Starting System: Notes
WARNING: This page is about a different car, the 2009 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
The performance of the starting system directly depends on the operation of the battery and charging systems. Always verify the battery and charging systems are operating according to specifications before diagnosing starting system faults.
| Starting System Diagnosis | ||
|---|---|---|
| CONDITION | POSSIBLE CAUSE | CORRECTION |
| STARTER FAILS TO OPERATE. | 1. Battery discharged or faulty. | 1. Refer to BATTERY SYSTEM .Charge or replace battery, if required. |
| 2. Starting circuit wiring faulty. | 2. Refer to SYSTEM WIRING DIAGRAMS . Test and repair starter feed and/or control circuits, if required. | |
| 3. Starter relay faulty. | 3. If there are DTCs related to the Starter/Engine Control Relay, refer to the appropriate diagnostics in Engine Electrical Diagnostics. Otherwise, substitute a known good starter relay, and re-test the system | |
| 4. Electronic Ignition Switch (EIS) Drive Authorization System (DAS), or ECM fault. | 4. Check for DTCs with a scan tool. If any EIS, DAS, or Starter/Engine control relay DTCs are present, refer to the appropriate engine or body system diagnostic procedures. | |
