B2630, B2631 SUNLOAD SENSOR
DTC CONFIRMATION PROCEDURE
1.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT-III
1. Using CONSULT-III, perform “SELF-DIAGNOSIS RESULTS” of HVAC.
2. Check if any DTC is displayed in the self-diagnosis results.
NOTE:
 If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to HAC-
42, "DTC Logic" or HAC-43, "DTC Logic".
 Sunload sensor may register a malfunction when indoors, at dusk, or at other times when light is insufficient.
When performing the diagnosis indoors, light the sunload sensor with a lamp (60 W or more).
Is DTC
“B2630” or “B2631” displayed?
YES >> Perform trouble diagnosis for the sunload sensor. Refer to HAC-54, "Diagnosis Procedure".
NO >> INSPECTION END

B2632, B2633 AIR MIX DOOR MOTOR (DRIVER SIDE)
DescriptionINFOID:0000000003846347
COMPONENT DESCRIPTION
Air Mix Door Motor (Driver Side)
 The air mix door motor (driver side) (1) are attached to the heater
& cooling unit assembly.
 It rotates so that the air mix door is opened or closed to a position
set by the A/C auto amp.
 Motor rotation is then conveyed through a shaft and the air mix
door position feedback is then sent to the A/C auto amp. by PBR
built-in air mix door motor.
