E.C.C.S. DESCRIPTION
Air Conditioner Compressor Control (Where fitted)
The E.C.M., upon receiving an A/C request signal from the A/C
switch, activates the air conditioner compressor via the A/C relay.
Inputs from the thermo amplifier indicating high or low pressures, or
thermostat cut-out temperature has been reached will cause the
E.C.M. to de-activate the air conditioner.
Additionally, if the throttle is opened more than 60% and acceler-
ation enrichment is triggered, the E.C.M. will de-activate the com-
pressor for approximately
12
seconds or until the throttle is closed
to lower than
50%.
