Parking Aid System Ford Econoline E250

SPECIFICATIONS

GENERAL SPECIFICATIONS

The parking aid system consists of the following

1. Four ultrasonic parking aid sensors (located in the rear bumper cover)
2. Parking Aid Module (PAM) (located behind the engine cover mounted to the instrument panel frame)
3. Parking aid speaker (located on the PAM)
4. Parking aid disable feature (integral to the Instrument Panel Cluster (IPC) message center)

The parking aid system calculates the distance to an object around the rear of the vehicle by the use of 4 ultrasonic sensors. The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper when REVERSE (R) is selected.

The rear sensors are activated when REVERSE (R) is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves slowly in reverse at speeds of less than 4.8 km/h (3 mph). The parking aid system may not detect moving objects.

Video

The rear video camera system consists of the following

1. Video camera (located in the license plate housing in the rear door)
2. Auto-dimming interior mirror (without navigation)
3. Audio Control Module (ACM) (with navigation)

For vehicles without navigation, the image from the video camera is displayed in the left portion of the auto-dimming interior mirror. For vehicles with navigation, the image from the video camera is displayed in the ACM. The displayed video image is horizontally inverted from that viewed from the video camera perspective to mimic a conventional mirror image.

Principles of Operation

Note. The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The parking aid system detects objects behind the vehicle when the REVERSE (R) gear is selected. The Parking Aid Module (PAM) calculates the distance to an object by the use of 4 ultrasonic sensors mounted in the rear bumper. The PAM does this by calculating the distance to an object within the 170 degree semicircular area around the rear of the vehicle.

A variable-rate warning tone is generated from a speaker attached to the PAM. The speaker increases its warning tone rate as the vehicle gets closer to an obstacle. When an object is detected within 30 cm (12 in) of the sensors, the warning tone becomes continuous.

The parking aid system is enabled when the ignition switch is in the RUN position and the REVERSE (R) gear is selected. The parking aid system is disabled if a fault is detected in the sensors, the parking aid speaker, or the PAM. This is indicated by a parking aid disabled warning message in the message center.

The PAM is on the Medium Speed Controller Area Network (MS-CAN) and can be diagnosed with a scan tool. The PAM communicates with the scan tool, the SJB, the Audio Control Module (ACM) and the Instrument Panel Cluster (IPC).

Note. Both the MS-CAN and the High Speed Controller Area Network (HS-CAN) are used for intermodule communication. A gateway message is transferred from one network to another network through the IPC. Refer to MODULE COMMUNICATIONS NETWORK for additional network communication information.

Note. The rear door must be closed for correct operation of the video camera system.

Note. The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The rear video camera system is used to assist the driver while reversing or parking the vehicle. The video camera is located in the center of the right rear door mounted to the license plate housing. For vehicles without navigation, the image of the area behind the vehicle is displayed in the left portion of the auto-dimming interior mirror. For vehicles with navigation, the image of the area behind the vehicle is displayed in the Audio Control Module (ACM). A dashed line on the displayed image represents the center of the vehicle and 3 color-coded lines (red, yellow, green) identify different zones between the rear of the vehicle and objects.

Note. The color-coded lines may not indicate accurate or consistent distances between objects located behind the vehicle and the rear of the vehicle. This normal condition is due to variances in vehicle ride height, including, but not limited to, vehicle loading.

For vehicles without navigation, the signal from the rear video camera is sent to the auto-dimming interior mirror display on a pair of shielded video circuits.

For vehicles with navigation, the signal from the rear video camera is sent to the ACM on a pair of shielded video circuits. The displayed video image is horizontally inverted from that viewed from the video camera perspective to mimic a conventional mirror image.

The rear video camera system is active with the ignition in RUN and the transmission selector in the REVERSE (R) position. The video system has a delay feature (vehicles with navigation) that keeps the image displayed for a period of time depending on what type of display unit is available on the vehicle.

For vehicles equipped with navigation, the image can be displayed in the ACM until the vehicle reaches 8 km/h (5 mph) when in DRIVE (D) after shifting out of REVERSE (R) gear. The image cannot be displayed if the vehicle is shifted into PARK (P).

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.

Refer to «MODULE COMMUNICATIONS NETWORK»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network) to diagnose no response from the PCM.
7. Carry out the network test. If the scan tool responds with no communication for one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network) . If the network passes, retrieve and record the continuous memory DTCs.
8. Clear the continuous DTCs and carry out the self-test diagnostics for the ACM.
9. If the DTCs retrieved are related to the concern, go to «DTC CHARTS»(/ford/econoline-e250/2012-2013/remont/collisionavoidance/#parking-aid-system) . For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in «MULTIFUNCTION ELECTRONIC MODULES»(/ford/econoline-e250/2012-2013/remont/cruise-control-systems/#multifunction-electronic-modules) .
10. If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(/ford/econoline-e250/2012-2013/remont/collisionavoidance/#parking-aid-system) .

Note. This module utilizes a 5-character DTC followed by a 2-character failure-type code.
