Switch Performance Check

Switch must be checked in ON (closed) and OFF (open) positions. Switch should function as follows:

• ACS Switch is closed when A/C is on and blower is operating.
• BLMT Switch is closed with fan selector switch is in 2nd, 3rd or 4th position.
• CCPS Switch is closed with A/C on and system pressure within normal operation range.
• HPS Switch is closed with A/C on and system pressure exceeding normal operating range.
• IDL Switch is open when throttle is depressed.
• CPP/PNP CPP switch is closed when clutch pedal is depressed. PNP switch is closed when transaxle is in Neutral.
• PSP Switch is closed when system pressure is high (turn steering wheel sharply with engine on).
• WOT Switch is closed when throttle is wide open.
