Diagnostic Aids

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

If the condition is not present, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Review the Freeze/Failure Records vehicle mileage since the diagnostic test failed. This may help determine how often the condition that caused the DTC to be set occurs.
Allow engine coolant temperature to drop below 80°C (176°F).
Set the A/C to the OFF position.
Once the ECM has enabled a low or high fan speed, that speed must run for a minimum of 20 seconds.
