Parking assistance — diagnostics and checks (vehicles after 10.2001)

Inspection and verification

1. Check the customer's complaint.

2. Visually inspect for obvious signs of electrical damage.

Visual Inspection Table

Electrical factors:

• Fuse (And)
• Relay
• Wiring harness
• electrical connector (s)
• Sensor (And) parking assistance systems
• Parking assistance display and speaker
• Reversing light switch
• Parking assistance module
• Safety insert for parking aid module

3. If an obvious cause of a problem that you identified or described by the customer is found, eliminate it before proceeding with further actions (if it is possible).

4. If the cause is not visually obvious, refer to the Parking Assist Module Reinstallation Procedure.

Parking Assist Module Reinstallation Procedure

1. Turn the ignition key to position 0.

2. Detach the safety insert of the parking aid module.

3. Turn the ignition key to position II.

4. Select reverse gear, then deselect reverse gear.

5. Turn the ignition key to position 0.

6. Connect the safety plug of the parking aid module.

7. Check the correct operation of the system. If the problem persists, refer to the self-diagnosis mode.

Self-diagnosis mode

1. To enter the parking aid module self-test mode, turn the ignition key to position 0, remove the parking aid module safety plug, and make sure the gear is in neutral.

2. Make sure there are no obstacles within 2 meters of the rear of the vehicle.

3. Turn the ignition key to position II and select reverse gear.

4. The self-diagnostic mode is indicated by an audible signal from the parking aid module speaker for three seconds with a pause of one second.


5. If a fault is detected in the parking aid sensor, the parking aid module indicates this by a sequence of beeps from the parking aid speaker.

6. If a malfunction is detected in several sensors of the parking assistance system, after the first sequence, a second sequence is issued.

7. To exit the self-diagnostic mode, select the neutral position, turn the ignition key to position 0 and install the safety insert of the parking aid module.

Beep sequence

Beep sequence	Description	Actions
Three second beep, one second pause	Starting sequence for troubleshooting	-
One-time signal on and off, one second pause	Right external sensor malfunction	REFER to paragraph "Checking the elements" in the description of this procedure.
Two-time switching on and off the signal, a second pause	Right Inner Sensor Malfunction	REFER to paragraph "Checking the elements" in the description of this procedure.
Three times turning on and off the signal, a second pause	Malfunction of the left internal gauge	REFER to paragraph "Checking the elements" in the description of this procedure.
Four times turning on and off the signal, a second pause	Malfunction of the left external sensor	REFER to paragraph "Checking the elements" in the description of this procedure.
Beep for 75ms, pause for 75ms	Module failure. Low battery voltage. Short circuit in the safety insert circuit of the parking aid module.	Go to PINPOINT TEST B.
