Intermittent battery plug connection.
•
Main power fuse opening during regen.
•
If the power steering coil resistance is correct then:
• Defective control. Replace control unit
DESCRIPTION OF STATUS
Capacitor (1C) voltage too high.
CORRECTIVE ACTIONS
SYMPTOM
Line contactor opens and closes, then opens and can only close by opening and closing the key switch.
POSSIBLE CAUSE
• Unplugging the battery connector during regenerative braking.
• Line contactor bouncing open during regen.
Short between wires connecting to the power steering coil (wire # 10 and 60)
Shorted power steering control coil
POSSIBLE CAUSE
•
•
DESCRIPTION OF STATUS
The power steering coil current is too high during the run mode.
CORRECTIVE ACTIONS
SYMPTOM
Control will not operate.
