DTC U1288  : Gauge Control Module Lost Communication With PARKSR

DTC (Gauge Control Module)

1. Problem verification

   - 1. Clear the DTCs with the HDS.

   - 2. Turn the vehicle to the OFF (LOCK) mode and then the ON mode.

   - 3. Wait for at least 6 seconds.

   - 4. Check for DTCs with the HDS.

   DTC Description	DTC
   U1288 Gauge Control Module Lost Communication With PARKSR

   Is DTC U01288 indicated?

   YES 

   Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for loose or poor connections.

2. Determine possible failure area (Parking and back-up sensor control unit power and ground, B-CAN line)

   - 1. Select B-CAN CONTROL UNITS INFORMATION from the BODY ELECTRICAL SYSTEM SELECT menu, and then select CHECK CONNECTED CONTROL UNITS.

   - 2. Check the DETECT/NOT AVAILABLE information of the PARKING SENSOR MODULE

   Is DETECT indicated?

   YES 

   Go to step 7.

   NO 

   Go to step 3.

3. Fuse check

   - 1. Check the following fuse.

   Fuse	No. D11 (7.5 A)
   Location	Driver's under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 4.

   NO 

   Replace the fuse. If the fuse blows again, repair a short to ground in the No. D11 (7.5 A) fuse circuit.

4. Open wire check (IG1 METER line)

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Disconnect the following connector.

   Parking and back-up sensor control unit 24P connector

   - 3. Turn the vehicle to the ON mode.

   - 4. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode Parking and back-up sensor control unit 24P connector: disconnected
   Test point 1	Parking and back-up sensor control unit 24P connector No. 1 - Refer to: Parking and Back-Up Sensor Control Unit Input Test (2014 2015 2016)
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The IG1 METER wire is OK. Go to step 5.

   NO 

   Repair an open or high resistance in the wire.

5. Open wire check (GND line)

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode Parking and back-up sensor control unit 24P connector: disconnected
   Test point 1	Parking and back-up sensor control unit 24P connector No. 12 - Refer to: Parking and Back-Up Sensor Control Unit Input Test (2014 2015 2016)
   Test point 2	Body ground

   Is there continuity?

   YES 

   The GND wire is OK. Go to step 6.

   NO 

   Repair an open or high resistance in the ground wire or poor ground (G507).

6. Open wire check (B-CAN lines)

   - 1. Disconnect the following connector.

   Gauge control module 32P connector

   - 2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode Parking and back-up sensor control unit 24P connector: disconnected Gauge control module 32P connector: disconnected
   Test point 1	Parking and back-up sensor control unit 24P connector No. 22 - Refer to: Parking and Back-Up Sensor Control Unit Input Test (2014 2015 2016)
   Test point 2	Gauge control module 32P connector No. 25 - Refer to: Gauge Control Module Input Test (2016), .

   Is there continuity?

   YES 

   An open or poor connection in the B-CAN_L wire between the parking and back-up sensor control unit and the gauge control module.

   NO 

   An open or poor connection in the B-CAN_H wire between the parking and back-up sensor control unit and the gauge control module.

7. Open wire check (B-CAN lines)

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Disconnect the following connectors.

   Parking and back-up sensor control unit 24P connector

   Gauge control module 32P connector

   - 3. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode Parking and back-up sensor control unit 24P connector: disconnected Gauge control module 32P connector: disconnected
   Test point 1	Parking and back-up sensor control unit 24P connector No. 22 - Refer to: Parking and Back-Up Sensor Control Unit Input Test (2014 2015 2016)
   Test point 2	Gauge control module 32P connector No. 25 - Refer to: Gauge Control Module Input Test (2016),

   Is there continuity?

   YES 

   An open or poor connection in the B-CAN_L wire between the parking and back-up sensor control unit and the gauge control module.

   NO 

   An open or poor connection in the B-CAN_H wire between the parking and back-up sensor control unit and the gauge control module.
