1 Published: Dec 17, 2007 Instrument Cluster Overview Data is provided to the instrument cluster from other subsystem modules in the form of controller area network (CAN) s. The instrument cluster identifies the signals and displays the appropriate in the center. Most s are accompanied by a chime or series of chimes which are requested by the module generating the. The driver can view system status s which are current within the instrument cluster software by pressing and holding the trip reset button for more than three seconds, the information display will then display the current s in priority order. For more information, refer to the relevant workshop manual section. Car configuration file (CCF) CAUTION: If a new instrument cluster is to be installed, the instrument cluster renewal procedure must be carried out using the approved diagnostic system. This will ensure that the CCF data is correctly transferred from the central junction box (CJB) to the replacement cluster. The CCF will also need to be updated using the approved diagnostic system if the vehicle is modified in service from its original factory specification. This can include the fitting of non-standard wheels and/or tires and optional accessory dealer install components with an electrical interface, such as park distance control. The CCF contains all relevant data about the specification and market condition of the applicable vehicle, immobilization codes and driver personal settings. This information is retained in the CJB, the engine control module (ECM) and the instrument cluster enabling each system module to detect which systems and components are installed to the vehicle. The information is continuously transferred between these three system modules to ensure that the data is constantly backed-up between the modules. Inspection and Verification 1. Verify the customer concern. 2. Confirm which, if any, warning lights and/or s were displayed on the instrument cluster. For a list of s, refer to workshop manual section Information and Message Center. 3. Visually inspect for obvious electrical faults.

If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. 5. Use the approved diagnostic system or a scan tool to retrieve any DTCs before moving onto the DTC index. Make sure that all DTCs are cleared following rectification. landrovertechinfo.com/ /frmviewit.js 1/5

2 DTC index NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system). DTC Description Possible cause(s) Action B1A0016 Battery voltage low Battery ground cable high Battery connections loose/corroded Battery current drain Check the battery condition and state of charge. Refer to the relevant section of the workshop manual. Check the module power and ground circuits. Refer to the electrical guides. B1A0017 Control module circuit voltage above threshold Battery voltage high (overcharging) Control module circuit Short circuit to power Check the battery condition and state of charge.
