WARNINGS AND INDICATORS – FAULT DIAGNOSIS

TROUBLESHOOTING HINTS

15. If more than one warning light is out, check power and ground wires common to all affected warning lights. If they are OK, replace Instrument Cluster (Z142). 16. If the Brake Warning Light does not operate at all, check Instrument Cluster (Z142) and K Wire. For Australian vehicles: 17. If the Brake Warning Light, the Catalyst Warning Indicator, and the Transmission Box Oil Temperature Warning Light don’t illuminate, as a bulb test, with the ignition on, replace Instrument Cluster (Z142). If all three indicators don’t turn off with the engine running, replace Instrument Cluster (Z142).

SYSTEM DIAGNOSIS

1. If the Charge Warning Light does not operate, go to Section B1. 2. If the Oil Pressure Warning Light remains illuminated with the oil pressure OK, do Test A. 3. If the Malfunction Indicator Lamp (Check Engine) does not operate, do Test B for MFI-V8 engines, Test C for 300TDI with EDC engines. 4. If the Glow Plug Indicator does not operate, do Test D. 5. If the Brake Warning Light does not operate with the brake fluid level low, do Test E. 6. If the Brake Warning Light does not operate with the handbrake applied, do Test F. 7. If the Differential Lock Indicator remains on after the differential lock has been disengaged, transmission “wind up” may be present. Drive the vehicle in reverse for a short distance, then drive forward for a short distance. If the light remains on after driving in reverse, do Test G. 8. If the Fasten Seat Belt Indicator does not operate with the ignition on, do Test H. 9. If the Transmission/Transfer Box Oil Temperature Warning Light is illuminated with both the Transfer Box Oil Temperature and the Automatic Oil Temperature OK, do Test I. 10. If a warning light exhibits any symptom not mentioned above, check the associated bulb, wires, switches, and components.
