DESCRIPTION

An A/C cut-off system is used to improve idle smoothness just after stalling the engine and to improve acceleration performance.

SYSTEM OPERATION

1. Warm up the engine to normal operating temperature and run it at idle.
2. Turn the blower switch and A/C switch ON.
3. Disconnect the throttle position (TP) sensor connector.
