Test Z: DTC B1013 - Occupant Classification Calibration Fault
PINPOINT TEST Z: DTC B1013 - OCCUPANT CLASSIFICATION CALIBRATION FAULTNormal 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 the OCS weight sensor bolts for a correct calibration/weight and ID from each sensor. If the OCSM detects an incorrect weight or ID from any of the 4 seat weight sensors, a seat track that is mis-aligned/bent, wire harness connected to the incorrect OCS weight sensor bolt, an unsuccessful system reset or if an OCS system component has been installed new, it will store DTC B1013 in memory and send a message to the restraints control module (RCM) which stores DTC B2290 in memory. The RCM will then 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 of OCS weight sensor bolts
- Wiring, terminals or connectors
- OCS system component installed new
- Passenger seat track
- Misrouted harness
- Seat track mounting and alignment
- Seat track fastener torque
