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: Dose the starter motor operate normally?

YES :

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

Chassis Electrical

− Ignition Switch − Ignition

Switch

− Inspection

P.54A-43

.)

• Check the starter relay.

• Check the transmission range switch. (Refer to

GROUP 23A, Automatic Transaxle

− On-vehicle

Service

− Essential Service − Transmission Range

Switch Check

P.23A-408

.)

• 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

PINION GAP ADJUSTMENT
1. Disconnect the field coil 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

− 2.0 mm (0.02 − 0.07 inch)

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

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