A/C Signal: Description and Operation

The A/C clutch control relay:
- is integral to the constant control relay module.
- cuts off the A/C to improve idle smoothness after engine start-up.
- cuts off the A/C to improve acceleration performance.

The A/C field coil is cut-off for approximately five seconds just after the engine is started.

The A/C is also cut off when the Throttle Position sensor (TP sensor) indicates a wide open throttle condition.
