSM) IS FAULTEDNormal Operation
The occupant classification sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact.
The occupant classification system module (OCSM) monitors internal circuity, hardware and the 4 OCS weight sensor bolts and external circuitry for faults. If the OCSM detects a fault with the internal circuitry, internal hardware, sensor(s) or external circuitry, it will store DTC B1342 in memory and send a message to the restraints control module (RCM). A short to ground on any one of the sensor reference voltage circuits or an open on 3 or more of the sensor reference voltage circuits may set this DTC. The RCM will store DTC B2290 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Incorrectly wired OCS weight sensors
- OCS system component
