Brakes - DSC Lamp ON/ABS Noise When Cornering

SECTION: 206-07
ABS Noise During Cornering
AFFECTED VEHICLE RANGE:
Range Rover (LM)
VIN 6A198058 to 6A214897
CONDITION SUMMARY:
NOISE FROM THE ABS SYSTEM
NOTE:
Normal DSC will provide a DSC warning lamp and ABS noise when cornering forces are high and steering inputs are large. The driver would expect
to be near cornering limits of the vehicle in these conditions.
A customer may report a concern that very intermittently when cornering at low speeds or cornering on a large radius at higher speed with low cornering
forces (when DSC intervention would not be expected) a noise is coming from the Anti-Lock Braking System (ABS), and the Dynamic Stability Control
(DSC) warning lamp illuminates.
Cause:
The ABS yaw rate tune is too sensitive.
Action:
Should a customer express concern with the above symptoms, a new-specification ABS modulator unit is to be installed. Follow the Repair Procedure
outlined in this bulletin.
