Repair procedures
The air temperature must be between 59 and 100°F (1 5 and 38°C) before testing.
Use a starter system tester.
Connect and operate the equipment in accordance with the manufacturer's instructions.
Test and troubleshoot as described.
Use the following equipment :
- Ammeter, 0~400A
- Voltmeter, 0~20V (accurate within 0.1 volt)
- Tachometer, 0~1,200 rpm
After this test, or any subsequent repair, reset the ECM/PCM to clear any codes.
1. Remove the No.8(10A) fuse from the fuse/relay box.
2. Turn the ignition switch to START (III) with the shift lever in "P" or " N" position (A/T) or with the clutch pedal
depressed (M/T). The starter should crank the engine.
A. If the starter does not crank the engine, go to step 3.
B. If it cranks the engine erratically or too slowly, go to "Check for Wear and Damage" on the next page.
3.
Check the battery, battery positive cable, ground, starter cut relay, and the wire connections for looseness and
corrosion. Test again.
If the starter still does not crank the engine, go to step 4.
4. Unplug the connector from the starter.
5. Connect a jumper wire from the battery positive (+) terminal to the solenoid terminal.
The starter should crank the engine.
A. If the starter still does not crank the engine, remove it, and diagnose its internal problem.
B. If the starter cranks the engine, go to step 6.
6. Check the ignition switch.
7. Check the starter relay (see page EE-46 ).
8. Check the A/T gear position switch (A/T) or the clutch interlock switch (M/T).
9. Check for an open in the wire between the ignition switch and starter.
