Land Rover Discovery (2009–2016) Service Manual / Chassis / Chassis-Brake-System / Anti-lock Control - Traction Control / Diagnosis and Testing

PRINCIPLES OF OPERATION

For a detailed description of the Anti-lock Brake System, refer to the relevant Description and Operation section in the workshop manual. REFER to: Anti-Lock Control - Traction Control (206-09B Anti-Lock Control - Traction Control, Description and Operation).

INSPECTION AND VERIFICATION

CAUTION:

Diagnosis by substitution from a donor vehicle is NOT acceptable.

Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTES:

  • If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module/component.
  • When performing voltage or resistance tests, always use a digital multimeter that has the resolution ability to view 3 decimal places.

    For example, on the 2 volts range can measure 1mV or 2 K Ohm range can measure 1 Ohm. When testing resistance always take the resistance of the digital multimeter leads into account.

  • Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
  1. Verify the customer concern
  2. Visually inspect for obvious signs of damage and system integrity

Visual Inspection

Visual Inspection

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
