DTC B1208 INTAKE POTENTIOMETER OPEN
COMPONENT LOCATION
EF749215
Intake Door Actuator
SCMHA6701L
GENERAL DESCRIPTION
EA50D8D5
Intake door located at heater unit controls the inlet of car. When driver operates the intake switch, A/C controller recir-
culationeives mode signal from intake switch and operates intake door actuator to turn intake door to intended position.
(with fresh mode signal, intake door is closed and with fresh mode signal, intake door is opened).
DTC DESCRIPTION
E6782025
The A/C controller sets DTC B1208 if there is an open circuit or poor connection in the intake potentiometer.

4.
Are the DTC B1208 present and is parameter of "Intake Potentiometer" fixed?
※
Parameter of "Intake Potentiometer" will be fixed at 100%(or any value above 90%), or 0% (or any value below
10%), if there is any fault in Intake potentiometer.
YES
Go to "Inspection" procedure.
NO
Fault is intermittent caused by poor contact in the sensor’s and/or A/C controller’s connector or was repaired and
A/C controller memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending,
corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of
Vehicle Repair" procedure.
TERMINAL AND CONNECTOR INSPECTION
E0353933
1.
Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.
3.
Has a problem been found?
YES
Repair as necessary and go to "Verification of Vehicle Repair" procedure.

1.
Check for open in harness.
1) Ignition "OFF"
2) Disconnect Intake potentiometer.
3) Measure resistance between terminal "6" of Intake Potentiometer and terminal "24" of A/C control unit.

NO
Check for open in signal harness. Repair as necessary and go to "Verification of Vehicle Repair" procedure.
2.
Check for short to ground in harness.
1) Ignition "OFF"
2) Disconnect Intake potentiometer.
3) Measure resistance between terminal "6" of Intake Potentiometer and chassis ground.
Specification : Approx. ∞ Ω
