Signal missing. Intermittent fault

Checking component

Caution! SRS-312 is stored if a fault occurs in the left front seat belt tensioner or the left rear seat belt tensioner. It may be necessary to carry out fault-tracing on the front and rear seat belt tensioners to find the fault.












- Make a note of the anti-theft radio code.
- Ignition off.
- Disconnect the battery negative lead.
- Disconnect the connector from the left seat belt tensioner, front or rear.

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

- Disconnect the control module.
- Check the control module connector for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check for damage carefully.
Connect an ohmmeter between seat belt tensioner #1 and #2. Check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
