M59 terminal 1 and ground
2.CHECK HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CONTROL UNIT FOR OPEN
- Turn ignition switch OFF.
- Disconnect power steering solenoid valve connector.
- Disconnect power steering control unit connector.
- Check continuity between power steering solenoid valve connector
E14 (A) terminals 1, 2 and power steering control unit
connector M59 (B) terminal 1, 5.
3.CHECK HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CONTROL UNIT FOR SHO
- Check continuity between power steering solenoid valve connector
E14 terminals 1, 2 and ground. - Turn ignition switch ON.
