STEP 5. Retest the system.
Q: Is the speedometer normal?
YES :
The procedure is complete. (If no
malfunctions are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00 / How to Cope with
Intermittent Malfunction ).
NO :
Replace the combination meter assembly.
Inspection Procedure 6: Tachometer does not work (Other meters work).
COMMENTS ON TROUBLE SYMPTOM
If only the tachometer does not operate, the engine-
ECU system may not be sending ignition signal, or
the combination meter, the wiring harness or its con-
nector may be defective.
PROBABLE CAUSES
• Malfunction of combination meter
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III other system diagnosis code
Check whether the DIESEL system-related diagno-
sis code is set.
Q: Is the diagnosis code set?
YES :
Diagnose DIESEL system. (Refer to
GROUP 13A, Troubleshooting .) After
diagnosing the DIESEL system, go to Step
4.
NO :
