Cause Procedure, measuring location, criteria and remarks
1 Defective fuse No.4 If the fuse is broken, the circuit probably has a grounding fault, etc.
2
Defective washer motor
(internal open circuit or ground
fault)
1. Turn starting switch to OFF position.
2. Disconnect connector M06 and connect T-adapters to male side.
Between M06 (male) (1) and (2) Resistance 5 to 20 z
Between ground and M06 (male) (1) or (2) Resistance Min. 1 Mz
3
Defective diode array D02
(Internal short circuit)
1. Turn starting switch to OFF position.
2. Disconnect connector D02 and connect T-adapters to male side.
a Check the continuity in diode range.
Between D02 (male) (7) (+) and (3) (-) Continuity
Between D02 (male) (3) (+) and (7) (-) No continuity
4
Ground fault in wiring harness
(contact with ground circuit)
1. Turn starting switch to OFF position.
2. Remove fuse No.4
3. Disconnect connectors M06, C01, and D02, and connect T-adapters to
either female side.
Between F01 (4) or M06 (female) (2) or D02
(female) (3) and ground
Resistance Min. 1 Mz
Between C01 (female) (3) or M06 (female) (1) or
D02 (female) (7) and ground
Resistance Min. 1 Mz
5
Hot short circuit in wiring harness
(contact with 24 V circuit)
1. Turn starting switch to OFF position.
2. Disconnect connectors C01 and M06 and connect T-adapters to female
side of C01.
3. Remove fuse No.4
4. Turn starting switch to ON position.
a Ignore failure code displayed on machine monitor.
Between C01 (female) (3) and ground Voltage Max. 1 V
6 Defective pump controller
If no failure is found by above checks, pump controller is defective. (Since this
is an internal defect, troubleshooting cannot be performed.)
