Pinpoint Test J: 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 anti-theft 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 anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or START position. 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.

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). A low battery voltage can cause the PATS to allow the eCVT to crank the engine, but can keep the fuel injectors from operating. Also, a key read concern can keep the fuel injectors from operating, while a TCM-PCM ID concern can be at fault if there is no starter operation, although a key read concern can also be the cause of an inoperative eCVT (starter). 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 IC.

This pinpoint test is intended to diagnose the following:

- Starting system concern
- PATS concern



PINPOINT TEST J: THE VEHICLE DOES NOT START

-------------------------------------------------
J1 CHECK FOR COMMUNICATION WITH THE TRANSMISSION CONTROL MODULE (TCM) AND IC


- Connect the scan tool.
- Ignition ON.
- Carry out the network test using the scan tool.
- Does the scan tool establish communication with the TCM and the IC?

Yes
GO to J2.

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

-------------------------------------------------
J2 CHECK FOR IC DTCs


- Retrieve the IC continuous and on-demand DTCs.
- Are any IC DTCs present?

Yes
REFER to DTC Charts.

No
The no-start condition is not PATS-related. REFER to Computers and Control Systems Information to diagnose the cause of the no-start condition.
