Code 53425 or 33425

Cause Of Fault
Defective left rear inlet valve, break in continuity/ short- circuit to ground/+ 12 V in the wiring loom of the valve or defective Electronic Control Unit (ECU).

Symptom
The ANTI LOCK light is lit..

Action
1. With the ECU disconnected, check the circuit between pins 54 and 3 of the Antilock Brake System (ABS) ECU via the breakout box.
- The resistance should be 7 ohms ± 10%.
- If the circuit is OK, clear the trouble code and test-drive the car to check whether the trouble code is triggered again.
If so, see Actions Before Replacing ECU.
- If the circuit is defective, continue as follows:
2. Check that the winding of the IF valve is intact by measuring the resistance between pins 2 and 10 or 1 on the valve body.
- If the resistance is incorrect, fit a new hydraulic unit.
- If the resistance is now correct, the fault is in the wiring harness, go to step no. 3.
3. Check the brown and white wire between pin 2 on the connector of the valve housing and pin 54 on the ABS ECU for a break in continuity/short-circuit.
4. Check the wire between pin 10 or 1 on the connector of the valve housing and pin 3 on the ABS ECU for a break in continuity/short-circuit.
