CONSULT INSPECTION PROCEDURE





1. Turn off ignition switch.





2. Connect "CONSULT" to data link connector. (Data link connector is located in left dash side panel.)





3. Turn on ignition switch.
4. Touch "START".





5. Touch "AUTO A/C".





6. Perform each diagnostic mode according to the inspection sheet.

WORK SUPPORT

SEGMENT CHECK: Checks L.E.D.s and Segments





Touch "SEGMENT CHECK".
When switch's L.E.D. and segments are in good order in WORK SUPPORT - Segment check mode, the corresponding L.E.D. and fluorescent display tube will illuminate.





If L.E.D.s or segments malfunction, L.E.D. will not come on or display will show incomplete segment.

MODE DOOR CHECK: Checks mode door position





Touch "MODE DOOR CHECK" and then touch "START". When all doors are functioning, display will show "NO FAILURE".





When abnormalities are detected, display shows a malfunction position.
If two or more mode doors are out of order, corresponding mode doors respectively blink two times.
If any mode door motor harness connector is disconnected, display will show all mode door positions.
If any mode door motor position switch is malfunctioning, mode door motor will also malfunction.

INTAKE DOOR CHECK: Checks Intake door position.





Touch "INTAKE DOOR CHECK", and then touch "START" When all doors are in good order, display will show "NO FAILURE".





When abnormalities are detected, display shows a malfunction position.
If two or more intake doors are out of order, corresponding intake doors respectively blink two times.
If intake door motor harness connector is disconnected, display will show all positions except "FRE".
If any intake door motor position switch is malfunctioning, intake door motor will also malfunction.

TEMP SETTING TRIMMER: Temperature selling trimmer.
This trimmer compensates for differences between temperature setting (Displayed digitally) and temperature felt by the driver in a range of ±3°C (±6°F).
Operation procedures for this trimmer are as follows:





Touch "TEMP SETTING TRIMMER", and then touch "START".
Next, touch either the UP or DOWN switch as desired.
Temperature will change at a rate of 0.5°C (1°F) each time a switch is touch.

When battery cable is disconnected, trimmer operation is canceled and temperature set returns to the initial condition i.e. 0°C 0°F).





MAX. OUTLET FLOW ADJUSTMENT: Adjustment of highest blower fan speed.
For passenger's comfort, maximum air flow of automatic control (blower motor voltage) can be set at three different levels. Operating procedure for this adjustment are as follows:
Touch "MAX OUTLET FLOW ADJUSTMENT", and touch "START". Then, touch either UP or DOWN switch as desired.





FAN SPEED CONTROL ADJUSTMENT: Adjustment of highest blower fan speed changing point.
For passenger's comfort, blower high relay operating time period during cool down (voltage changes from 12V to 1O.5V) can be set at three different levels.
Operating procedure for this adjustment are as follows:
Touch "FAN SPEED CONTROL ADJUSTMENT", and touch "START". Then, touch either UP or DOWN switch as desired.





MODE DOOR CONTROL ADJUSTMENT: Adjusting outlet door changing point.
For passenger's comfort, time setting when changing from B/L to F/D mode can be set at three different levels. (Operating procedure for this adjustment are as follows:) Touch "MODE DOOR CONTROL ADJUSTMENT", and then touch "START". Then, touch UP switch as desired.





SELF-DIAGNOSTIC RESULTS
Check each sensor circuit for open or short circuit.





Touch "SELF-DIAGNOSTIC RESULTS", and then touch "START". When all sensors are in good order, display will show "NO SELF DIAGNOSTIC FAILURE INDICATED".

CAUTION:
- Before conducting SELF-DIAGNOSTIC RESULTS mode, warm up engine. When engine coolant temperature is low, display can sometimes show "WATER TEMPERATURE SENSOR [OPEN] (.a)" even though the sensor is functioning properly.
- Conduct SELF-DIAGNOSTIC RESULTS mode under direct sunshine if possible. When conducting indoors, direct electric light (mm. 60W) on the sunload sensor. Otherwise, display will show "SUNLOAD SENSOR [OPEN] (.a)" even when the sensor Is functioning properly.





If a sensor is malfunctioning, the corresponding sensor on display.
If circuit is opened, [OPEN] (.a)
If circuit is shorted, [SHORT] (.b)





DATA MONITOR

ACTIVE TEST
Checks operation of each actuator.
Mode in which CONSULT drives some actuators apart from the auto amp. and also shifts some parameters in a specified range.
Checks must be made visually, by listening for noise, or by touching air outlets with hand, etc for improper operation. Touch "ACTIVE TEST".
Touch "COMPLEX PATTERNS".
Touch "START". Display shows STEP 1 in "ACTIVE TEST" mode.
