Brake Warning Indicator The brake warning indicator is illuminated for a 3 second bulb check when the ignition is turned to position II. The indicator will also illuminate if the parking brake is on, or the brake fluid falls below a pre-determined level. The instrument cluster is hardwired to the parking brake switch and the brake fluid level switch, which are connected in parallel. If either of the conditions above are met a ground path is created, illuminating the indicator. Side Lights On Indicator The side lights on indicator is controlled by the lighting switch. When the lighting switch is turned to the side or headlamp position, a hardwired feed is provided to the instrument cluster via the CJB. On receipt of the hardwired feed, the instrument cluster illuminates the indicator. Anti-theft Alarm Indicator Illumination of the anti-theft alarm indicator is controlled directly by the anti-theft alarm control module. For additional information, refer to: Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation), Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation). Transfer Box Low Range Indicator The transfer box high/low range switch is hardwired to the instrument cluster. When low range is selected, the transfer box provides a feed to instrument cluster, which subsequently illuminates the green low range indicator. The low range indicator remains permanently illuminated until high range is selected and the feed from the high/low range switch is removed. Ignition/No Charge Warning Indicator The ignition/no charge indicator is controlled by the instrument cluster software and illuminated on receipt of a high speed CAN bus message from the ECM. The indicator illuminates in a red color when the ignition is turned to position II and is extinguished when the engine is started. If the indicator remains illuminated after the engine has started or illuminates when driving, the alternator charge output has failed. Low Oil Pressure Warning Indicator The low oil pressure indicator is controlled by the instrument cluster software and illuminated on receipt of a high speed CAN bus message from the ECM. The indicator is illuminated in a red color when the ignition switch is turned to position II. When the engine is started and the oil pressure increases the low oil pressure indicator should extinguish. If the indicator remains illuminated or illuminates when driving the vehicle should be stopped at the earliest opportunity and the engine switched off until the fault is rectified. Instrument Cluster Replacement If a new instrument cluster is to be fitted, the Land Rover approved diagnostic system must be connected to the vehicle and the instrument cluster renewal procedure run. This will ensure that vehicle coding data is correctly installed in the new instrument cluster. The Land Rover approved diagnostic system will also record the current service interval data and restore the settings to the new instrument cluster. |
