TROUBLE SHOOTING

Note. Trouble shooting or diagnostic testing information is not available from manufacturer. See WIRING DIAGRAMS .

PRELIMINARY INSPECTION

Verify customer complaint by operating suspected system. Visually inspect for obvious signs of mechanical and electrical damage. For mechanical damage, check for the following

  1. Starter motor. (Схема №11)
  2. Flywheel ring gear.
  3. Seized engine.

For electrical damage, check for the following

  1. Battery condition and state of charge.
  2. Starter motor.
  3. Fuse No. 5 of the Engine Management System (EMS) fuse box and fuse No. 3 of the engine compartment fuse box. See «FUSES & CIRCUIT BREAKERS»(ref-165714) article in ELECTRICAL.
  4. High power protection module. (Схема №7)
  5. Starter Relay. (Схема №6)
  6. Ignition Switch. (Схема №9)
  7. Body Processor Module (BPM) and Engine Control Module (ECM). (Схема №5)
  8. Inspect for loose or corroded connection, damaged wiring harnesses and/or switches. Check for broken or partially broken wires inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected.
  9. Ensure any aftermarket electronic equipment is properly installed.

If a fault is found, repair as necessary. If no fault is found during a preliminary inspection, see SELF-DIAGNOSTIC SYSTEM for additional information.

SELF-DIAGNOSTIC SYSTEM

Note. If a DTC cannot be cleared, then there is a permanent fault present that flags again as soon as it is cleared. The exception to this is DTC P1260, which will only clear following an ignition OFF/ON cycle after rectification.

Before performing any repairs, ensure Diagnostic Trouble Codes (DTC) are not set. See SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. If any DTCs are present, diagnose accordingly. If no DTCs are present, go to SYSTEM TEST .

SYSTEM TEST

CAUTIONTo prevent damaging wiring harness connector terminals, use adaptor kit, part number 3548-1358-00 when probing connectors to take measurements.

Note. When performing electrical voltage or resistance tests, always use a Digital Volt-Ohmmeter (DVOM) accurate to 3 decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DVOM leads into account.
