Faulty Signal. Permanent Fault
Faulty signal. Permanent fault
Function test
Check that the ROPS indicator lamp lights.
Does the lamp light?
Yes - Checking connector and cable
No - Checking component and cables
-------------------------------------------------
Checking connector and cable
- Ignition off.
- Disconnect the control module connector.
- Check the control module terminal pins visually without touching them.
Check that the plastic rail in connectors 24 and 25 are undamaged. The plastic rail prevents the ROPS warning lamp from being short-circuited to ground when the control module is connected.
Replace the control module if the plastic rail is damaged.
- Disconnect the ground terminal which is located next to the control module.
- Ignition on.
If the ROPS indicator lamp does not light, the fault is in the connector. Replace the connector.

- To disconnect/replace control module, see Replacing the Roll-over Protection System (ROPS) module Service and Repair.
Does the ROPS indicator lamp light?
Yes - Checking the combined instrument panel
No - Verification
-------------------------------------------------
Checking the combined instrument panel
- The fault is in the cable or in the combined instrument panel.
- Ignition off.
- Disconnect combined instrument panel connector B.
Check connector B for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Connect an ohmmeter between control module B12 and ground, measure for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
If there is a short-circuit to ground, the cable must be repaired or replaced. Otherwise the fault is in the combined instrument panel.
Remedy as necessary.
Other information:
- To access/replace combined instrument panel, see Combined instrument panel, Removal, replacement.
- To access/replace the control module, see Replacing the Roll-over Protection System (ROPS) module Service and Repair.
Select Continue when the fault has been remedied.
Continue - Verification
-------------------------------------------------
Checking component and cables
- Try a new bulb.
- Check control module connector for contact resistance and oxidation in accordance with Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Disconnect the ground terminal which is located next to the control module.
- Ignition on.
Connect an voltmeter between control module 12 and ground. The voltage should be slightly under battery voltage.
Other information:
- To access/replace the bulb, see Replacing bulb Removal and Replacement.
- To access/replace the control module, see Replacing the Roll-over Protection System (ROPS) module Service and Repair.
Is the voltage slightly under battery voltage?
Yes - Checking ground lead
No - Checking the signal cable
-------------------------------------------------
Checking ground lead
The results of the reading indicate that the cable is intact and that the fault is in the connector or the ground lead.
Check the ground lead 6 on the connector for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Remedy as necessary.
Select Continue when the fault has been remedied.
Continue - Verification
-------------------------------------------------
Checking the signal cable
- The fault is in the cable or in the combined instrument panel.
- Ignition off.
- Disconnect combined instrument panel connector B.
Check the cable between the combined instrument panel connector terminal B15 and control module connector 12 for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
If there is an open-circuit the cable must be replaced or repaired. If there is no open-circuit, the fault is in the combined instrument panel.
Remedy as necessary.
Other information:
- To access/replace combined instrument panel, see Combined instrument panel, Removal, replacement.
Select Continue when the fault has been remedied.
Continue - Verification
-------------------------------------------------
Verification
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
- Reinstall connectors, components etc.
- Ignition on.
- Read off diagnostic trouble codes (DTCs).
If the DTC status changed to intermittent it means that the fault is no longer present.
Does the status change?
Yes - VERIFIED
No - VERIFICATION FAILED
------------------------
VERIFIED - FAULT FOUND
VERIFICATION FAILED - Fault-tracing information
-------------------------------------------------
Fault-tracing information
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
