B1235 PTS SENSOR 9 CIRCUIT PERFORMANCE





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

During Reverse and during self test in Forward between 18 km/h (11 mph) and 40 km/h (25 mph).

- Set Condition:

If the system detects data corruption in the transmission in the internal communication line between the module and sensors, this code will set.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.

Apply the vehicle park brake.

Shift the transmission into reverse.

With the scan tool, record and erase Park Assist Module DTCs.

Wait 30 seconds.

With the scan tool, read Park Assist Module DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. CHECK PARK ASSIST SENSOR NO. 9 FOR INTERNAL SHORT





Disconnect Park Assist Sensor No. 9.

With the scan tool, read Park Assist Module DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

- Replace Park Assist Sensor No. 9.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

3. CHECK THE (D703) PARK ASSIST SENSOR NO. 9 SIGNAL CIRCUIT FOR A SHORT TO GROUND





Turn the ignition off.

Disconnect the Park Assist module harness connectors C1 and C2.

Using a 12-volt test light connected to 12-volts check the (D703) Park Assist Sensor No. 9 Signal circuit at the Park Assist module C2 harness connector.

Does the test light illuminate brightly?

Yes

- Repair the (D703) Park Assist Sensor No. 9 Signal circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 4

4. CHECK THE (D703) PARK ASSIST SENSOR NO. 9 SIGNAL CIRCUIT FOR A SHORT TO BATTERY





Turn the ignition on.

Using a 12-volt test light connected to ground check the (D703) Park Assist Sensor No. 9 Signal circuit at the Park Assist module C2 harness connector for a short to battery.

Does the test light illuminate brightly?

Yes

- Repair the (D703) Park Assist Sensor No. 9 Signal circuit for a short to battery.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 5

5. CHECK THE (D703) PARK ASSIST SENSOR NO. 9 SIGNAL CIRCUIT FOR AN OPEN





Measure the resistance of the (D703) Park Assist Sensor No. 9 Signal circuit between the Park Assist Module C2 harness connector and the Park Assist Sensor No. 9 harness connector.

Is the resistance below 5.0 ohms?

No

- Repair the (D703) Park Assist Sensor No. 9 Signal circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Yes

- Replace the Park Assist Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
