DTC IS ACTIVE

1. Start the engine and allow it to reach normal operating temperature.

WARNING:

When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the
pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in
possible serious or fatal injury.

2. With the scan tool, select View DTCs.
