Instrument Panel Cluster
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
If all of the Instrument Panel Cluster (IPC) gauges and indicators are inoperative, always check the instrument IPC fused B(+) fuses and the IPC fused B(+) and ground circuits for shorts or opens. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to STANDARD PROCEDURE . and. Refer to REMOVAL . Refer to INSTALLATION .
The IPC used in this vehicle needs to be loaded with factory configured PROXI in order for the IPC to be compatible with features and optional equipment in the vehicle in which they are initially installed. The IPC is programmed to do this by embedding the Vehicle Identification Number (VIN) and other information critical to proper IPC operation into electronic memory. This embedded information is learned through electronic messages received from other electronic modules in the vehicle over the Controller Area Network (CAN) data bus, and through certain hard wired inputs received when the IPC is connected to the vehicle electrically. Once configured, the IPC memory may be irreparably damaged and certain irreversible configuration errors may occur if the IPC is connected electrically to another vehicle; or, if an electronic module from another vehicle is connected that provides data to the IPC (including odometer values) that conflicts with that which was previously learned and stored. Therefore, the practice of exchanging (swapping) IPCs and other electronic modules in this vehicle with those removed from another vehicle must always be avoided. Failure to observe this caution may result in IPC damage, which is not reimbursable under the terms of the product warranty. Service replacement IPCs are provided with the correct VIN, and the certified odometer and engine hours values embedded into IPC memory, but will otherwise be automatically configured for compatibility with the features and optional equipment in the vehicle in which they are initially installed.
Certain indicators in this IPC are automatically configured. This feature allows those indicators to be activated or deactivated for compatibility with certain optional equipment. If the problem being diagnosed involves improper illumination of the cruise indicator, the electronic throttle control indicator, the fog lamp indicator, any of the four-wheel drive indicators, the overdrive OFF indicator, the tow/haul indicator, the transmission over-temperature indicator, the security indicator or the gear selector indicator, disconnect and isolate the negative battery cable(s). Refer to BATTERY DISCONNECT AND CONNECT - 3.6L or BATTERY DISCONNECT AND CONNECT - 5.7L . After about five minutes, connect the negative battery cable(s) and turn the ignition ON. Refer to BATTERY DISCONNECT AND CONNECT - 3.6L or BATTERY DISCONNECT AND CONNECT - 5.7L . The IPC should automatically relearn the equipment in the vehicle and properly configure the configurable indicators accordingly.
