Parking Aid System: Diagnosis Ford Mustang V рестайлинг 2

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Body Control Module (BCM) fuse 32 (10A) Wiring, terminals or connectors Parking aid sensors
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. NOTE: Make sure to use the latest scan tool software release. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM. If the scan tool does not communicate with the vehicle: Verify the ignition is ON. The air bag warning indicator prove-out confirms ignition ON (other indicators may NOT prove ignition is ON) confirms ignition ON. If ignition does not turn ON, refer to «STEERING COLUMN SWITCHES»(ref-574137) to diagnose no power in RUN. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-574111) , Inspection and Verification to establish a scan tool session.
6. NOTE: The ignition must be OFF to carry out the Remote Function Actuator (RFA) module self-test. Carry out the self-test diagnostics for the RFA module and Parking Aid Module (PAM).
7. If the DTCs retrieved are related to the concern, go to «DTC CHARTS»(ref-574192-S24823954902013082300000) . For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in «MULTIFUNCTION ELECTRONIC MODULES»(ref-574135) .

Note. The object used in this system check can be fabricated from 9 cm O.D. (3 in I.D) plastic pipe 100 cm (39 in) in length (available as Polyvinyl Chloride (PVC) pipe, or similar from a hardware or plumbing supply).

Note. The following system check should be carried out with the vehicle on a level surface. The specified object locations are approximate, not absolute

Note. The parking aid system defaults to on when the ignition key is cycled from OFF to ON.

Note. The scan tool may be used to monitor distance PIDs. The distance PIDs read between 0 and 255 cm (0 and 8 ft) on a correctly functioning system.

1. Turn the ignition to the ON position, engine off.
2. Set the parking brake on.
3. Place the gear shift in REVERSE (R).
4. Verify that the parking aid system detects the specified object when placed within the 5 specified locations (P1, P2, P3, P4, P5). The pipe should be inside of these locations. The speaker should beep slowly when objects are detected on the outer edges of the detection zone, and increase as the object is moved closer to the vehicle. When the object is within 46 cm (18 in) of the rear bumper, the sounder should be on continuously. If the Parking Aid Module (PAM) does not detect the object above, refer to «PARKING AID»(ref-574192-S24110980932013082300000) .
