PINPOINT TEST D: DTC B2518 COMPRESSOR OVERTEMPERATURE FAULT
TEST STEP
ACTION TO TAKE
D1 CHECK FOR A/C TEMPERATURE SENSOR OUT OF RANGE
FAULT
•
Check the interface adapter assembly (IAA) module for continuous Yes = GO to
diagnostic trouble codes (DTCs).
•
Does DTC B2606 A/C Temperature Sensor Out of Range occur
No =
GO to D2.
along with DTC B2518 Compressor Overtemperature Fault?
D2 CHECK COMPRESSOR TEMPERATURE
•
With key ON, monitor IAA module PID AC CTMP.
Yes =
GO to D3.
•
Is the temperature greater than 77
°
C (171

No =
GO to D4.
D3 CHECK COMPRESSOR TEMPERATURE AFTER COOLING
•
Open the hood and allow the underhood compartment to cool for one
Yes =
GO to D5.

D4 CHECK FOR COMPRESSOR OVERTEMPERATURE FAULT
•
Clear the continuous DTCs from the IAA module.
Yes =
GO to D5.
•
Operate the A/C system for five minutes and retrieve continuous DTCs
