Symptom 206000 Warning Indicators

Issue

Park Distance Control (PDC) sensors are being returned

with no faults found or signs of water ingress/corrosion.

Cause

Possible manufacturing issue with sensor connectors not

latched correctly

Action

When either no/intermittent operation has been reported

the following action should be taken if SDD reports a

permanent or intermittent sensor failure with either one (or

a combination) of the following failure descriptions

General Electrical Failure (0x01)

Circuit Short to Battery (0x12)

Circuit Short to Ground or Open (0x14)

Component Internal Failure (0x96)

1. Using SDD identify the position of the suspect sensor

within bumper. Confirm that the failure type is either 0x01,

0x12, 0x14 or 0x96.

2. Visually locate the position of the suspect sensor.

Inspect and provide details in the claim if the sensor has

any sign of damage.

3. Remove the bumper. Disconnect the wiring at the main

harness connector. Inspect the main harness connector &

Content terminals for signs of damage, backed out pins,

corrosion/water ingress, or damage to the seals. Provide

details in the claim.

4. Attempt to remove the harness connector from the

suspect sensor without using the connector latch i.e.

lightly pull back on ALL wires together ensuring the

harness is held close to the back of the connector. DO

NOT APPLY EXCESSIVE FORCE. If the connector can

be removed without using the latch, provide details in the

claim. If the connector is fully latched disconnect from the

sensor.

5. Inspect the suspect sensor harness connector for any

sign of water ingress/corrosion.

6. Inspect and provide details in claim if the suspect

sensor harness connector shows any sign that the

terminals have “backed-out” of the connector or for any

damage to the terminal seals. Replace/repair the harness

as required and proceed.

7. Remove the suspect sensor from the bumper. Inspect

the sensor connector for signs of water ingress/corrosion.

Provide details in the claim if corrosion/water ingress is

present.

and the PDC module

9. Refit the sensors to their original position in the

bumper.

10. Reconnect the sensor to the bumper harness

connector. Reconnect main harness connector and refit

the bumper.
