Anti-Theft

Pinpoint Test H: The Vehicle Does Not Start

Normal Operation

The Passive Anti-Theft System (PATS) uses a visual anti-theft indicator located in the Instrument Cluster (IC). 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 (Passive Anti-Theft System) 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. If there is no PATS (Passive Anti-Theft System) concern, the anti-theft indicator is off. PATS (Passive Anti-Theft System) 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 IC (Instrument Cluster).

This pinpoint test is intended to diagnose the following:

- Starting system concern

- PATS (Passive Anti-Theft System) concern

PINPOINT TEST H : THE VEHICLE DOES NOT START

H1 CHECK FOR COMMUNICATION WITH THE PCM AND IC (Instrument Cluster)

- Connect the scan tool.

- Ignition ON.

- Carry out the network test using the scan tool.

Does the scan tool establish communication with the PCM and the IC (Instrument Cluster)?

Yes
GO to H2.

No
REFER to Information Bus to diagnose the module that is not communicating with the scan tool.

H2 CHECK FOR IC (Instrument Cluster) DTCs

- Retrieve the IC (Instrument Cluster) continuous and on-demand DTCs.

Are any IC (Instrument Cluster) DTCs present?

Yes
REFER to DTC Charts. Antitheft and Alarm Systems

No
The no-start condition is not PATS (Passive Anti-Theft System) -related. REFER to Computers and Control Systems Information to diagnose the cause of the no-start condition.
