DIAGNOSTIC CODE INDEX

Diagnostic Test

  1. 1) CHECK FOR ANY POWERTRAIN CONTROL MODULES DTCS NOTE: Make sure the Battery is in good condition. Using the Midtronics Battery Tester, test the Battery before continuing. NOTE: Inspect the vehicle for after market accessories that may exceed the Generator System output. NOTE: Make sure the generator drive belt is in good operating condition. NOTE: Inspect the fuses in the IPM. If an open fuse is found, use the wire diagram/schematic as a guide, inspect the wiring and connectors for damage. Turn the ignition on. With the scan tool, read active PCM DTC's. Does the scan tool display any active PCM DTC's? Yes Refer to the appropriate Engine ELECTRICAL DIAGNOSTICS article for the diagnostic test procedure.
