Anti-Theft Indicator

WARNING: This page is about a different variant/trim than selected.

The PATS on the hybrid uses a visual anti-theft indicator located in the IC. The anti-theft indicator proves out for 3 seconds when the ignition key is in the ON or START position under normal operation. If there is a PATS concern, this indicator either flashes rapidly or glows steadily when the ignition key is turned to the ON or START position. PATS also flashes the anti-theft indicator every 2 seconds when the ignition key is in the OFF position to act as a visual theft deterrent. Retrieve DTCs from the IC and the TCM to determine if there are any PATS-related DTCs that can indicate the cause of the no-start. Refer to the SYMPTOM CHART .

PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS does not disable a running vehicle.

A PATS no-start can involve a vehicle no-start due to either the fuel injectors not operating or the Electronically Controlled Continuously Variable Transmission (eCVT) not cranking the engine (or both). If the PATS anti-theft indicator does not prove out and one (or both) of the previous conditions are present, it can be due to a PATS concern. If the anti-theft indicator proves out, and the vehicle does not start, it is probably not a PATS concern. Refer to the INTRODUCTION - GASOLINE MODELS . If the anti-theft indicator does not illuminate at all, it can be an IC concern. A low battery voltage can cause the PATS to allow the eCVT to crank the engine, but can keep the fuel injectors from operating.
