Description & Inspection

DESCRIPTION
The purpose of the operational check is to check if the individual system operates properly.

Conditions : After READY

INSPECTION PROCEDURE

Memory Function
1. Turn temperature control dial (driver side) clockwise until 32 °C (90 °F) is displayed.
2. Press OFF switch.
3. Turn ignition switch OFF.
4. Turn ignition switch ON (READY).
5. Press AUTO switch.
6. Confirm that the set temperature remains at previous temperature.
7. Press OFF switch.

If NG, go to trouble diagnosis procedure for HAC-155, "Inspection procedure". Memory Function Does Not Operate
If OK, continue the check.

Blower
1. Turn fan control dial clockwise. Blower should operate on low speed.
2. Turn fan control dial clockwise again, and continue checking blower speed and fan symbol until all speeds are checked.
3. Leave blower on max. speed.

If NG, go to trouble diagnosis procedure for HAC-81, "Diagnosis Procedure". Blower Motor
If OK, continue the check.

Discharge Air
1. Press MODE switch and DEF switch.
2. Each position indicator should illuminate.
3. Confirm that discharge air comes out according to the air distribution table. Refer to "System Description".






If NG, go to trouble diagnosis procedure for HAC-53, "Diagnosis Procedure". B2636
If OK, continue the check.

NOTE: Confirm that the intake door position is at FRE when the D/F or DEF is selected.

Intake Air

2. Check for cold air at discharge air outlets.

If NG, go to trouble diagnosis procedure for HAC-151, "Inspection procedure". Insufficient Cooling
If OK, continue the check.

Temperature Increase
1. Turn temperature control dial (driver side) clockwise until 32 °C (90 °F) is displayed.

If NG, go to trouble diagnosis procedure for HAC-86, "Diagnosis Procedure" Power Supply and Ground Circuit For Auto Amp., then if necessary, trouble diagnosis procedure for HAC-90, "Diagnosis Procedure". If all operational checks are OK (symptom cannot be duplicated), go to Incident Simulation Tests in GI-38, "Work Flow" and perform tests as outlined to simulate driving conditions environment. Service Information For Electrical Incident If symptom appears, refer to HAC-150, "Diagnosis Chart By Symptom" and perform applicable trouble diagnosis procedures. Symptom Chart

AUXILIARY MECHANISM

Temperature Setting Trimmer
The trimmer compensates for differences in range of ±3 °C (±6 °F) between temperature setting and temperature felt by customer using CONSULT-III.

Operating procedures for this trimmer are as follows:
1. Turn ignition switch ON (READY).
2. Perform "TEMP SET CORRECT" in "WORK SUPPORT" with CONSULT-III.
3. Temperature will change at a rate of 0.5 °C (1.0 °F).

NOTE: When low voltage battery cable is disconnected or battery voltage is below 10 V, trimmer operation is canceled. Temperature set becomes that of initial condition, i.e. 0.0 °C (0.0 °F).

Foot Position Setting Trimmer
Wind distribution ratio in FOOT mode can be set.

Operating procedures for this trimmer are as follows:
1. Turn ignition switch ON (READY).
2. Perform "BLOWER FAN SET" in "WORK SUPPORT" with CONSULT-III.
3. Foot mode is selected by setting the following.
*: Initial setting






NOTE: When low voltage battery cable is disconnected or battery voltage is below 10 V, trimmer operation is canceled. Wind distribution ratio set becomes that of initial condition.

REC Memory Function
When ignition switch is turned from OFF to ON, inlet port can be set to AUTO or manual.

Operating procedures for this trimmer are as follows:
1. Turn ignition switch ON (READY).
2. Perform "REC MEMORY SET" in "WORK SUPPORT" with CONSULT-III.
3. REC memory function is selected by setting the following.






NOTE: When low voltage battery cable is disconnected or battery voltage is below 10 V, memory function is canceled. Memory function set becomes that of initial condition.

FRE Memory Function
When ignition switch is turned from OFF to ON, inlet port can be set to AUTO or manual.

Operating procedures for this trimmer are as follows:
1. Turn ignition switch ON (READY).
2. Perform "FRE MEMORY SET" in "WORK SUPPORT" with CONSULT-III.
3. FRE memory function is selected by setting the following.






NOTE: When low voltage battery cable is disconnected or battery voltage is below 10 V, memory function is canceled. Memory function set becomes that of initial condition.
