$SSHQGL[ % *ORVVDU\ A/C: Air Conditioner A/D: Analog to Digital A/F: Air/Fuel ratio. The proportion of air and fuel delivered to the cylinder for combustion. For example, an A/F ratio of 14:1 denotes 14 times as much air as fuel in the mixture. A typical ideal A/F ratio is 14.7:1. ABS: Anti-lock Brake System AC Clutch Relay: The PCM uses this relay to energize the A/C clutch, turning the A/C system on or off.
