Re: ABS Warning light on, help!
I haven't done this on a GTV but it seems that most Bosch ABS units have a self-diagnosis mode with identical codes. (Definitely the 2e and the 5.3).
The GTV has a Bosch 2something system with an identical electronic control unit perched on top of it to the 2e I diagnosed.
You find the diag connector, 3 pins, near the passenger side suspension strut/relays etc. Then you earth the A lead, turn on the ignition and start counting the flashes.
There are so many potential faults that aside from checking both your rear brake light bulbs are working (that can cause a fault) you need the diags.
The diag connector is shown in this photo with a ring round it. The ABS unit has the square round it. Mine's a 5.3 so yours will look a little different.
Here are the codes etc.
Earth Pin a of connector T8 which is a black 3 position unconnected diagnostic connector by the bulkhead on the passenger side.
Now turn on the ignition and count the ABS light flashes.
The first number will be 12 which is 1 flash, pause, 2 flashes.
then 12 another 2 times.
Now comes your fault code. The system can spew out up to 3 codes I think.
16- Faulty LH Solenoid Valve
17- Faulty RH Solenoid Valve
18- Faulty Rear Solenoid Valve
19- Faulty Safety Relay
25- Incorrect number of phonic wheel teeth
35- Faulty Pump Motor
37- Faulty brake switch
39- Faulty LH sensor front
41- LH front sensor not connected
42- Faulty RH sensor front
43- RH front sensor not connected
44- Faulty LH Rear sensor
45- LH Rear sensor not connected
46- Faulty RH Rear sensor
47- RH Rear Sensor not connected.
48- Insufficient supply voltage
55- Faulty ECU (ABS)
When you start getting 3 12s again it has finished.
