Troubleshooting Hints - Starting System

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
^ Check for Central Control Module (CCM) Diagnostic Trouble Code (DTC) 42 and 43. If present, refer to Central Control Module. Also check for Powertrain Control Module (PCM) Diagnostic Trouble code (DTC) P1626. DTC P1626 will be stored in the PCM memory but will not turn "ON" the Malfunction Indicator Lamp (MIL). If present, refer to Powertrain Management Testing and Inspection
1. Visually inspect the hydrometer (built into Battery).
^ Green dot - Battery is charged.
^ Dark dot - Charge and load test Battery. If battery passes load test, refer to System Diagnosis.
^ Clear or light yellow dot Battery electrolyte is low. Replace Battery.
2. Check that Starter Solenoid terminals "S" and "B" and Battery connections are clean and tight.
3. Check that Maxifuse #3 and I/P Fuse #24 are OK. If these fuses are open, check for a short to ground in CKT 1242, CKT 5 or CKT 806.
4. Check that G100 and G101 are clean and tight.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (see Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis.
