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.
8. Exchange the suspect sensor with another sensor
within the bumper that is not reporting a fault. Reconnect

all sensors and reconnect the bumper main harness
connector. Repeat Step 1. Confirm if the original fault
code now appears at the new position of the suspect
sensor, if so, proceed to step 9. If not, carry out the
appropriate "Open Circuit and Short Circuit" checks
between the original suspect sensor harness connector
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.
11. Repeat Step 1. If fault code is still present ONLY
REPLACE THE FAULTY SENSOR. Repeat step 1 to
determine that all faults are now cleared.
