Checking the starter
Note: Before starting the test, the air temperature must be between 15 and 38°C
Recommended order
- Use a starter system tester.
- Connect and use equipment in accordance with the manufacturer's instructions.
- Perform checks as described.
Alternative order
- Use the following equipment:
- Ammeter, 0-400 A
- Voltmeter, 0-20V (with an accuracy of 0.1 volt).
- Tachometer, 0-1,200 rpm.
- Connect the voltmeter and ammeter as shown.
Note: After checking or repairing, reset the ECM/PCM memory to clear all fault codes.
Check the starter engagement:
1. Remove fuse No.44 (15A) from the underhood fuse box and relay.
2. Turn the ignition switch to START (III) with the shift lever in the [N or [P] position (A/T) or neutral position (M/T). The starter should turn the engine.
- If the starter does not turn the engine, refer to step 3,
- If it cranks the engine erratically or too slowly, refer to the chapter "Check for wear and damage".
3. Check the battery, positive battery cable, ground, starter lock relay and wire connections for looseness and corrosion, check again. If the starter still does not turn the engine, go to step 4.
4. Pull out the connector (BLK/WHT wire and solenoid contact) from the starter.
5. Connect the connecting wire from the positive contact of the battery [+) to the contact of the solenoid 1. The starter must turn the engine.
- If the starter still does not turn the engine, remove it and check for problems inside the starter.
- If the starter turns the engine, proceed to step 6.
6. Check the ignition switch.
7. Check the starter interlock relay.
8. Check the AD gear position indicator switch.
9. Check for a break in the wiring between the ignition switch and the starter.
10. Check the engine blocking system.
Check for wear and damage
The starter should turn the engine smoothly and steadily. If the starter engages but does not turn the engine steadily, remove it and inspect the starter pinion and torque converter or flywheel ring gear for damage.
- Check the pinion clutch for binding or slipping when the rotor is rotating with the pinion gear secured.
- If damaged, replace the gear.
Check the starting voltage or starting current.
The voltage at startup must be at least (*1) volts.
The starting current must be at least (*2) amperes.
*1
- Hitachi: 8.0
- Nippondenso: 8.0
- Mitsuba: 8.5
*2
- Hitachi: 200
- Nippondenso: 200
- Mitsuba: 350
If the cranking voltage is too low or the cranking current is too high, check for:
- The battery is damaged or weakly charged.
- Open circuit in the contact plate starter.
- Anchor jamming.
- The armature winding is closed.
- Excessive resistance in the engine.
Check RPM when starting
Engine speed during starting Should be above 100 rpm.
If the speed is too slow, check the following:
- The battery or starter contacts are loose.
- The starter brushes are excessively worn.
- Open circuit of starter contact plate.
- The helical cuts or drive gear are dirty or damaged.
- The overrunning clutch of the drive gear is damaged.
Checking the starter disconnect
With the shift lever in the [N] or [P] position (A/T) or neutral position (M/T), turn the ignition switch to START (III) and release it to ON (II).
The starter pinion should disengage from the torque converter or flywheel ring gear when you release the key.
If the pinion gear is engaged with the torque converter or flywheel ring gear, check the following:
- Solenoid core and switch failure.
- The pinion assembly is dirty or the overrunning clutch is damaged
