In order for an engine to run smoothly and efficiently, the combustion
chamber must be free of leakage. An
engine with low compression in one or more cylinders is inefficient and will run
rough or lack in performance.
Low compression may or may not cause the MIL to illuminate.
Low compression ca
Before A/C efficiency test, satisfy following conditions:
1. Provide a MoDiC or DIS. Safeguard electrical system integrity by checking
the fault memory (no faults
in the fault memory).
2. Provide a thermometer with separate gauge.
3. Perform the test in a suitable work bay with an ambient temperat
