Faulty signal. Permanent fault
Function test
Check that the ROPS warning lamp lights.
Does the lamp light?
Yes - Checking the connector and cable
No - Checking components and wiring
-------------------------------------------------
Checking the connector and cable
- Ignition off.
- Disconnect the control module connector.
- Check the control module terminal pins visually without touching them.
Check that the plastic strip in connectors 24 and 25 is intact. The plastic strip prevents short-circuits to ground in the ROPS warning lamp when the control module is connected.
Replace the control module if the plastic strip is damaged.
- Disconnect the ground connection positioned beside the control module.
- Ignition on.
The fault is in the connector if the ROPS warning lamp does not light. Replace the connector.

- To disconnect / replace the control module, see Replacing the Roll-over Protection System (ROPS) module Service and Repair.
Does the ROPS warning 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. Check 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 the combined instrument panel, see Combined instrument panel, Removal, replacement 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 components and wiring
- Try a new bulb.
- Check the control module connector for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Disconnect the ground connection positioned beside the control module.
- Ignition on.
Connect a voltmeter between control module 12 and ground. The voltage should be just below battery voltage.
Other information:
- To access / replace the bulb see Replacing bulb Replacing Bulb
- To access / replace the control module, see Replacing the Roll-over Protection System (ROPS) module Service and Repair.
Is the voltage slightly below battery voltage?
Yes - Checking ground lead
No - Checking the signal cable
-------------------------------------------------
Checking ground lead
The reading indicates that the cable is intact and that the fault is in the connector or ground lead.
Check 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 combined instrument panel connector B15 and control module connector 12 for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
The cable must be replaced or repaired if an open circuit is found. The fault is in the combined instrument panel if there is no open-circuit.
Remedy as necessary.
Other information:
- To access / replace the combined instrument panel, see Combined instrument panel, Removal, replacement 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 the 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
