Test F: The Anti-Theft Indicator Is Always/Never On
2008 Mercury Mariner 2WD V6-3.0LSECTION Test F: The Anti-Theft Indicator Is Always/Never On
PINPOINT TEST F: THE ANTI-THEFT INDICATOR IS ALWAYS/NEVER ON
Normal Operation
The passive anti-theft system (PATS) uses a visual anti-theft indicator located in the instrument cluster. This indicator proves out for 3 seconds when the key is turned to the ON or START position under normal operation. If there is a PATS concern, this indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or the START position. PATS also flashes the anti-theft indicator every 2 seconds at key off to act as a visual theft deterrent. The anti-theft indicator operation is controlled by the instrument cluster.
This pinpoint test is intended to diagnose the following:
- Instrument cluster
