Starter Circuit Troubleshooting

NOTE:
• Air temperature must be between 59° and 100°F (15°
and 38°C) during this procedure.
• After this test, or any subsequent repair, reset the
powertrain control module (PCM) to clear any
diagnostic trouble codes (DTCs) (see page 11-4).
• The battery must be in good condition and fully
charged.
• If you disconnect the battery, do the PCM idle learn
procedure (see page 11-202).
Recommended Procedure:
• Use a starter system tester.
• Connect and operate the equipment in accordance
with the manufacturer's instructions.
Alternate Procedure
1. Hook up the following equipment:
• Ammeter, 0 400A around both negative battery
cables
• Voltmeter, 0 20 V (accurate within 0.1 volt)
• Tachometer, 0 1,200 rpm
2. Remove the No. 1 (15A) fuse from the under-hood
fuse/relay box.
3. With the shift lever in P or N, turn the ignition
switch to start (III).
Did the starter crank the engine normally?
YES The starting system is OK.
NO Go to step 4.
4. Check the battery condition. Check electrical
connections at the battery, the negative battery
cable to the body, engine ground cables, and the
starter for looseness and corrosion. Then try
starting the engine again.
Did the starter crank the engine normally?
YES Repairing the loose connection fixed the
problem. The starting system is now OK.
NO If the starter will not crank the engine at all, go
to step 5. If it cranks the engine erratically or too
slowly, go to step 7. If it won't disengage from the
torque converter ring gear when you release the
key, check for the following until you find the cause.
• Solenoid plunger and switch malfunction
• Dirty drive gear or damaged overrunning clutch.
5. Make sure the transmission is in P or N, then
disconnect the BLK/WHT wire (A) from the starter
solenoid (B). Connect a jumper wire from the
battery positive terminal to the solenoid terminal.
