TROUBLESHOOTING GUIDE

The starting system troubleshooting guide is shown in the fol-
lowing steps.

WARNING

Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER 
HANDLING.

STEP 1.
Q: Is the battery in good condition? (Refer to GROUP 54A, 

Chassis Electrical 

− Battery − On-vehicle Service − 

Battery Test 

P.54A-9

.)

YES : Go to Step 2.
NO :  Charge or replace the battery.

STEP 2.

• Disconnect the starter motor S (solenoid) terminal connec-

tor.

• Using a jumper wire, apply battery positive voltage to the 

starter motor S (solenoid) terminal.

• Check the engine condition.

OK: Turns normally

Q: Does the starter motor operate normally?

YES : 

• Check the ignition switch (Refer to GROUP 54A, 

Chassis Electrical 

− Ignition Switch − Ignition 

Switch 

− Inspection 

P.54A-271

.)

• Check the starter relay system (Refer to GROUP 

13A, Multiport Fuel Injection (MFI) 

− Multiport Fuel 

Injection (MFI) Diagnosis 

− Symptom Procedures − 

Ignition Switch 

− ST System and Starter Relay 

System 

P.13A-818

 <M/T>, 

P.13A-830

 

<TC-SST>).

• Check the shift lever position. (Refer to GROUP 

22C, Twin Clutch-sportronic Shift Transmission 
(TC-SST) 

− On-vehicle Service − Shift Lever 

Operation Check 

P.22C-330

.)

• Check the line between the battery and starter 

motor S (solenoid) terminal.

NO :  Go to Step 3.

STEP 3.

• Check the cable between starter B (battery) terminal and 

battery positive terminal for connection and continuity.

Q: Is the starter cable in good condition?

YES : Go to Step 4.
NO :  Repair or replace the cable.

STEP 4.

• Check the connection and the continuity of the cable 

between the starter motor body and the negative battery 
terminal.

Q: Is the ground line in good condition?

YES : Go to Step 5.
NO :  Repair or replace the cable.

STEP 5.
Q: Is the starter motor in good condition? (Refer to Starting 

System 

− Starter Motor Assembly − Inspection

1. Disconnect the lead wire from the M-terminal of the 

magnetic switch.

2. Connect a 12-volt battery between the S-terminal and 

M-terminal.

CAUTION

This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
3. Set the switch to "ON", and the pinion will move out.

4. Check the pinion-to-stopper clearance (pinion gap) with a 

feeler gauge.

Standard value: 0.5

5. If the pinion gap is out of specification, adjust by adding or 

removing gasket(s) between the magnetic switch and front 
bracket.

1. Disconnect the field coil wire from the M-terminal of the 

magnetic switch.

CAUTION

This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the S-terminal and 

M-terminal.

3. If the pinion moves out, the pull-in coil is good. If it doesn't, 

replace the magnetic switch.
