Circuit/System Verification

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: If the suspect gauge is the speedometer, the drive wheels of the vehicle must be raised and the transmission must be placed in drive or first gear. Refer to Lifting and Jacking the Vehicle .
  1. Ignition ON and the scan tool installed, perform the IPC Gauge Sweep Test in the IPC Output Controls. Verify that all gauge dials move from minimum to the maximum value and back to the gauge minimum value.
    • If the gauges do not perform the IPC Gauge Sweep Test, replace the IPC.
  2. Start the engine with the vehicle drive wheels raised and place the transmission in drive or first gear. Verify that the speedometer value matches the scan tool Vehicle Speed parameter in the ECM Engine Data List.
    • If the speedometer is incorrect, test or replace the IPC.
