Trouble Shooting
CAUTION:
Electronic modules are sensitive to static electrical charges. Proper grounding of technician and electrical parts is essential to prevent damage.
Verify charging system, turn signals, headlights and cruise control are working properly. Inspect wiring harness for obvious signs of shorts, opens, bad connections or damage. Verify customer concern by operating system in question. Attempt to duplicate condition with ignition switch in RUN position with engine off, in START position before ignition switch is released and in RUN position with engine running. Visually inspect the following components:
- Damaged Fuel Tank
- Coolant Level
- Coolant Temperature Gauge
- Engine Oil Level
- Engine Oil Pressure Gauge
- Engine Oil Pump
- Engine Thermostat
- Blown Fuse(s)
- Damaged Instrument Cluster
- Damaged Switches, Sensors Or Modules
- Damaged Wiring Harness
- Light Bulbs Inoperative
- Loose Or Corroded Connections
If inspection reveals an obvious concern which can be easily serviced, repair as necessary. If inspection does not reveal an obvious concern which can be easily serviced, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM .
