INSPECTION PROCEDURE
HINT:
1 CHECK FRONT PASSENGER AIRBAG ASSEMBLY (FRONT PASSENGER SIDE SQUIB)

CAUTION: Never connect a tester to the front passenger airbag assembly (front passenger side squib) for measurement, as this may lead to a serious injury due to airbag deployment.
NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.
Insert the SST straight into the terminals of the connector.

Air Mix Damper Control Servo Motor Circuit (Passenger Side)
DESCRIPTION
The air mix control servo motor (air mix damper servo sub-assembly) is
controlled by the A/C amplifier.
The air mix control servo motor moves the air mix damper by rotating (normal,
reverse) with electrical
power from the A/C amplifier.
This adjusts the mix ratio of the air t ...
