DTC B1163: Gauge Control Module Lost Communication With Left Power Sliding Door control Unit (PSDL Frame)

NOTE: If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

Clear the DTCs with the HDS.
Turn the ignition switch to LOCK (0), and then back to ON (II).
Wait for at least 6 seconds.
Check for DTCs with the HDS.
Is DTC B1163 indicated?

YES -Go to step 5.

NO -Intermittent failure, the system is OK at this time. Check for loose or poor connections between the gauge control module and the left power sliding door control unit.
From the BODY ELECTRICAL SYSTEM SELECT menu, select B-CAN CONTROL UNITS INFORMATION, and then select CHECK CONNECTED CONTROL UNITS.
Is the left power sliding door unit detected?

YES -Go to step 10.

NO -Go to step 6.
Measure the voltage between body ground and left power sliding door control unit connector B (16P) terminals No. 1 and No. 8 individually.

Is there battery voltage?

YES -Go to step 9.

NO -Go to step 7.
Turn the ignition switch to LOCK (0).
Check the No. B16 (10 A) fuse in the under-hood fuse/relay box and the No. E13 (7.5 A) fuse in the rear fuse box.
Are the fuses OK?

YES -Repair an open or high resistance in the No. B16 (10 A) and/or No. E13 (7.5 A) fuse circuit.

NO -Replace the fuse(s). If the fuse blows again, repair a short to ground in the No. B16 (10 A) and/or No. C10 (15 A) and/or No. E13 (7.5 A) fuse circuit.
Measure the voltage between body ground and left power sliding door control unit connector B (16P) terminal No. 2.

Is there less than 0.2 V?

YES -Go to step 9.

NO -Repair an open or high resistance in the ground wire or poor ground (G602).
Turn the ignition switch to LOCK (0).
Disconnect the gauge control module 32P connector.
Disconnect left power sliding door control unit connector B (16P).
Check for continuity between left power sliding door control unit connector B (16P) terminals No. 12 and No. 14 and gauge control module 32P connector terminals No. 29 and No. 30 respectively.
