DIAGNOSTIC TOOL: PARAMETERS
Exhaust valve objective position: 0 - 100 %
NOTES: Value that the control unit sends to the
instrument panel to operate the valve: 0% (valve
closed), 100 % (valve open).
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
