Pinpoint Test Z: The Anti-Theft Indicator Is Never/Always On
Normal Operation
The Passive Anti-Theft System (PATS) indicator proves out for 3 seconds when the key is turned to the RUN or START position under normal operation. If there is a PATS concern, the anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the RUN or the START position. The 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 (IC)
NOTE: If DTC U0100 is set in the IC, other observable symptoms may be an inoperative speedometer, tachometer or odometer.
This pinpoint test is intended to diagnose the following:
- PATS concern
- IC
