5. Turn ignition off. Check continuity between ground and terminal "A" (Light Blue/Black
wire) of sunload temperature sensor harness connector. If continuity exists, repair short to
ground in Dark Green wire between inside sunload temperature sensor and terminal D2 of
HVAC control head harness connector. After repair, go to step 12 . If continuity does not
exist, go to step 10 .
6. Measure voltage between ground and terminal "A" (Light Blue/Black wire) of sunload
temperature sensor. If voltage exists, repair short to voltage in Light Blue/Black wire
between sunload temperature sensor and terminal C2 of HVAC control head harness
connector. After repair, go to step 12 . If voltage does not exist, check continuity in Light
Blue/Black wire between terminal "A" of sunload temperature sensor and terminal C2 of
HVAC control head harness connector. If continuity exists, go to next step. If continuity
does not exist, repair open or high resistance in Light Blue/Black wire and go to step 12 .
7. Check continuity in Gray/Black wire between terminal "B" of sunload sensor and terminal
D1 of HVAC control module. If continuity exists, go to step 10 . If continuity does not
exist, repair open in Gray/Black wire and go to step, 12 .
8. Check for loose wires and or poor connections at sunload temperature sensor. Repair any
problems found and go to step 12 . If wiring and connectors are okay, go to step 10 .
9. Check for loose wires and or poor connections at HVAC control head. Repair any problems
found and go to step 12 . If wiring and connections are okay, go to step 11 .
10. Replace sunload temperature sensor. See SUNLOAD TEMPERATURE SENSOR under
REMOVAL & INSTALLATION. After repair, go to step 12 .
11. Replace HVAC control head. See HVAC CONTROL HEAD under REMOVAL &
INSTALLATION and go to next step.
12. Use scan tool to clear DTCs. See CLEARING TROUBLE CODES . Operate vehicle and
verify that DTCs do not reset. If DTCs reset, go to step 3 . If DTCs do not reset, system is
okay.
DTC B0361: LEFT ACTUATOR FEEDBACK SHORT TO GROUND
Diagnostic Aids
If DTC is intermittent or has a history, perform tests while wiggling wiring and connectors. This
can often cause the malfunction to appear. Inspect sensor connector and harness for damage,
corrosion or water intrusion. Check for adequate terminal tension, harness routing, damaged wire
insulation, and broken wires.
Connect a scan tool to Diagnostic Link Connector (DLC) and turn ignition on. Select OUTPUT
CONTROL screen in HVAC SPECIAL FUNCTIONS. Use MISCELLANEOUS TEST screen to
manually drive LH ELECTRIC ACTUATOR with scan tool from fully open to fully closed. Use
