TOPix - SSM71278 - Vehicle Steering Feels Heavier than expected Reference SSM71278 Models Discovery Sport/ LSS0 Page 1 of 2 Range Rover/ L405 Range Rover Evoque / L538 Range Rover Sport/ L494 Title Vehicle Steering Feels Heavier than expected Category Chassis Last modified 03-Feb-2016 00:00:00 Symptom 303000 Steering/Handling Attachments 1111 Ground Points.pdf (1111 Ground Points.pdf) Content Issue: A customer may report the vehicle steering feels heavy potentially accompanied by visual or audible warnings through the instrument pack. The following DTCs may also be logged: EPAS DTCs logged: -B1304-16: Electronic Power Assisted Steering (EPAS) system circuit voltage below threshold -U3001-00: Power Steering Control Module (PSCM) system improper shutdown. These may be accompanied by: -U0001-87 I 88 High speed CAN bus invalid serial data received / missing message. CHCM DTCs logged: -U0131-00 Chassis Control Module (CHCM) lost comms with PSCM. -U3003-62 Battery voltage signal compare failure. -U0420-68 CHCM invalid data received from PSCM. -B1304-04 Electronic Power Assisted Steering System - System Internal Failures Cause: This may be caused by: -Low battery voltage. -Wiring harness issue (short I open circuit, high resistance). -High resistance at EPAS earth terminal (for L405/L494) G1D132 and or G4D178, (see attached diagram). Or if on L550/L538 high resistance at G1 D122A, G1 D122B, G1D122AZ and G1D108. -Poor connection or pin set condition at connector number: C11-G1 Action: -Using SDD please check the CHCM and EPAS for any DTC -Confirm the vehicle battery condition is OK -Confirm ignition and main feed fuses are secure. http://topix. landrover.j lrext. com/top ix/service/archive/617371 /index 3/1/2016 TOPix - SSM71278 - Vehicle Steering Feels Heavier than expected Page 2 of 2 -Check and clean the following earth terminals L405/L494:G1D132 & G4D178 L550/L538: G1D122A, G1D122B, G1D122AZ and G1 D108. Replace the washer if found to be corroded and re-tighten retaining fixings. -Refer to the electrical circuit diagrams (211.02 in TOP Ix) and check the power steering control module power feed circuit for short circuit to ground, open circuit, high resistance. -Disconnect C11-G1 and confirm pin condition with a pin drag test. Ensure when reconnecting that it has securely latched http://topix. landrover.j lrext. com/top ix/service/archive/617371 /index 3/1/2016
