Steering Angle Sensor Initialization Incomplete (C1439,C1445)
DESCRIPTION The skid control ECU (brake booster with master cylinder assembly) acquires the steering sensor zero point every time the power switch is turned on (IG) and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores previous zero points. DTCs C1439
