Warning Lamps (page 2 of 4)

Illumination of the Traction Control (TC) warning lamp (C0230) is controlled by the ABS ECU (C0504) on a YS wire. When TC is active (or if the ABS ECU detects a TC fault) the ABS ECU provides an earth path, allowing current from fuse 15 of the passenger compartment fuse box (C0580) to flow across the bulb. Illumination of the handbrake/low brake fluid level warning lamp (C0230) is controlled by the brake fluid level switch (C1725 on LHD, C0026 on RHD), and the handbrake switch (C0091).

If brake fluid level is too low, the brake fluid level switch contacts (C1726 on LHD, C0031 on RHD) will close, creating an earth path for the bulb on a B wire.

If the handbrake is applied, the switch contacts (C0091) close creating an earth path for the bulb.

NOTE: If ABS isn't fitted, a shorting link is fitted to the instrument pack between C0234–9 and C0234–13. This enables the handbrake/low brake fluid warning lamp to operate correctly in the absence of an EBD signal. Illumination of the main beam warning lamp (C0233) is controlled via the column switch (C1739 on LHD, C1042 on RHD) on a UW wire. The lamp (C0230) is earthed on a B wire. For more information, refer to the Head, Side and Tail Lamps section of this manual.  HEAD, SIDE AND TAIL LAMPS. Illumination of the RH direction indicator warning lamp (C0233) is controlled via the column switch (C1739 on LHD, C1040 on RHD) on a GW wire. The lamp (C0230) is earthed on a B wire. For more information, refer to the Direction Indicator/Hazard Warning Lamps section of this manual.  DIRECTION INDICATOR/HAZARD WARNING LAMPS. Illumination of the rear fog lamp warning lamp (C0233) is controlled by the fog lamp ECU (C1724 on LHD, C0543 on RHD) on a RY wire. The lamp (C0230) is earthed on a B wire. For more information, refer to the Fog Lamps section of this manual.  FOG LAMPS. Illumination of the hazard warning lamp (C0233) is controlled by the hazard warning relay (C0547) on a BR wire. The lamp (C0230) is earthed on a B wire. For more information, refer to the Direction Indicator/Hazard Warning Lamps section of this manual.  DIRECTION INDICATOR/HAZARD WARNING LAMPS.
