1) Disconnect the connector from the VDCCM&H/U.
2) Measure the resistance between VDCCM&H/U and steering angel sensor.
Connector & terminal
(B231) No. 1 — (B310) No. 10:
(B231) No. 2 — (B310) No. 35:
Is the resistance less than 0.5 Ω?
Repair the harness between the steering angle sensor and VDCCM&H/U.
