INSPECTION PROCEDURE 2: Speedometer does not work (the other meters work). <R.H. drive vehicles for Hong Kong spec.>
TECHNICAL DESCRIPTION (COMMENT) The engine-A/T-ECU and its associated components, the combination meter assembly, the wiring harness, or the connector(s) may be defective.
TROUBLESHOOTING HINTS Malfunction of the engine-A/T-ECU Malfunction of the combination meter assembly The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector.
| DIAGNOSIS PROCEDURE
| STEP 1. Check the speedometer. Connect the MUT-II/III to the diagnosis connector. Use the MUT-II/III to enter simulated vehicle speed. Q: Does the speedometer show that simulated vehicle speed? YES: Go to Step 5. NO: Go to Step 2.
| STEP 2. Connector check: Combination meter connector C-04 and diagnosis connector C-24 for damage. Q: Is combination meter connector C-04 and diagnosis connector C-24 in good condition? YES: Go to Step 3. NO: Repair or replace the damage component(s).
| STEP 3. Check the wiring harness between combination meter connector C-04 (terminal 46) and diagnosis connector C-24 (terminal 14). NOTE: Prior to the wiring harness inspection, joint connector (3) C-02, and repair if necessary. Q: Is the wiring harness between combination meter connector C-04 (terminal 46) and diagnosis connector C-24 (terminal 14) in good condition? YES: Go to Step 4. NO: Repair or replace the damage component(s).
| STEP 4. Retest the system. Q: Is the fuel speedometer normal? YES: The procedure is complete. (If malfunctions are found in all steps, an intermittent malfunction is suspected. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ). NO: Replace the combination meter assembly.
| STEP 5. MUT-II/III diagnosis code Q: Is the MPI-related diagnosis code set? Code No.P0500 is set: GROUP 13A - Troubleshooting or GROUP 13C - Troubleshooting . NO: Go to Step 6.
| STEP6. Connector check: Joint connector C-02 and engine-A/T-ECU connector C-110 <2000> or C-136 <2400-MIVEC>. Q: Is joint connector C-02 and engine-A/T-ECU connector C-110 <2000> or C-136 <2400-MIVEC> in good condition? YES: Go to Step 7. NO: Repair or replace the damage component(s).
| STEP 7. Check the wiring harness between joint connector (3) C-02 (terminal 12) and engine-A/T-ECU connector C-110 (terminal 80) <2000> or C-136 (terminal 79) <2400-MIVEC>. NOTE: Prior to the wiring harness inspection, check intermediate connectors C-105, and repair if necessary. Q: Is the wiring harness between joint connector (3) C-02 (terminal 12) and engine-A/T-ECU connector C-110 (terminal 80) <2000> or C-136 (terminal 79) <2400-MIVEC> in good condition? YES: Go to Step 8. NO: Repair or replace the damage component(s).
| STEP 8. 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 Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ). NO: Go to Step 9.
| STEP 9. Pulse check Use the MUT-II/III or a voltmeter to check that the vehicle speed signal is received. NOTE: Drive the vehicle with the MUT-II/III connected to the diagnosis connector. The MUT-II/III buzzer should sound.
System switch | Check conditions
--- | ---
Vehicle speed signal | When the vehicle speed has reached 10 km/h or more
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? YES: Replace the combination meter assembly. NO: Replace the engine-A/T-ECU.
