VehiCROSS 4WD V6-3.5L (1999)
-
The engine speed is greater than 4500 RPM for 5 seconds or 5400 RPM.
-
The engine coolant temperature (ECT) is greater than 125° C (257° F).
-
The intake air temperature (IAT) is less than 5° C (41° F). The power steering pressure switch signals a high pressure condition.
Diagnostic Aids
To diagnose an intermittent fault, check for following conditions:
-
Poor connection at the PCM-Inspect connections for backed-out terminals, improper mating, broken locks, improperly formed or damaged
terminals, and poor terminal-to-wire connection.
-
Damaged harness-Inspect the wiring harness for damage. If the harness appears to Ok, observe the A/C clutch while moving connectors and wiring
harnesses related to the A/C. A sudden clutch malfunction will indicate the source of the intermittent fault.
A/C Clutch Diagnosis
This chart should be used for diagnosing the electrical portion of the A/C compressor clutch circuit. A Tech 2 will be used in diagnosing the system.
The Tech 2 has the ability to read the A/C request input to the PCM. The Tech 2 can display when the PCM has commanded the A/C clutch "ON."
The Tech 2 should have the ability to override the A/C request signal and energize the A/C compressor relay.
