Inspection and Verification

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: When using a remote starter switch or jumper wire, be sure the ignition switch is in the OFF position and the transmission is in PARK with the parking brake control fully applied.

WARNING: When working underhood in the vicinity of the starter motor, be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times. A protective cap or boot is provided over the terminal of this lead and must be reinstalled after repairing.

CAUTION: When working in the area of the starter motor, be careful to avoid touching hot exhaust components.

NOTE: When working on the starter system, make sure the anti-theft system is operational.

Verify the customer concern by operating the starting system to duplicate the conditions.

Inspect to determine if any of the following mechanical or electrical concerns apply.

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:
- [appropriate communication networks, such as SCP, ISO, UBP, CAN] circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for generic electronic module (GEM), refer to MULTIFUNCTION ELECTRONIC MODULES .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the GEM.
If the DTCs retrieved are related to the concern, go to PASSIVE ANTI-THEFT SYSTEM (PATS) - DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
If not DTCs related to the concern are retrieved, GO to SYMPTOM CHART .

PASSIVE ANTI-THEFT SYSTEM (PATS) - DIAGNOSTIC TROUBLE CODE (DTC) INDEX

DTC	Description	Source	Action
B1213	Anti-Theft Number of Programmed Keys is Below Minimum	Powertrain Control Module (PCM)	REFER to ANTI-THEFT - PATS .
B1232	Transceiver Module Antenna Failure. Memory Failure in the PCM	PCM	REFER to ANTI-THEFT - PATS .
B1342	ECU is Defective	PCM	CLEAR the DTCs. REPEAT the self-test. If DTC B1342 is retrieved again, INSTALL a PCM. REFER to ELECTRONIC ENGINE CONTROLS - 2.3L , ELECTRONIC ENGINE CONTROLS - 3.0L (4V) or ELECTRONIC ENGINE CONTROLS - HYBRID . CLEAR the DTCs. REPEAT the self-test.
B1600	Passive Anti-Theft System (PATS) Key Transponder is Not Received	PCM	REFER to ANTI-THEFT - PATS .
B1601	PATS Received Incorrect Key-Code From Key Transponder	PCM	REFER to ANTI-THEFT - PATS .
B1602	PATS Received Invalid Format of Key-Code From Key Transponder	PCM	REFER to ANTI-THEFT - PATS .
B1681	PATS Transceiver Module Signal is Not Received	PCM	REFER to ANTI-THEFT - PATS .
B2103	Antenna Not Connected	PCM	REFER to ANTI-THEFT - PATS .
B2431	Key Program Failure (Defective Key or Transceiver)	PCM	VERIFY if the correct PATS key is being used. If the PATS key is defective, USE a new key for programming.
