DTC Set Condition

WARNING: This page is about a different variant/trim than selected.

WCM receives the wheel speed information from ASC-ECU via the CAN-bus line. Although WCM receives the information that the wheel is not currently rotated from ASC-ECU, if the TPMS transmitter sends the information that the wheel is rotated, this code is set.
