Inspection and Verification
| WARNING | When working underhood in the vicinity of the starter motor, be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times. A protective cap or boot is provided over the terminal of this lead and must be reinstalled after repairing |
| WARNING | When working in the area of the starter motor, be careful to avoid touching hot exhaust components. |
Note. The anti-theft system must be functioning correctly before a logical starting system diagnosis can be carried out. Address anti-theft concerns before continuing.
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART Mechanical Electrical Starter motor Cover plate Ring gear teeth Battery Fuse(s) Wiring harness Starter relay Loose or corroded connections Anti-theft system Starter switch (manual transaxle only)
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle: Check that the program card is correctly installed. Check the connections to the vehicle. Check the ignition switch position.
- If the diagnostic tool still does not communicate with the vehicle, REFER to the diagnostic tool operating manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with: Appropriate communication networks, such as SCP, ISO, UBP, CAN circuit fault; all electronic control units no response/not equipped, REFER to «MODULE COMMUNICATIONS NETWORK»(ref-255415) . No response/not equipped for generic electronic module (GEM), REFER to «MULTIFUNCTION ELECTRONIC MODULES»(ref-255417) . System passed, RETRIEVE and RECORD the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the GEM.
- If there are diagnostic trouble codes (DTC) that are available, VERIFY the DTC and GO to «STARTER AND PASSIVE ANTI-THEFT SYSTEM (PATS) DIAGNOSTIC TROUBLE CODE (DTC) INDEX»(ref-255384-S13254437132007053100000) .
- If no DTCs related to the concern are retrieved GO to «SYMPTOM CHART»(ref-255384-S30840126332007053100000) .

SYMPTOM CHART
Starter Motor - Load Test
Note. The batteries must be fully charged before carrying out a starter load test.
- Set the parking brake and shift the transmission into the NEUTRAL position.
- Connect the Alternator, Regulator, Battery and Starter Tester (ARBST). Follow the manufacturer's supplied instructions.
- Connect a remote starter switch across the starter relay S-terminal and the battery positive terminal post.
- Turn the ignition switch to the RUN position.
- Crank the engine and record the voltmeter reading.
- Turn the carbon pile control knob until the voltmeter indicates the same reading recorded during cranking the engine. Record the ammeter reading.
- Compare the ammeter reading with specifications.
Starter Motor - No-Load Test
- Connect a fully charged battery to the starter.
- Connect the Alternator, Regulator, Battery and Starter Tester (ARBST) as illustrated.
- Connect a remote starter switch between the starter solenoid S-terminal and the positive battery terminal post.
- Press the remote starter switch. The pinion should shift to the crank position and the motor should run smoothly.
- While the starter motor is running, record the voltmeter and ammeter readings.
- The voltage reading should be greater than 11.0 volts and the amperage should be no more than 200 amps.
Starter Motor - Motor Feed Circuit Voltage Drop Test
- This test is carried out to determine if slow cranking is caused by high resistance in the starter motor circuit wiring.
- The voltage drop test can only be carried out with the starter motor on the vehicle.
- Disconnect the fuel pump electrical connector.
- Connect the positive lead of the 73 Digital Multimeter to the battery positive (+) post, and the negative lead to the starter solenoid M-terminal.
- Connect a remote starter switch between the starter solenoid S-terminal and the positive battery terminal post.
- Press the remote starter switch and record the voltage reading.
- The voltage reading should be 0.5 volt or less. A reading higher than 0.5 volt indicates high resistance.
- Repeat the test on the starter solenoid B-terminal.
- If the readings are higher than 0.5 volt, remove the wiring from the starter solenoid.
- Clean and inspect each wire connector and the starter solenoid terminals.
- Install the wires onto the starter solenoid and retest.
- If the reading at the starter solenoid M-terminal is still higher than 0.5 volt or the reading at the B-terminal is lower, carry out the Starter Solenoid Component Test. If no change is noted, install a new positive battery cable lead.
Starter Motor - Motor Ground Circuit Voltage Drop Test
Note. A slow cranking condition can also be caused by high resistance in the ground circuit.
- Disconnect the wiring from the fuel pump electrical connector.
- Connect the Digital Volt-Ohmmeter positive lead to the starter motor housing.
- Connect the Digital Volt-Ohmmeter negative lead to the battery negative (-) terminal.
- Connect a remote starter switch between the starter solenoid S-terminal and the positive battery terminal post.
- Press the remote starter switch and record the voltage reading.
- The voltage reading should be 0.2 volt or less. If the voltage reading is higher, remove and clean the negative cable connections at the battery, starter motor and the body.
- Retest the system. If readings are still higher than 0.2 volt, test each individual negative cable.
