DTC 39

TROUBLE CODE 39
- FAULTY SOLENOID VALVE CIRCUIT(S) IN HYDRAULIC UNIT-

DIAGNOSIS:
- Faulty harness/connector
- Faulty solenoid valve in hydraulic unit
- Faulty A.B.S. control module





TROUBLE SYMPTOM:
- A.B.S. does not operate.





1. CHECK RESISTANCE OF SOLENOID VALVE TO A.B.S. CONTROL MODULE SIDE.
1) Turn ignition switch OFF.
2) Disconnect connector from A.B.S. control module.
3) Measure resistance between A.B.S. control module connector terminals.

33 / (P4) No.2 - No.32
39 / (P4) No.18 - No.32
Specified resistance: approx. 1 ohms





2. CHECK VOLTAGE OF SOLENOID VALVE TO A.B.S. CONTROL MODULE SIDE.
1) Turn ignition switch OFF.
2) Disconnect valve relay from hydraulic unit.
3) Turn ignition switch ON.
4) Measure voltage between A.B.S. control module connector terminals.

31 / (P4) No.35 - No.20
33 / (P4) No.2 - No.20
39 / (P4) No.18 - No.20
Specified voltage: 0 V





3. CHECK HARNESS BETWEEN A.B.S. CONTROL MODULE AND HYDRAULIC UNIT.
1) Turn ignition switch OFF.
2) Disconnect connector from hydraulic unit.
3) Turn ignition switch ON.
4) Measure voltage between A.B.S. control module connector terminals.
