1) Remove air flow control actuator from HVAC unit referring to “Air Flow C ontrol Actuator Removal and
Installation”.
2) Connect actuator connector to the actuator.
3) Set air flow selector of HVAC control module to DEF position with ignition switch ON, and make sure if the
position of actuator lever is DEF position (8).
4) Turn ignition switch OFF, and then disconnect connector from air flow control actuator.
5) Measure resistance between terminal “3” and “5”

DTC Will Set when
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connector
terminal contact is above a spec ified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
Step 2: Check driver air bag (inflator) module initiator circuit. (in instrument panel and floor harness)
Step 3: Check driver air bag (inflator) module initiator circuit. (in floor harness)
Step 4: Check whether malfunction is in contact coil or driver air bag (inflator) module.
DTC Troubleshooting
Step Action Yes No 1 1) With ignition switch OFF, disconnect contact coil connector located under of the steering column.
2) Check proper connection to contact coil at terminal in “G26” connector.
3) If OK, then connect special tools (B) and (C) to “G26” connector disconnected in Step 1).
Special tool
(B): 09932-75010
(C): 09932–78340
4) Check SDM DTC.
With ignition switch ON , is DTC B1031 indicated? Go to Step 2. Go to Step 4.
