A/C Inhibit Mode
Parking Brake Input
The following conditions must be met before the
091-84-ETM64 controller will initiate a fast idle mode:
1. Engine Running at idle speed
2. No vehicle speed
3. Automatic transmission in PARK
4. Service brake not depressed
5. Accelerator pedal not depressed
6. Parking brake set (hardwired input from switch, or
default to engine data bus message)
Due to an inherent speed instability in the GM engine
controller during fast idle operation the 091-84-ET64
controller disables air conditioner operation during fast idle
operation. A terminal (”ACON”) is provided that when
wired to +12 volts will override the A/C disable and allow
the A/C to operate during the fast idle mode. In this mode
the engine speed will momentarily drop every time the
A/C compressor cycles on or off.
A terminal (”PK BRK”) is provided that allows a hardwired
connection to the parking brake switch. This can be used
if the vehicle configuration does not provide a data bus
message for the parking brake sensor status (e.g.,
Chassis with a non-GM instrument cluster). With no
connection to the PK BRK terminal the system will default
to use the data bus message for the fast idle interlock.
Or, the terminal can be wired to the parking brake switch,
which applies a ground to indicate that the parking brake
is applied.
