STEP 24. Check the harness between shift switch 
assembly connector C-129 <RHD>, C-143 <LHD> 
terminal No.5 and engine-A/T-ECU connector 
C-141 terminal No.68.

Check the output line for short-circuited or open 
circuit.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the wiring harness.

INSPECTION PROCEDURE 17: Abnormal shift indicator display

OPERATION
The engine-A/T-ECU detects the shift range (sport 
mode) which the driver has selected, and sends the 
information to the combination meter.

COMMENTS ON TROUBLE SYMPTOM
The cause is probably a malfunction of the shift 
switch assembly, combination meter and 
engine-A/T-ECU.

Possible causes

•

Malfunction of shift switch assembly

•

Malfunction of the combination meter

•

Damaged harness wires and connectors

•

Malfunction of the engine-A/T-ECU

DIAGNOSIS

STEP 1. MUT-II/III data list

•

Item 67: Select switch

•

Item 68: Upshift switch

•

Item 69: Downshift switch

Check the above data list 

P.23A-133

. (Refer to data 

list reference table.)

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to inspection procedure 16: shift 
switch assembly system 

P.23A-114

.

STEP 2. Measure the voltage at engine-A/T-ECU 
connector C-138.
(1) Confirm the shift range by using the Actuator test 

on the MUT-II/III, and measure the voltage at the 

ENGINE-
A/T-ECU
