Diagnostic Procedure for Actuators
HVAC SYSTEM (AUTO A/C) (DIAGNOSTICS)
Step
Check
Yes
No
1
CHECK POWER SUPPLY FOR MODE DOOR
ACTUATOR POSITION SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the mode door actuator connec-
tor.
3) Turn the ignition switch and AUTO switch to
ON.
4) Measure the voltage between auto A/C con-
trol module connector terminals.
Connector & terminal
(B282) No. 8 (+) — (B282) No. 15 (–):
Is the voltage approx. 5 V?
Go to step
2
.
Replace the auto
A/C control mod-
ule. <Ref. to AC-
33, REMOVAL,
Control Unit (Auto
A/C Model).>
2
CHECK POWER SUPPLY FOR MODE DOOR
ACTUATOR.
Measure the voltage between auto A/C control
module connector and chassis ground after
turning the air flow control switch to FACE posi-
tion.
Connector & terminal
(B283) No. 7 (+) — Chassis ground (–):
Is the voltage 8 V (at normal
temperature)?
Go to step
3
.
Replace the auto
A/C control mod-
ule. <Ref. to AC-
33, REMOVAL,
Control Unit (Auto
A/C Model).>
3
CHECK POWER SUPPLY FOR MODE DOOR
ACTUATOR.
Measure the voltage between auto A/C control
module connector and chassis ground after
turning the air flow control switch to DEF posi-
tion.
Connector & terminal
(B283) No. 20 (+) — Chassis ground (–):
Is the voltage 8 V (at normal
temperature)?
Go to step
4
.
Replace the auto
A/C control mod-
ule.
4
CHECK HARNESS BETWEEN AUTO A/C
CONTROL MODULE AND MODE DOOR AC-
TUATOR.
1) Turn the A/C and ignition switch to OFF.
2) Disconnect the auto A/C control module
connector.
3) Measure the resistance between auto A/C
control module and mode door actuator con-
nector.
Connector & terminal
(B77) No. 1 — (B282) No. 15:
(B77) No. 3 — (B282) No. 8:
(B77) No. 5 — (B282) No. 3:
(B77) No. 6 — (B283) No. 20:
(B77) No. 7 — (B283) No. 7:
Is the resistance less than 1
Ω
? Go to step
5
.
Repair the harness
between auto A/C
control module and
mode door actua-
tor.
5
CHECK MODE DOOR ACTUATOR POSI-
TION SWITCH SIGNAL.
1) Connect the connector of auto A/C control
module and mode door actuator.
2) Turn the ignition switch and AUTO switch to
ON.
3) Check the voltage between auto A/C control
module connector terminals while changing the
mode between DEF and FACE.
Connector & terminal
(B282) No. 3 (+) — (B282) No. 15 (–):
Does the voltage change
between 1 V (DEF) and 4 V
(FACE)?
Go to step
6
.
Replace the mode
door actuator.

MODE DOOR
ACTUATOR,
REMOVAL, Actua-
tor.>
6
CHECK POOR CONTACT.
Check poor contact of auto A/C control module
and connector.
Is there poor contact in connec-
tor?
Repair the connec-
tor.
Replace the auto
A/C control mod-
ule. <Ref. to AC-
33, REMOVAL,
Control Unit (Auto
A/C Model).>
