ELECTRICAL TROUBLESHOOTING MANUAL
TROUBLESHOOTING HINTS
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). If the Brake Warning Light does not
operate at all, check Instrument Cluster (Z142) and
K Wire.
SYSTEM DIAGNOSIS
15. If the Charge Warning Light does not operate,
go to Section B1.
16. If the Oil Pressure Warning Light remains
illuminated with the oil pressure OK, do Test A.
17. If the Malfunction Indicator Lamp (Check
Engine) does not operate, do Test B for
MFI±V8 engines, Test C for 300TDI with EDC
engines.
18. If the Glow Plug Indictor does not operate, do
Test D.
19. If the Brake Warning Light does not operate
with the Brake Fluid Level low, do Test E.
20. If the Brake Warning Light does not operate
with the Handbrake applied, do Test F.
21. If the Differential Lock Indicator remains on
after the differential lock has been disengaged,
transmission ªwind upº 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.
22. If the Fasten Seat Belt Indicator does not
operate with the ignition on, do Test H.
23. If the Transmission/Transfer Box Oil
Temperature Warning Light is illuminated with
both the Transfer Box Oil Temperature and the
Automatic Transmission Oil Temperature OK,
do Test I.
24. If a warning light exhibits any symptom not
mentioned above, check the associated bulb,
wires, switches, and components.
