On-vehicle inspection
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
(a) This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when these conditions are established.
Test conditions:
(b) Gauge readings (Reference)
(1) Normally functioning refrigeration system
Gauge reading
(2) The A/C system periodically changes between normal and improper function due to moisture in the refrigerant system.
(3) The A/C system does not function effectively due to insufficient cooling.
(4) The A/C system does not function effectively due to poor circulation of the refrigerant.
(5) The A/C system does not function intermittently because the refrigerant does not circulate.
(6) The A/C system does not function effectively due to overcharged refrigerant or insufficient cooling of the condenser.
(7) The A/C system does not function due to air in the refrigeration system.
CAUTION: The low-pressure piping may be very hot and cause serious burns. |
(8) The A/C system does not function effectively due to an expansion valve malfunction.
(9) The A/C system does not function due to a defective compressor.

Basic inspection
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly a ...
MIL Circuit
DESCRIPTION
The MIL (Malfunction Indicator Lamp) is used to indicate vehicle malfunctions
detected by the ECM.
When the ignition switch is turned to the ON position, power is supplied to the
MIL circuit, and the ECM
provides the circuit ground which illuminates the MIL.
The MIL operation ...
