W/Harness Inspection

Intelligent Accel Pedal
C1104 Ignition Voltage High - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
3. Has a problem been found?






Charging System Inspection

1. Engine "ON"
2. headight and heatwire "ON".
3. Measure voltage between terminal (+) and (-) of battery while maintaining ENG RPM 2,500RPM over 2 minutes.

Specification :Less than 17 [V]




4. Is the measured voltage within specifications?






Power Circuit Inspection
