Diagnostic Aids

DTC U0102:00 indicates a possible failure of the HS-CAN which can be due to a circuit fault in the HS-CAN, the PSCM wiring harness or a TCCM concern.

Do not install a new PSCM as part of the repair for a PSCM DTC U0102:00.

When the selectable drive mode is changed, the PSCM modifies the steering characteristics of the EPAS system. The presence of this DTC prevents the selectable drive mode system (if equipped) from activating. If set while the vehicle is in a drive mode other than NORMAL, the PSCM defaults to NORMAL and the system is disabled.
