    • If any DTC is set, diagnose this first.
  2. Ignition ON, perform the Instrument Cluster Gauge Sweep test with the scan tool, verify that all gauges sweep from their low to high position.
    • If any gauge does not sweep, replace the P16 Instrument Cluster.

    • If the values do not match, replace the P16 Instrument Cluster.
