Land Rover Repair: Discovery ABS remains on after brake work, wheel sensors, diagnosis procedure

Question
I hope you can help.  I replaced the front pads in my 94 Disco and the next day my ABS light came on and the ABS pump won't shut off.  Any suggestions on a remedy would be appreciated.
Thanks

Answer
Hi Vaanii,

some would consider pulling the ABS fuse as a temporary measure.  Satelite 1 fuse 4 for ABS brakes; Satelite 2 fuse 3 for ABS braking.

In the engine compartment, there is Fuse 5 for the ABS valve and the larger main circuit 8 for the ABS pump itself.

Sounds like the a sensor problem after a brake job BUT it could be anything along the ABS path.

Someone once said that they adjusted the brake sensor position to resolve this  but I'm not sure how it was done.  It may be possible to move the sensors.

Here's what i found for you:

ABS FAULT DIAGNOSIS
If a fault has occurred, or has been identified by ECU self diagnostic function and ABS warning light is illuminated. The system and components must be checked to locate and rectify fault, using Testbook diagnostics.
NOTE: If warning lamp has indicated a fault in system, and no fault code has been stored in memory, cause of fault is:
a) Failure in electrical supply
b) Bad ECU ground
c) Faulty warning light relay
d) ECU not connected
Before commencing fault diagnosis procedure following items must be checked:
1. Inspect all exposed cables for damage or abrasion.
2. Check ground on ABS system.
3. Battery - state of charge.
4. Check hub end-float.
5. All ABS fuses and electrical connections.
Fault rectification
1. Complete harness should be replaced if faults are found in wiring harness.
2. DO NOT use unspecified cables or connectors, as this could jeopardise safe function of ABS.
3. DO NOT attempt to open sealed 35 way connector to ECU.
FAULT DIAGNOSIS PROCEDURE
NOTE: If ABS warning light illuminates due to large sensor air gap, fault will be retained by the ECU memory. Where wheel sensors have been pushed fully home prior to
test, The ECU will indicate a fault that has been rectified.
NOTE: After any steering adjustment, bearing replacement/adjustment, brake disc replacement: Check hub end-float and sensor clearance.
