Range Rover Evoque: Electric Power Assisted Steering Module (EPAS)
Steering Gear (PSCM)
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 the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a new module/component.
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Steering Gear, for additional Diagnosis and Testing information refer to the relevant Diagnosis and Testing Section.
For additional information, refer to: Power Steering (211-02 Power Steering, Diagnosis and Testing).
