Causes: • AMDP program defective. • IC card defective • IPU defective
Code: SC302
Description: Charge Corona Output Error
Charge corona feedback voltage of less than 1V was detected for more than 200 s.
Causes: • Charge power pack is defective. • High voltage cable is defective. • Poor connection of the power pack connector. • Dirty charge corona unit caused leakage.
Code: SC303
Description: Charge corona wire cleaner error
1) Wire cleaner motor feedback voltage of less than 0.1 V was detected for more than 1s. 2) Corona wire cleaning did not complete within 80 s. 3) Charge wire cleaner did not return to the home position. 4) Cleaner does not move from the home position.
Causes: Wire cleaner motor connector disconnected. Wire cleaner motor connector disconnected. Wire cleaner motor is operating without a load. Wire cleaner stops due to an overload. Wire cleaner motor drive circuit malfunction.
Code: SC306
Description: Charge grid output error
Control PWM duty value is higher than 1% (FB less than 1V) for more than 200 ms (a grid current leak).
Causes: • CBG power pack is defective. • High voltage cable is defective. • Poor connection of the power pack connector. • Dirty charge corona unit causing leakage
Code: SC330
