MATING P / N: P20-1132-1312 OVERCURRENT SITUATION:
F 13 O HEADLAMPS HIGH BEAM - 14A F
14 < SPARE > - LOW BEAM OUTPUT: IF THE LOW BEAM OUTPUT IS SHORTED, IS
15 S HAZARD LAMP ON / OFF LOW 14mA CONNECTED TO BULBS WHICH ARE RATED ABOVE 65 WATTS PER
SIDE, OR FOR SOME OTHER REASON DRAW TOO MUCH CURRENT, THE
16 O HEADLAMPS LOW BEAM - 11.5A OUTPUT WILL SHUT DOWN AND THE HIGH BEAMS WILL ACTIVATE AT
17 < SPARE > REDUCED INTENSITY. AFTER 1 SECOND, THE LOW BEAM OUTPUT WILL
18 S IGNITION ON / OFF HIGH 14mA REACTIVATE. IF THE PROBLEM IS GONE, THE LOW BEAMS WILL REMAIN
( 6.19 ) ACTIVE AND THE HIGH BEAMS WILL SHUT DOWN.
19 * P HEADLAMPS LOW BEAM - 11.5A IF THE PROBLEM PERSISTS, THE LOW BEAM OUTPUT WILL AGAIN SHUT
20 G MODULE GROUND - 300mA DOWN. THIS CYCLE WILL HAPPEN AT MOST FIVE TIMES, AND THE
21 S SWITCH COMMON LOW 1A FINAL STATE WILL BE HIGH BEAMS ON.
E - HIGH BEAM, TURN / HAZARD AND TURN / HAZARD / STOP OUTPUTS: IF E
12-WAY CONNECTOR THE HIGH BEAM OUTPUT, OR A TURN / HAZARD OR TURN / HAZARD / STOP
1 G MODULE GROUND - 300mA OUTPUT IS SHORTED, IS CONNECTED TO TOO MANY BULBS ( SEE
2* P MODULE BATTERY - 1A NOTE # 12 AND TABLE A ), OR FOR SOME OTHER REASON DRAWS TOO MUCH
CURRENT, THE OUTPUT WILL SHUT DOWN. AFTER FIVE SECONDS, THE
3 S HEADLAMPS HI / LOW CYCLE LOW 14mA OUTPUT WILL REACTIVATE. THE OUTPUT WILL ATTEMPT TO REACTIVATE
4 P HEADLAMPS HIGH BEAM - 14A EVERY FIVE SECONDS UNTIL THE PROBLEM IS FIXED.
