Passive Anti-Theft System (PATS) - Inspection and Verification
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
A new instrument cluster must be reconfigured after installation. Refer to
MODULE CONFIGURATION
.
NOTE:
When a new instrument cluster is installed, the new instrument cluster must be mated to the powertrain control module (PCM) by carrying out a parameter reset. For additional information, refer to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET .
NOTE:
The keys must be programmed into the new instrument cluster. For additional information, refer to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . If parameter reset and key programming are not carried out, a no start condition may occur.
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.VISUAL INSPECTION CHART
Mechanical Electrical - Large metallic objects, a second passive anti-theft system (PATS) key on the same key ring as the PATS key, or electronic devices on the key chain that can be used to purchase gasoline or similar items
- Ignition lock cylinder
- PATS key
- Use of a non-PATS key
- More than one PATS key on the customer's key chain
- Smart junction box (SJB) fuse(s):
- 13 (7.5A)
- 23 (7.5A)
- 26 (7.5A)
- Instrument cluster
- PATS transceiver
- Ignition switch
- Loose or corroded connection(s)
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- Check that the program card is correctly installed.
- Check the connections to the vehicle.
- Check the ignition switch position.
- If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for instrument cluster, refer to INSTRUMENT CLUSTER .
- No response/not equipped for PCM, refer to the MODULE COMMUNICATIONS NETWORK .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the instrument cluster and the PCM.
- If DTCs related to the concern are retrieved, go to the PASSIVE ANTI-THEFT SYSTEM (PATS) - DIAGNOSTIC TROUBLE CODES (DTC) INDEX .
- If no DTCs related to the concern are retrieved, go to the PASSIVE ANTI-THEFT SYSTEM (PATS) - SYMPTOM CHART .
