Signal Too High. Permanent Fault

Signal too high. Permanent fault

Checking the cable








- Ignition off.
- Disconnect the 2-pin connector under the right-hand seat.

Warning! Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected non-deployed pyrotechnic 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 SRS control module.

Check the cable between the SRS control unit #4C(60) and the 2-pin connector #1 for short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Check the cable between the SRS control unit #3C(59) and the 2-pin connector #2 for short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.

Other information:
- To access / replace the SRS control module and connector, Service and Repair.
- To connect the breakout box, see Connecting the breakout box Connecting the Breakout Box, Supplemental Restraint System Module (SRS).
- With the ignition off and the 2-pin connector disconnected, the resistance between the 2-pin connector #1, #2 (SRS control module side) and the disconnected battery positive pole should read infinity.
- For information about removing the battery cables, see Battery, disconnecting Battery Disconnecting.
- With the ignition off and the 2-pin connector disconnected, the resistance between the 2-pin connector #1 and #2 (SRS control module side) should be approximately 22 kohms.
- To repair SRS wiring, see Cable harness SRS system, repair Procedures.
- For other values, see Signal specification Signal Description, Supplemental Restraint System (SRS) Control Unit.

Hint: After carrying out the repair, check that the fault has been remedied.




- Ignition off
- Disconnect the battery negative lead
- Reinstall the connectors, components etc.
- Ignition on
- Connect the battery negative lead.

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

- Read off diagnostic trouble codes (DTCs).
The fault is no longer present if the diagnostic trouble code (DTC) status is intermittent.





Is the diagnostic trouble code (DTC) intermittent?

Yes - Verification completed

No - Fault-tracing information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing

No - Attempt New Test
