Signal Too High. Intermittent Fault

Signal too high. Intermittent fault

Checking the cable












- Ignition off
- Disconnect the battery negative lead
- Disconnect the SRS control module.
- Disconnect the connector for the seat belt tensioner.

Warning! Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected, non-deployed, pyrotechnical airbag. This could deploy the airbag!

Caution! Do not touch the terminal pins in the SRS control module. There is a risk of static discharge which could damage the control module.

Check the connectors for:
- the SRS control module
- the seat belt tensioner.
check for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Measure the voltage between SRS control module:
- terminal #31 (#6) and chassis ground
- terminal #32 (#7) and chassis ground.
Check between the igniter connector:
- terminal #1 and chassis ground
- terminal #3 and chassis ground.
for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
There is a short-circuit to supply voltage if the voltage is greater than 0 V.
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).
