Steering Angle Sensor

Steering Angle Sensor

The steering angle sensor (C0862) receives a constant battery feed from fuse 13 of the passenger compartment fuse box (C0586) on an RG wire, and a feed from the energised ECM relay (C1895) via fuse 51 of the passenger compartment fuse box (C0584) on an RW wire. The sensor (C0862) is earthed on an NB wire.

The steering angle sensor (C0862) transmits steering angle and rate of steering messages via the Can bus on YN (low) and YB (high) wires. These signals are created by two potentiometers located within the sensor. The ABS ECU uses these messages to enable the DSC system control lateral stability.

Brake Fluid Level Warning Switch

If the brake fluid level is below the minimum level, DSC operation is suspended. The ABS ECU (C0506) monitors the condition of the brake fluid level switch (C0026) via an NGY wire.

HDC

The HDC switch (C0365) is mounted on the side of the gear selector lever, and is provided an auxiliary ignition feed from fuse 35 of the passenger compartment fuse box (C0587) on a GBY wire. The ABS ECU (C0506) monitors the condition of the HDC switch (C0365) via a BG wire.

EBA Brake Pedal Switch

The brake pedal switch (C0075) is provided an auxiliary ignition feed from fuse 9 of the passenger compartment fuse box (C0587) on a PY wire. The ABS ECU (C0506) monitors the condition of the brake pedal switch (C0075) on a UR wire to enable it to operate its Emergency Brake Assist (EBA) function.

Diagnostic Socket

The diagnostic socket is located behind an access panel on the drivers side of the fascia. The ABS ECU (C0506) and the steering angle sensor (C0862) can be interrogated by T4 via the K line bus on WP wires.
