Control Assembly: Testing and Inspection

AIR CONDITIONING: AIR CONDITIONING PANEL: INSPECTION

1. INSPECT INTEGRATION CONTROL AND PANEL ASSEMBLY

(a) Check the blower switch resistance.





(1) Using an ohmmeter, measure the resistance and check the results in accordance with the values in the table below.

Standard resistance:





If the result is not as specified, replace the integration control and panel assembly.

(b) Inspect the illumination operation.





(1) Connect the positive (+) lead from the battery to terminals 1 (IG+) and 2 (ILL+) and the negative (-) lead to terminal 20 (GND), then check that the illuminations light up.

Standard:

Illuminations light up

If the result is not as specified, replace the integration control and panel assembly.

(c) Inspect the A/C indicator operation.





(1) Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminals 8 (BLW) and 20 (GND).

(2) Push the A/C button in and then check that the indicator lights up.

Standard:





HINT
Inspect the A/C indicator operation in any position except MAX COOL. The A/C indicator ON/OFF operation does not function in MAX COOL position (The A/C indicator is held in ON state).

If the result is not as specified, replace the integration control and panel assembly.

(3) Under the above condition, connect the positive (+) lead from the battery to terminal 2 (ILL+) and then check that the indicator dims.





Standard:





HINT
Inspect the A/C indicator operation in any position except MAX COOL. The A/C indicator ON/OFF operation does not function in MAX COOL position (The A/C indicator is held in ON state).

If the result is not as specified, replace the integration control and panel assembly.

(d) Inspect the REC indicator operation.





(1) Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminal 20 (GND).

NOTICE:
Inspect the MODE switch in any position except DEF.

(2) Push the REC button in and check that the indicator lights up.

Standard:





If the result is not as specified, replace the integration control and panel assembly.

(3) Under the above condition, connect the positive (+) lead from the battery to terminal 2 (ILL+) and then check that the indicator dims.

NOTICE:
Inspect the MODE switch in any position except DEF.





Standard:





If the result is not as specified, replace the integration control and panel assembly.

(e) Inspect the temperature control switch operation.





(1) Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminals 8 (BLW) and 20 (GND).

NOTICE:
Inspect the MODE switch in any position other than DEF and FOOT/DEF.

(2) Check the A/C indicator and REC indicator operations when the temperature switch is operated.

Standard:





HINT
*1: The A/C indicator remains illuminated even after the temperature switch is turned from this position to another. The REC indicator returns to the condition prior to turning the switch to MAX A/C. Press the A/C switch in and check that the indicator turns off.

If the result is not as specified, replace the integration control and panel assembly.

(f) Inspect MODE switch operation.





(1) Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminal 20 (GND).

(2) Check the REC indicator operation when the MODE switch is operated.

Standard:





If the result is not as specified, replace the integration control and panel assembly.
