COMMENT ON TROUBLE SYMPTOM
• Failure is possibly caused by failed starter itself
or failed related circuit.
PROBABLE CAUSES
• Failed battery
• 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 13.
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 8.
NO :
Go to Step 6.

STEP 6. Connector check: C-307 ignition switch
connector
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair or replace.
STEP 7. 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, C-
207 and C-211, and repair if necessary. If
intermediate connectors are normal, check
and repair harness between A-16X (terminal
No. 2) starter relay connector and C-307
(terminal No. 5) ignition switch connector.
• Check power supply line for open/
short circuit.
NO :
Replace the ignition switch.

STEP 8. 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 9.
NO :
Check and repair harness between A16X
(terminal No. 4) starter relay connector and
battery.
• Check power supply line for open/
short circuit.
STEP 9. 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 10.
NO :
Check and repair harness between A16X
(terminal No. 1) starter relay connector and
body earth.
• Check earth line for open circuit and
damage.
STEP 10. Connector check: A-110 starter
connector
Q: Is the check result normal?
YES :
Go to Step 11.
NO :
Repair or replace.
STEP 11. Check harness between A-110 (terminal
No. 1) starter connector and A-16X (terminal No.
3) starter relay connector.
NOTE: Before checking harness, check intermediate
connector A-27, and repair if necessary.
• Check output line for open/short circuit.
Q: Is the check result normal?
YES :
Go to Step 12.
NO :
Repair the damaged harness wire.
