Remove the instrument panel (see page 20-75), then remove the upper column cover (see page 17-9). Remove the screws from the gauge assembly (A). Disconnect the connectors (B) and remove the gauge assembly. Install the gauge assembly in the reverse order of removal.

Before testing, check the No. 9 (10A) fuse in the under-hood fuse/relay box and No. 10 (7.5A) fuse in the under-dash fuse/relay box. Start the engine and check the Malfunction Indicator Lamp (MIL). Does the MIL come on? YES – Troubleshoot the DTC (see page 11-90) and recheck. NO – Go to step 2. Check the multiplex control unit DTC (see page 22-273). Is the DTC indicated? YES – Troubleshoot the DTC (see page 22-273) and recheck. NO – Inspect the connector and socket terminals of the gauge assembly connectors. If the terminals look OK, replace the gauge assembly.
