PINPOINT TEST 2: DTC B1118 - PASSENGER FRONT CRASH SENSOR MOUNT/COMMUNICATION FAULT
Normal OperationThe restraints control module (RCM) checks all of the RH front impact severity sensor circuits for faults. If the RCM detects one of the following faults on any of the impact sensor circuits, it will store DTC B1118 in memory and illuminate the air bag warning indicator. When the RCM is unable to communicate with the passenger front impact sensor, the RCM sets DTC B1118 Passenger Front Crash Sensor Mount/Communication Fault.
This pinpoint is intended to diagnose the following:
- Wiring, terminals or connectors
- RH front impact severity sensor
- Incorrect sensor mounting
- RCM
WARNING:Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a crash and possibly violate vehicle safety standards.
CAUTION:Use the correct probe adapter(s) when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE:Supplemental restraint system (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE:Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
