Is the resistance between 250 and 5,500 ohms?
F5 CHECK CIRCUITS 438 (RD/WH), 1123 (YE/WH) AND 1130 (PK/LG) FOR A
SHORT TO VOLTAGE
Ignition ON.
Measure the voltage between ground and:
HVAC module C228a-20, circuit 438 (RD/WH), harness side.
For DTC B1263, HVAC module C228b-15, circuit 1123 (YE/WH), harness
side.
For DTC B1264, HVAC module C228b-14, circuit 1130 (PK/LG), harness
side.
Is any voltage present?
F6 CHECK CIRCUITS 436 (RD/LG), 1123 (YE/WH) AND 1130 (PK/LG) FOR A
SHORT TO GROUND
Ignition OFF.
Measure the resistance between ground and:
HVAC module C228b-8, circuit 436 (RD/LG), harness side.
For DTC B1263, HVAC module C228b-15, circuit 1123 (YE/WH), harness
side.
For DTC B1264, HVAC module C228b-14, circuit 1130 (PK/LG), harness
side.
Is the resistance greater than 10,000 ohms?
F7 CHECK THE DOOR ACTUATOR OPERATION
NOTE: If a jumper fuse opens while carrying out this test step, repair the circuit
(s) for a short.
With the fused jumper connections made as directed below, measure the
resistance between HVAC module C228a-20, circuit 438 (RD/WH), harness side
and HVAC module C228b-15, circuit 1123 (YE/WH), harness side.
Connect a fused jumper wire between:
HVAC module C228a-25, circuit 1380 (TN/YE), harness side and HVAC
module C228b-11, circuit 1566 (RD/YE), harness side.
HVAC module C228a-24, circuit 1379 (PK/LB), harness side and HVAC
module C228a-2, circuit 57 (BK), harness side.

Yes
REPAIR circuit 438 (RD/WH), 1123 (YE/WH) or 1130 (PK/LG) for a short to voltage.
CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
No
GO to F6.
Yes
If diagnosing DTC B1263, GO to F7.
If diagnosing DTC B1264, GO to F8.
No
REPAIR circuits 436 (RD/LG), 1123 (YE/WH) or 1130 (PK/LG) for a short to ground.
CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
Yes
INSPECT for broken door and linkage. REPAIR as necessary. If no condition is found,
GO to F11.
No
GO to F9.
