EPS Indicator Does Not Go Off
Diagnostic Procedure
NOTE:
If any of the CAN communication failure DTC is indicated in other system, troubleshoot the DTC first.
- Check for open wire or short wire in the F-CAN circuit;
- Between the gauge control module and the CAN gateway (F-CAN D_H, F-CAN D_L).
- Between the EPS control unit and the CAN gateway (F-CAN C_H, F-CAN C_L).
- Check the EPS control unit power circuit (+B_EPS(70A)/+B_EPS, IG1_VSA(VST)).
- Check the EPS control unit ground circuit (GND).
- Do the gauge control module self-diagnostic function .
