Pinpoint Test - Supplemental Restraint System (SRS)

Pinpoint Test M: DTC B0090:11 or B0090:93

Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. [1][2]Diagrams By Number

Normal Operation
The Restraints Control Module (RCM) checks the LH front impact severity sensor and circuits for the following faults:

- Open circuit
- Short to voltage
- Short to ground
- Faulted LH front impact severity sensor
If a fault is detected, the RCM (Restraints Control Module) will store DTC B0090:11 or B0090:93 in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

- DTC B0090:11 (Left Frontal Restraints Sensor: Circuit Short to Ground)- When the RCM (Restraints Control Module) senses a short to ground on the LH front severity impact sensor feed circuit, a fault will be indicated.
- DTC B0090:93 (Left Frontal Restraints Sensor: No Operation)- When the RCM (Restraints Control Module) senses a faulted sensor, a short to voltage on the feed circuit or an open feed or return circuit, a fault will be indicated.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- LH front impact severity sensor
- RCM (Restraints Control Module)
