Fault-Tracing Information

Fault-tracing

Checking the status




- Start the engine.
- A/C on.
Read the diagnostic status and trouble status for the diagnostic trouble code by selecting the diagnostic trouble code in the list.
Check if the malfunction is permanent or intermittent by reading off the diagnostic trouble code's status when the diagnostic status is "Implemented".
If the trouble status is "Malfunction found", this indicates that the malfunction is permanent. If the trouble status is "No malfunction found", this indicates that the malfunction is intermittent and not active right now.

Note! Trouble status cannot go from "Malfunction found" to "No malfunction found" in the same operating cycle.









Continue - Replacing the component

-------------------------------------------------

Replacing the component
Engine control module (ECM) has registered that the A/C pressure sensor is damaged.
If the malfunction is intermittent, it has been registered previously but no longer remains. Intermittent malfunctions can be due to disruption when the control module started or can be another type of malfunction that may recur at different instances. If the malfunction is permanent it means that it is active right now. The malfunction is assessed on a case by case basis.
Remedy as necessary.
