Scan Tool Usage

Refer to the Scan Tool for complete information on scan tool diagnostics.

Lamp Test
In order to do a lamp test, you must use the scan tool and be in the Instrument Panel Cluster Special Functions. Then go to WOW mode, in this mode you can turn all the indicators ON and OFF.
The Low Tire Warning indicator is just one of many indicators that can be turned ON and OFF in the WOW Mode.
The WOW Test aids in diagnosing indicator malfunctions. The test allows the operator to flash the all the indicators on and off.

Automated Test
