Signal Too High

Signal too high

Checking components and wiring








- Switch off the ignition. Wait 10 seconds
- Disconnect the connector from the front right-hand front impact sensor
- Disconnect the connectors from the supplemental restraint system module (SRS).

Caution! Do not touch the terminal pins in the supplemental restraint system module (SRS). There is a risk of static discharge. This could damage the supplemental restraint system module (SRS).

Check the connectors to the front impact sensor and the supplemental restraint system module (SRS). Check for damage to pins and terminals in the connectors. Also check the other connectors that connect the signal cable between the supplemental restraint system module (SRS) and the front impact sensor.
Remedy as necessary.
Check the cable between the supplemental restraint system module (SRS) and the front impact sensor connector. Check for a short-circuit to supply voltage.
Check the cable between:
- Supplemental restraint system module (SRS) terminal #B5 and front impact sensor connector terminal #1
- Supplemental restraint system module (SRS) terminal #B9 and front impact sensor connector terminal #2.
Remedy as necessary.
