The starter motor is rated as a 1.8kW and is a Denso level three-sealed unit. It is an RA type starter motor, which is of the offset design with the solenoid being directly behind the pinion to give a more positive engagement to the ring gear. The motor is geared directly to the pinion. Each starter motor is of the pre-engaged type and comprises a series wound motor and an overrunning clutch. This starter incorporates labyrinth-breathing tubes to help with sealing and drainage.
The starter solenoid is energized by a signal from the Engine Control Module (ECM) when the ignition switch is moved to the crank position. When engine cranking is requested, the ECM checks that a valid key code has been received before granting the crank request.
The power for starter operation is supplied on a substantial single cable connected direct from the battery positive terminal. The cable is connected to the solenoid via a copper threaded stud with an anti-rotational device and secured with a nut.
The starter motor is located on the rear RH side of the engine block. The motor is secured to the block and protrudes through an aperture to drive the flywheel via a ring gear.
OVERVIEW
For information on the operation of the system, refer to the relevant service information.
INSPECTION AND VERIFICATION
- Verify the customer concern.
- Visually inspect for obvious mechanical or electrical faults. VISUAL INSPECTION Mechanical Electrical Gear selector lever cable adjustment (vehicles with automatic transmission) Starter motor Engine (turns freely) Battery Fuses Central and battery junction boxes Megafuses Wiring harness (es) Damaged, loose or corroded connectors Ignition switch Starter relay Transmission control module (TCM) Engine control module (ECM)
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto the symptom chart or DTC index. Make sure that all DTCs are cleared following rectification.
SYMPTOM CHART
| Symptom | Possible causes | Action |
|---|---|---|
| The engine does not crank (starter motor does not turn) | Gear selector not in P or N position (vehicles with automatic transmission) Battery Starter relay Invalid key code received by central junction box (CJB) Harness/Connectors Starter motor Ignition switch Generator Transmission control module (TCM) Engine control module (ECM) Engine seized | Make sure the gear selector is in the P or N position and correctly adjusted. Check the battery condition and state of charge. Check for DTCs indicating an immobilizer fault. Check the starter motor relay, ignition switch and generator circuits. Refer to the electrical guides. Check for TCM and ECM DTCs. Check that the engine turns freely. |
| The engine does not crank (starter motor does turn) | Starter motor installation Starter motor Flywheel/Drive plate ring gear | Check the starter motor installation (fasteners tight, starter motor square to engine, etc). Check the flywheel/drive plate ring gear teeth for damage, foreign objects, etc. |
| Engine cranks too slowly | Battery Harness/Connectors Starter motor Oil grade | Check the battery condition and state of charge. Check the starter motor circuits. Refer to the electrical guides. Check the engine oil grade and condition. |
| Engine cranks too fast | Low engine compression | Check the engine compressions. |
| Excessive starter motor noise | Starter motor Flywheel/Drive plate ring gear Starter motor installation/casing | Check the starter motor installation (fasteners tight, motor square to engine, etc). Check the starter motor casing condition. Check the flywheel/drive plate ring gear teeth for damage, foreign objects, etc. |
DTC INDEX
Note. Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system). For a full list of ECM DTCs, refer to DTC index .
| DTC | Description | Possible causes | Action |
|---|---|---|---|
| P051216 | Starter Request Circuit | Crank request circuit low input | Refer to the electrical guides and check the starter circuit. Repair/renew as necessary. |
| P051217 | Starter Request Circuit | Crank request circuit high input | Refer to the electrical guides and check the starter circuit. Repair/renew as necessary. |
| P051300 | Incorrect Immobilizer Key | Security key invalid | Program keys using the approved diagnostic system. Investigate and repair any codes stored in other CAN modules. Clear the codes and retest. |
| P061600 | Starter Relay Circuit Low | Starter relay drive circuit short circuit to ground Starter relay drive circuit high resistance Starter relay failure | Check the starter relay operation. Refer to the electrical guides and check the starter relay circuit. Repair/renew as necessary. |
| P061700 | Starter Relay Circuit High | Starter relay drive circuit short circuit to battery Starter relay failure | Check the starter relay operation. Refer to the electrical guides and check the starter relay circuit. Repair/renew as necessary. |
| P063305 | Immobilizer Key Not Programmed - ECM/PCM | Security target ID transfer process failed | Program the key using the approved diagnostic system. |
| P063355 | Immobilizer Key Not Programmed - ECM/PCM | Security no target in EMS | Program the module using the approved diagnostic system. |
| B1C5024 | Crank Switch | Ignition switch crank position short circuit Ignition switch fault | Refer to the electrical guides and check the ignition switch circuit. Check the switch operation, renew as necessary. |
