FAULT CODE / TROUBLESHOOTING
EW13 Warranty Process requires an Edith extraction printout to record codes before proceeding. Remember to carefully document the Complaint – Cause and
Correction.
000 - NORMAL OPERATION
1. No Repairs needed.
010 - OVER-VOLTAGE
1. System maximum voltage is 16 volts.
2. The possible causes of this code are (non-warranty).
a. A battery charger in boost mode.
b. Alternator overcharging.
3. Clear the code repair as needed
011 - UNDER VOLTAGE SHUT DOWN
1. System minimum voltage is 10.5 volts.
2. Verify battery voltage.
3. Install the Y interface adapter.
4. Connect the multi-meter to the red and brown wires and set to volts DC.
5. Record the voltage
6. If the voltage is less than 12.6 (ooded cell) 12.8 (AGM) connect the battery charger and log off the job until the batteries are fully charged, otherwise
continue below. (See note on page 11)
7. Turn on the unit while watching the multi-meter.
8. If the voltage remains above 10.5 clear the code, no repairs are needed, otherwise continue below.
9. Troubleshoot the tractors wiring harness utilizing the factory manuals – check for voltage drop to the heater.
10.Clear codes when repaired.
012 - OVERHEAT AT OVERHEATING SENSOR
1. Sensor has detected excessive temperatures.
2. Using shop air, blow out the heat exchanger and airow ducting including the heating air intake.
3. Check airow ensuring the ducting is free from obstructions especially the bunk inlet and outlet.
4. Check ducting rating of the installed heater. See page 33.
5. Remove the sensor, check connections, wiring and reinstall.
6. If the wiring is damaged or connection is corroded, replace the sensor, otherwise continue below.
7. Clear code and run unit.
8. If code returns replace the sensor.
9. Clear code and run unit ensuring issue is resolved.
013 - OVERHEAT AT FLAME SENSOR
1. Flame sensor detects excessive temperature at heat exchanger.
Using shop air, blow out the heat exchanger and airow ducting inclu ding the intake.
2. Check airow ensuring the ducting is free from obstructions especially the bunk inlet and outlet.
3. Check ducting rating of the installed heater. See page 33.
4. Remove the sensor, check connections, wiring and reinstall.
5. If the wiring is damaged or connection is corroded, replace the sensor, otherwise continue below.
6. Check fuel pump angle and correct if needed.
A. If correction was needed, clear the fault and run unit.
7. If fault code doesn’t return complete the job, otherwise continue below.
8. Measure fuel quantity.
a. Disconnect the fuel line from heater
b. Turn the unit on (remember 60 second delay prior to pump activation)
c. Place the fuel line into the graduated cylinder and allow to run through a rst start attempt.
d. Once fuel pump stops running from rst start attempt turn the unit off
e. Measured fuel must be between 3.5 to 4.3 milliliters. If the reading is high and the pump angle is veried correct, replace the pump, clear the codes,
run the unit, otherwise skip to step 16.
9. If fault code doesn’t return complete the job otherwise continue below.
10. Replace the sensor
