Troubleshooting Starter Circuit
Note. The battery must be in good condition and fully charged.
- Disconnect the injector connectors.
- With the shift lever in N or P (A/T) or clutch pedal pressed (M/T), turn the ignition switch to "START". If the starter normally cranks the engine, starting system is OK. If the starter will not crank the engine at all, go to next step. If it won't disengage from the ring gear when you release key, check for the following until you find the cause. Solenoid plunger and switch malfunction. Dirty pinion gear or damaged overrunning clutch.
- Check the battery condition. Check electrical connections at the battery, battery negative cable connected to the body, engine ground cables, and the starter for looseness and corrosion. Then try starting the engine again. If the starter cranks the engine normally, repairing the loose connection repaired the problem. The starting system is now OK. If the starter still does not crank the engine, go to next step.
- Disconnect the connector from the S-terminal of solenoid. Connect a jumper wire from the B-terminal of solenoid to the S-terminal of solenoid. If the starter cranks the engine, go to next step. If the starter still does not crank the engine, remove the starter, and repair or replace as necessary.
- Check the following items in the order listed until you find the open circuit. Check the wire and connectors between the driver's under-dash fuse/relay box and the ignition switch, and between the driver's under-dash fuse/relay box and the starter. Check the ignition switch (Refer to «IGNITION SWITCH ASSEMBLY»(ref-537276) . Check the transaxle range switch connector or ignition lock switch connector. Inspect the starter relay.

- Disconnect the field coil wire from the M-terminal of solenoid switch.
- Connect the battery as shown. If the starter pinion pops out (engages), it is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
- Disconnect the battery from the M terminal. If the pinion does not retract, the hold-in coil is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
- Disconnect the battery also from the body. If the pinion retracts immediately, it is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.

- Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12-volt battery to starter motor as follows.
- Connect a test ammeter (150-ampere scale) and carbon pile rheostat as shown in the illustration.
- Connect a voltmeter (15-volt scale) across starter motor.
- Rotate carbon pile to the off position.
- Connect the battery cable from battery's negative post to the starter motor body.
- Adjust until battery voltage shown on the voltmeter reads 11.5 volts.
- Confirm that the maximum amperage is within the specifications and that the starter motor turns smoothly and freely. Max. Current Non-ISG: 60A ISG: 100A Min. Speed Non-ISG: 2, 400 rpm ISG: 1, 915 rpm

- Disconnect the battery negative cable. Tightening torque: 3.9 ~ 5.9 N.m (0.4 ~ 0.6 kgf.m, 3.0 ~ 4.4 lb-ft)
- Remove the air duct and air cleaner assembly. (Refer to " «ENGINE AND TRANSAXLE ASSEMBLY»(ref-537192-S30675217252013032200000) ")
- Disconnect the starter cable (A) from the B - terminal on the solenoid and the connector (B) from the S terminal. Tightening torque: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
- Remove the starter (A). Tightening torque: 42.2 ~ 53.9 N.m (4.3 ~ 5.5 kgf.m, 31.1 ~ 39.8 lb-ft)
- Installation is the reverse of removal.

- Disconnect the M-terminal (A) on the magnet switch assembly.
- After loosening the screws (A), detach the magnet switch assembly (B).
- Loosen the through bolts (A).
- Remove the brush holder assembly (A), armature assembly (B) and yoke assembly (C).
- Remove the gasket sheet (A) and lever stop (B).
- Remove the reducer assembly (A) and lever (B).
- Press the stopper (A) using a socket (B).
- After removing the stop ring (A) using stop ring pliers (B).
- Disconnect the stopper (A), overrunning clutch (B) and internal gear (C). NOTE: Using a suitable pulling tool (A), pull the overrunning clutch stopper (C) over the stop ring (B).
- Reassembly is the reverse of disassembly.

- Remove the starter.
- Disassemble the starter as shown at the beginning of this procedure.
- Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature.
- Check the commutator (A) surface. If the surface is dirty or burnt, resurface with emery cloth or a lathe within the following specifications, or recondition with #500 or #600 sandpaper (B).
- Check the commutator diameter. If the diameter is below the service limit, replace the armature. Commutator diameter Standard (New): 27.0 mm (1.06 in.) Service limit: 26.0 mm (1.02 in.)
- Measure the commutator (A) runout. If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments. If the commutator run out is not within the service limit, replace the armature. Commutator runout Standard (New): 0.05 mm (0.0019 in.) max Service limit: 0.08 mm (0.0031 in.)
- Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica (C) between the commutator segments. The undercut should not be too shallow, too narrow, or v-shaped (D). Commutator mica depth Standard (New): 0.8 mm (0.0314 in.) Limit: 0.2 mm (0.0079 in.)
- Check for continuity between the segments of the commutator. If an open circuit exists between any segments, replace the armature.
- Check with an ohmmeter that no continuity exists between the commutator (A) and armature coil core (B), and between the commutator and armature shaft (C). If continuity exists, replace the armature.
Inspect Starter Brush
Brushes that are worm out, or oil-soaked, should be replaced.

Starter Brush Holder Test
Make sure there is no continuity between the (+) brush holder (A) and (-) plate (B). If there is continuity, replace the brush holder assembly.

- Slide the overrunning clutch along the shaft. Replace it if does not slide smoothly.
- Rotate the overrunning clutch both ways. Does it lock in one direction and rotate smoothly in reverse? If it does not lock in either direction or it locks in both directions, replace it.
- If the starter drive gear is worn or damaged, replace the overrunning clutch assembly. (the gear is not available separately). Check the condition of the flywheel or torque converter ring gear if the starter drive gear teeth are damaged.
