WIPER PARK OPERATION: PARK SWITCH OPERATION: THE PARK SWITCH IN THE WIPER MOTOR IS INPOSITION #1 WHEN THE WIPERS ARE IN THE PARK POSITION. IT IS INPOSITION #2 WHEN THE WIPERS MOVE OUT OF PARK POSITION. WIPER PARK OPERATION: WITH THE WIPER ON/OFF RELAY IN THE OFF POSITION, THE PARK CIRCUIT HAS TWO POSSIBLE STATES: - WIPERS IN PARK POSITION: WITH THE WIPERS IN PARK POSITION, THE PARK SWITCH IN THE WIPER MOTOR IS IN POSITION #1. THIS CONNECTS THE WIPER LOW SPEED CIRCUIT TO GROUND, HOLDING THE MOTOR IN PARK POSITION (DYNAMIC PARK). - WIPERS OUT OF PARK POSITION: WITH THE WIPERS OUT OF PARK POSITION, THE PARK SWITCH IN THE WIPER MOTOR IS IN POSITION #2. THIS CONNECTS THE WIPER LOW SPEED CIRCUIT TO BATTERY POWER, MOVING THE WIPERS TO PARK POSITION.

WASHER OPERATION: PRESSING THE WASHER PUMP SWITCH INITIALLY ACTIVATESONLY THE WIPERS. THE WIPERS ACTIVATE AT LOW SPEED IF THE WIPER SWITCH IS IN ANY POSITION BESIDES HIGH. THEWIPERS REMAIN AT HIGH SPEED IF THE WIPER SWITCH IS ATHIGH SPEED. IF THE SWITCH IS HELD FOR MORE THAN 0.5 SECOND, THE WASHER PUMP WILL ACTIVATE AS WELL. WHEN THE SWITCH IS RELEASED, THE WASHER PUMP WILL STOPIMMEDIATELY. THE WIPERS WILL REMAIN ON FOR 1-3 SWIPES. THE WASHER PUMP WILL NOT OPERATE FOR MORE THAN 15 SECONDSCONTINUOUSLY.

WIPER INTERMITTENT & LOW OPERATION: WHEN THE WIPER SWITCH IS SET TO AN INTERMITTENT SETTING,THE WIPER MOTOR LOW OUTPUT (TERMINAL #9, CONNECTOR J105) WILL PULSE ON (GROUNDING THE WIPER ON/OFF RELAY) FOR 0.7SECONDS EVERY FEW SECONDS. THE INTERVAL FOR EACH SETTING IS: INTERMITTENT SETTING INTERVAL #1 4 SECONDS #2 7 SECONDS #3 12 SECONDS #4 20 SECONDS WHEN THE WIPER SWITCH IS SET TO LOW, THE WIPER MOTOR LOW OUTPUT IS STEADY ON.

WIPER HIGH OPERATION: WHEN THE WIPER SWITCH IS SET TO HIGH, THE WIPER FASTSWITCH, IN THE TURN SIGNAL SWITCH, GROUNDS THE COILS ONBOTH THE WIPER ON/OFF RELAY AND THE WIPER HI/LOW RELAY.

* CAB PDC HAS FUSES AND RELAYS LOCATED ON BOTH THE ENGINE SIDE AND THE CAB SIDE OF THE FIREWALL. ENGINE SIDE FUSES AND RELAYS ARE INDICATED BY AN "E" PREFIX AND CAB SIDE ARE INDICATED BY A "C" PREFIX.

USAGE: USE ON NGP CHASSIS WITH 12-12V ELECTRICAL AND NAMUX 4 INSTRUMENTATION AND 2010 EMMISSIONS COMPLIANT ENGINES.
