ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
(a) This is a method to specify trouble areas by using a manifold gauge set. Read the manifold gauge pressure when the following conditions are established.
Test conditions:
Gauge readings (Reference)
(1) When the refrigerant volume is proper: Gauge reading: Low pressure side: 150 to 250 kPa (1.5 to 2.5 kgf/cm2, 22 to 36 psi) High pressure side: 1370 to 1570 kPa (14.0 to 16.0 kgf/cm2, 199 to 228 psi) |
|
(2) When there is moisture in the refrigeration system:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
During operation, pressure on low pressure side cycles between normal and vacuum |
Moisture in refrigeration system freezes at expansion valve orifice, causing temporary stop of cycle. However, when melted, normal state restored |
|
|
(3) When cooling is insufficient:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
Gas leakage from refrigeration system |
|
|
(4) When the circulation of the refrigerant is poor:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Refrigerant flow obstructed by dirt in condenser |
Condenser clogged |
Replace condenser |
(5) When the refrigerant does not circulate:
Symptoms |
Probable Causes |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
|
Refrigerant does not circulate |
|
(6) When the refrigerant is overcharged or cooling of condenser is insufficient:
Symptoms |
Probable Causes |
Diagnosis |
Corrective Actions |
---|---|---|---|
Pressure extremely high on both low and high pressure sides |
|
|
|
(7) When there is air in the refrigeration system:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Actions |
---|---|---|---|
|
Air in refrigeration system |
|
|
(8) When the expansion valve malfunctions:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Trouble in expansion valve |
|
Replace expansion valve |
(9) When the compressor is defective:
Symptoms |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Internal leakage in compressor |
|
Repair or replace compressor |

Short in Curtain Shield Squib LH Circuit (B1835/58-B1838/58)
DESCRIPTION
The driver side curtain shield squib circuit consists of the airbag sensor assembly
and the curtain shield airbag assembly LH.
The circuit signals the SRS to deploy when airbag deployment conditions are met.
These DTCs are set when a malfunction is detected in the driver side curtai ...
Destination Information Undefined (C1AB8)
DESCRIPTION
This DTC is stored when correct destination information is not sent from the
main body ECU (multiplex network body ECU) and destination information cannot be
confirmed after a blind spot monitor has been replaced.
