Inspection and verification
1. Make sure the customer's complaint is valid.
2. Visually inspect for obvious mechanical and electrical problems.
Mechanical factors | Electrical Factors |
3. If an obvious cause of a problem you identified or described by a customer is found, resolve it before proceeding to the next steps (if possible).
4. Use an approved diagnostic system or scan tool (tester), to retrieve all DTCs before referring to the symptom table or DTC index (DTC).
Clear all DTCs after troubleshooting.
Symptom table
Symptom | Possible reasons | Actions |
Engine won't crank (starter does not turn) | Make sure the gear selector is in P or N and adjusted correctly. Check the condition and charge of the battery. Check for DTCs (DTC), indicating a malfunction of the immobilizer. Check the electrical circuits of the starter relay, ignition switch and alternator. Refer to the electrical manual. Check for TCM and ECM DTCs. Check if the engine turns freely. | |
Engine won't crank (starter rotates) | Check starter installation (tightening of fastening elements, correct location of the starter relative to the engine, etc.). Check the flywheel/faceplate ring gear for damage, foreign objects, etc. | |
Engine cranks too slowly | Check the condition and charge of the battery. Check starter electrical circuits. Refer to the electrical manual. Check the brand and condition of the engine oil. | |
Engine cranks too fast | Low compression in the engine | Check the compression in the cylinders. |
Increased starter noise | Check starter installation (tightening of fastening elements, correct location of the starter relative to the engine, etc.). Check the condition of the starter housing. Check the flywheel/faceplate ring gear for damage, foreign objects, etc. |
DTC index
NOTE: Universal Scan Tools cannot read the listed codes or can only read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the listed 7 digit code to identify the problem (the last 2 digits give additional information read by the diagnostic system approved by the manufacturer).
NOTE: See Section 303-14 for a complete list of ECM DTCs "Electronic engine management system" in the workshop manual.
DTCs | Description | Possible reasons | Actions |
P051216 | Starter enable circuit | Starter Enable Circuit Low Input Voltage | Refer to the electrical manual and check the starter engagement circuit. Repair/replace as needed. |
P051217 | Starter enable circuit | Starter enable circuit high input voltage | Refer to the electrical manual and check the starter engagement circuit. Repair/replace as needed. |
P051300 | Wrong immobilizer key | Invalid security key | Program the keys using an approved diagnostic system. Investigate and perform the necessary actions on all codes located in the memory of other CAN·modules. Erase the codes and recheck. |
P061600 | Low voltage in the starter relay circuit | Check starter relay operation. Refer to the electrical manual and check the starter relay circuit. Repair/replace as needed. | |
P061700 | High voltage in the starter relay circuit | Check starter relay operation. Refer to the electrical manual and check the starter relay circuit. Repair/replace as needed. | |
P063305 | Immobilizer key not programmed -ECM/PCM | Failed to transfer the target ID for the security system | Program the key using an approved diagnostic system. |
P063355 | Immobilizer key not programmed -ECM/PCM | Security system: missing target value in EMS | Program the module using an approved diagnostic system. |
B1C5024 | Starter switch | Refer to the electrical manual and check the ignition switch circuit. Check switch operation and replace if necessary. |
