Water Ingress into ABS Modulator
Connector
AFFECTED VEHICLE RANGE:
Range Rover (LM) Up to 4A161678
SITUATION:
ABS/HDC WARNING LIGHT ILLUMINATION
Water can enter the ABS modulator connection through the ground eyelet crimp under sustained usage in conditions of high water, particularly fording
streams. The water ingress problem is more prevalent when the engine bay is hot. Water contamination can result in connector terminal corrosion and the
ABS/HDC warning light being displayed on the instrument pack.
RESOLUTION:
INSTALL NEW-SPECIFICATION GROUND WIRES OR CONNECTOR HARNESS
Should a customer express concern regarding the above, refer to the procedure in this TIB. Inspect the connector for corrosion and replace either the
ground leads and eyelet with a new set or if indicated the entire connector with a repair connector harness. The new configuration ground leads have a
crimp sealed ground eyelet.
