Faulty Signal. Intermittent Fault

Faulty signal. Intermittent fault

Checking the wiring








- Ignition off
- Disconnect the battery negative lead
- Disconnect the side impact sensor connector
- Disconnect the SRS control module connector
- Connect the battery negative lead.

Warning! There must not be anyone inside the passenger compartment when the battery is connected.

Check the connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Measure the resistance between the side impact sensor:
- terminal #1 and control module terminal #57 (#32)
- terminal #2 and control module terminal #58 (#33).
check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
The resistance must be approximately 0 ohms. If not there is an open-circuit.
Measure the resistance between control module terminal #57 (#32) and chassis ground. Measure the resistance between side impact sensor terminal #1 and chassis ground. Check for an intermittent short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
The resistance must be infinite.
Measure the resistance between control module terminal #57 (#32) and chassis ground. Measure the resistance between side impact sensor terminal #1 and chassis ground. Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
The voltage must be 0 V. If not there is a short-circuit to supply voltage.
Remedy as necessary.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
