STEP 7. Check the wiring harness between joint 
connector C-02 (terminal 25) and engine-ECU 
<2000> connector C-137 (terminal 86) or 
engine-ECU <2400> connector C-141 (terminal 
79).

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connectors C-105, joint connectors 
C-16 <2000> and repair if necessary.

Q: Is the wiring harness between joint connector C-02 

(terminal 25) and engine-ECU <2000> connector 
C-137 (terminal 86) or engine-ECU <2400> 
connector C-141 (terminal 79) 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.

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-ECU.

INSPECTION PROCEDURE 2: Speedometer does not work (the other meters work.)  <A/T>

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 output shaft speed sensor

•

Malfunction of the engine-ECU

•

Malfunction of the combination meter assembly

•

The wiring harness or connectors may have

DIAGNOSIS PROCEDURE 

STEP 1. Check the speedometer.

(1) Connect the MUT-II/III to the diagnosis connector.
(2) 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

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).
