5.3-3 LED Error Codes - Code Breakdown Chart
Diagnostic sequence dependant on LED flash code:
No Last Caldate
63
Load Not Calibrated
62
Height Not Calibration
61
An EZcal is required!
Waiting For Neutral
55
Drive/Lift Inputs Faulty!
56
Up/Down Select Inputs Active ogether
54
EMS Inputs Faulty!
52
Check inputs on P2 pins 1,2,3,4,5,6,7,8.
P3-4 Short o Supply!
42
P3-4 Short o Supply?
44
P3-6 Short o Supply?
46
Disconnect plug P3. If fault clears there is a problem with the wiring from P3-4 or P3-6 to the rest of the vehicle.
Armguard Active!
23
Elevation Switch Shifted?
21
Elevation Switch Stuck?
22
If the 23 flash code is triggered by armguard, it will occur once then clean. his is not a true fault but just an indica-
tion of the reason for the vehicle stop. If the 21 or 22 flash code is triggered by a fault with the elevation switch, it
will not clear. Check that the elevation switch correctly opens/closes when the platform is raised/lowered.
P3-4 Short o 0V?
43
P3-6 Short o 0V?
45
Disconnect plug P3. If fault clears there is a wiring fault from P3-4 or P3-6 to the rest of the vehicle.
Invalid Load - Check Sensors
45
Check the voltage out of the pressure transducer, into P4-2. It should be between 0.5V (zero pressure) and 4.5V
(maximum pressure) and should vary as the platform load & position varies.
Waiting For B+ on P2-12
52
B+ Supply oo Low
51
P4-1 Or P5-1 Short o 0V?
41
Check that the battery voltage is not too low.
Verify battery voltage on P2-12.
Disconnect plug P4 – if the fault clears there is a wiring fault from P4-1 to the rest of the vehicle.
