COMMENT ON TROUBLE SYMPTOM

• Failure is possibly caused by failed starter itself 

or failed related circuit.

PROBABLE CAUSES

• Failed battery

• Failed inhibitor switch

• Failed starter motor

• Failed starter relay

• Open/short circuit in starter associated circuit or 

loose connector contact

• Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Check battery voltage.

• Measure battery voltage at cranking.

OK: 8 V or higher

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Check battery (Refer to GROUP 54A 

− 

Battery-On-vehicle Service 

− Battery Test ).

STEP 2. M.U.T.-III data list

• Item 40: Starter switch

OK: 

ON (Ignition switch: ST)
OFF (Ignition switch: ON)

Q: Is the check result normal?

YES : 

Go to Step 17.

NO : 

Go to Step 3.

STEP 3. Connector check: A-16X starter relay 
connector

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair or replace.

STEP 4. Check starter relay

• Check starter relay (Refer to GROUP 16 − Start-

ing System 

− Starter Relay Check ).

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the starter relay.

STEP 5. Perform voltage measurement at A-16X 
starter relay connector.

• Disconnect connector, and measure at the har-

ness side.

• Ignition switch: ST

• Voltage between terminal No. 2 and earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 11.

NO : 

Go to Step 6.

STEP 6. Connector check: B-14 inhibitor switch 
connector

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair or replace.

STEP 7. Check inhibitor switch

• Check inhibitor switch (Refer to GROUP 23A − 

On-vehicle Service 

− Inhibitor Switch Continuity 

Check ).

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Replace the inhibitor switch.

STEP 8. Perform voltage measurement at B-14 
inhibitor switch connector

• Disconnect connector, and measure at the har-

ness side.

• Ignition switch: ST

• Voltage between terminal No. 10 and earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Check intermediate connectors A-115 and 

B-10, and repair if necessary. If starter relay 
connector are normal, check and repair 
harness between A-16X (terminal No. 2) 
starter relay connector and B-14 (terminal 
No. 9) inhibitor switch connector.

• Check power supply line for open/

short circuit.

NO : 

Go to Step 9.

STEP 9. Connector check: C-307 ignition switch 
connector

Q: Is the check result normal?

YES : 

Go to Step 10.

NO : 

Repair or replace.

STEP 10. Check ignition switch

• Check ignition switch (Refer to GROUP 54A − 

Ignition switch 

− Inspection ).

Q: Is the check result normal?

YES : 

Check intermediate connectors A-115, B-

10, C-207 and C-211, and repair if 
necessary. If starter relay connectors are 
normal, check and repair harness between 
B-14 (terminal No. 10) inhibitor switch 
connector and C-307 (terminal No. 5) 
ignition switch connector.

• Check power supply line for open/

short circuit.

NO : 

Replace the ignition switch.

STEP 11. Perform voltage measurement at A-16X 
starter relay connector. 

• Disconnect connector, and measure at the har-

ness side.

• Voltage between terminal No. 4 and earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 12.

NO : 

Check and repair harness between A-16X 

(terminal No. 4) starter relay connector and 
battery.

• Check power supply line for open/

short circuit.

STEP 12. Perform resistance measurement at A-
16X starter relay connector. 

• Disconnect connector, and measure at harness 

side.

• Resistance between terminal No. 1 and earth.

OK: Continuity (2

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 13.

NO : 

Check and repair harness between A-16X 

(terminal No. 1) starter relay connector and 
body earth.

• Check earth line for open circuit and 

damage.
