Anti-Theft - Without Intelligent Access (IA)

Pinpoint Test E: The Engine Does Not Start

Normal Operation

The Passive Anti-Theft System (PATS) disables the engine from starting by disabling the fuel injectors and starter. When the ignition is turned to the RUN or START position, the PATS (Passive Anti-Theft System) reads the PATS (Passive Anti-Theft System) key and checks the PCM ID. If an unprogrammed PATS (Passive Anti-Theft System) key is used or an invalid PCM ID is received, the PATS (Passive Anti-Theft System) disables the engine. If there is a PATS (Passive Anti-Theft System) concern that caused the engine to be disabled, the anti-theft indicator flashes in the Instrument Panel Cluster (IPC).

This pinpoint test is intended to diagnose the following:

- Driveability concern

- PATS (Passive Anti-Theft System) concern

- Starting system concern

PINPOINT TEST E : THE ENGINE DOES NOT START

E1 CHECK FOR COMMUNICATION WITH THE PCM AND THE IPC (Instrument Panel Cluster)

- Carry out the network test using the scan tool.

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

Yes
GO to E2.

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

E2 CHECK FOR PATS DTCs

- Enter the following diagnostic mode on the scan tool: IPC (Instrument Panel Cluster) Self-Test.

- Enter the following diagnostic mode on the scan tool: PCM Self-Test.

Are any PATS (Passive Anti-Theft System) DTCs present?

Yes
REFER to the DTC Charts Anti-Theft - Without Intelligent Access (IA).

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