Code# Fault Description by System Family Troubleshooting Actions and Comments
03 NC Wash hose pump over current Check Pump motor M8 wiring for problems (+ BLU and - BLU/RED).
Check pump motor for short circuit (spec XA) replace as needed. Test
current draw 12.5A full load max @12V.
19 NC Horn over current Check H4 horn wiring for problems (+ ORN/GRN and - WHT/YEL). Check
horn for short circuit (spec 4A@12V) replace as needed.
17 NC Back Up Alarm over current Check optional back up alarm wiring for problems (+ ORN/GRN and
- BLU/BLK). Check horn for short circuit (spec .25A at 12V, electronic
alarm) replace as needed.
02 C Main power relay K1 coil over current Check K1 relay coil wiring for problems (+ ORN/GRN and - BLU/GRN).
Check coil resistance; less than 36 ohms - replace. Also see main power
distribution electrical ladder detail. (Spec .29A@12V) replace as needed.
25 C 20A Circuit breaker CB1 over current Control board has sensed open circuit fault for CB1 power for head/tail
and turn signal lamps. Check for GRA/RED wire shorted to ground.
26 C 20A Circuit breaker CB2 over current Control board has sensed open circuit fault for CB2 power for mist pump
(M5) and (M8) wash hose pump. Check for Blue wire shorted to ground.
27 C 15A Circuit breaker CB3 over current Control board has sensed open circuit fault for CB3 power for side broom
actuator motor (M7). Check for Violet wire shorted to ground.
28 C 20A Circuit breaker CB4 over current Control board has sensed open circuit fault for CB4 power for hydrau-
lic solenoid manifold coils (L4-L 11). Check for Orange wire shorted to
ground.
29 C 10A Circuit breaker CB5 over current Control board has sensed open circuit fault for CB5 power for hydraulic
solenoid manifold coils (L1, L2 and L3) also PumpsM4 and M6. Check for
GRN/BRN wire shorted to ground.
20 NC Left turn signal lamp over current Check left turn signal wiring for problems (+ YEL and - BLK). Check lamp
for short (see the I/O table for circuit spec).
21 NC Right turn signal lamp over current Check right turn signal wiring for problems (+ GRN and - BLK). Check
lamp for short (see the I/O table for circuit spec).
22 NC Head and tail lamp over current Check head and tail lamp wiring for problems (+ BRN, YEL/RED, ORN/
BLU and - BLK). Check lamps for short (see the I/O table for circuit spec).
23 NC Left stop lamp over current Check left stop lamp wiring for problems (+ ORN/BRN and - BLK). Check
lamps for short (see the I/O table for circuit spec).
24 NC Right stop lamp over current Same as left stop lamp just different wire color (+ YEL/RED and - BLK).
14 NC Glow plug relay K4 coil over current Check K4 relay coil wiring for problems (+ ORN/GRN and - WHT/ORN).
Check coil resistance; less than 36 ohms - replace. Also see diesel glow
plug starting circuit electrical ladder detail.
