B127C

B127C-PTS SENSOR 11 CIRCUIT LOW







NOTE: The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since Chrysler Group vehicles use only four rear sensors, sensor number 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.

- When Monitored:

While the vehicle is in reverse for speeds less than 16km/h (10 mph).

- Set Condition:

This DTC will set if the sensor is disconnected, faulty, or the Park Assist Sensor Signal circuit is shorted to ground.







Diagnostic Test

1. CHECK FOR ACTIVE DTC

NOTE: Verify that the Park Assist Sensor is properly connected. Inspect the sensor connector for broken, bent, pushed out, spread, corroded, or contaminated terminals.

Turn the ignition on.

With the scan tool, read Park Assist Module DTCs.

Is this DTC active?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

2. CHECK PARK ASSIST SENSOR NO. 11

Turn the ignition off.

Disconnect Park Assist Sensor No. 11.

Connect a jumper wire between the (X700) Park Assist Sensor Supply and the (D710) Park Assist Sensor No. 11 Signal circuits.

Turn the ignition on.

Shift the transmission into reverse.

With the scan tool, read Park Assist Module DTCs.

Is this DTC active?

Yes

- Go To 4

No

- Replace Park Assist Sensor No. 11.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

3. CHECK THE (D710) PARK ASSIST SENSOR NO. 11 SIGNAL CIRCUIT FOR AN OPEN







Measure the resistance of the (D710) Park Assist Sensor No. 11 Signal circuit between the Park Assist Module C2 harness connector and the Park Assist Sensor No. 11 harness connector.

Is the resistance below 5.0 ohms?

No

- Go To 4

Yes

- Repair the (D710) Park Assist Sensor No. 11 Signal circuit for an open.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

4. CHECK THE (D710) PARK ASSIST SENSOR NO. 11 SIGNAL CIRCUIT FOR A SHORT TO (X750) PARK ASSIST SENSOR GROUND CIRCUIT






Turn the ignition off.

Disconnect the Park Assist Module C2 harness connector.

Measure the resistance between the (D710) Park Assist Sensor No. 11 Signal circuit and the (X750) Park Assist Sensor Ground circuit.

Is the resistance below 10K ohms?

Yes

- Repair the (D710) Park Assist Sensor No. 11 Signal circuit for a short to the (X750) Park Assist Sensor Ground circuit.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

No

- Go To 5

5. CHECK THE (D710) PARK ASSIST SENSOR NO. 11 SIGNAL CIRCUIT FOR A SHORT TO (X772) PARK ASSIST DISPLAY GROUND CIRCUIT






Measure the resistance between the (D710) Park Assist Sensor No. 11 Signal circuit and the (X772) Park Assist Display Ground circuit.

Is the resistance below 10K ohms?

Yes

- Repair the (D710) Park Assist Sensor No. 11 Signal circuit for a short to the (X772) Park Assist Display Ground circuit.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

No

- Go To 6

6. CHECK THE (D710) PARK ASSIST SENSOR NO. 11 SIGNAL CIRCUIT FOR A SHORT TO (Z177) PARK ASSIST MODULE GROUND CIRCUIT






Measure the resistance between the (D710) Park Assist Sensor No. 11 Signal circuit and the (Z177) Park Assist Module Ground circuit.

Is the resistance below 10K ohms?

Yes

- Repair the (D710) Park Assist Sensor No. 11 Signal circuit for a short to ground to the (Z177) Park Assist Module Ground circuit.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

No

- Go to 7

7. CHECK THE (D710) PARK ASSIST SENSOR NO. 11 SIGNAL CIRCUIT FOR A SHORT TO GROUND






Using a 12-volt test light connected to 12 Volts, probe the (D710) Park Assist Sensor No. 11 Signal circuit and ground.

Does the test light illuminate?

Yes

- Repair the (D710) Park Assist Sensor No. 11 Signal circuit for a short to ground.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test

No

- Replace the Park Assist Module.
- Perform BODY VERIFICATION TEST, refer to Body Verification Test
