Does the resistance smoothly increase and/or decrease when the jumpers
are connected?
F9 CHECK THE ACTUATOR MOTOR DRIVE CIRCUITS FOR AN OPEN
NOTE:
Access to the connector in the following step is difficult. Before
performing this step, visually inspect the actuator and its harness for obvious
damage. If no damage is evident, proceed with the test.
Ignition OFF.
Disconnect:
For DTC B1263
, Panel/Defrost Door Actuator C2248.
Disconnect:
For DTC B1264
, Floor Door Actuator C234.
DTC B1263
NOTE:
For
DTC B1263
only.
Measure the resistance between HVAC module C228a-24, circuit 1379 (PK/LB),
harness side and panel/defrost door actuator C2248-1, circuit 1379 (PK/LB),
harness side.
DTC B1263
NOTE:
For
DTC B1263
only.
Measure the resistance between HVAC module C228a-25, circuit 1380 (TN/YE),
harness side and panel/defrost door actuator C2248-6, circuit 1380 (TN/YE),
harness side.
DTC B1264
NOTE:
For
DTC B1264
only.
Measure the resistance between HVAC module C228a-22, circuit 1375 (PK/YE),
harness side and floor door actuator C234-1, circuit 1375 (PK/YE), harness side.
DTC B1264
Yes
INSPECT for broken door and linkage. REPAIR as necessary. If no condition is found,
GO to
F10
.
No
REPAIR the circuit(s) for an open. CLEAR the DTCs. REPEAT the self-test. TEST the
system for normal operation.
