E00
Communications Error
Check all wiring to heater.
Reboot ECU by removing main fuse for 5 minutes.
Replace ECU as necessary
E01
Failed Ignition
(Two attempts)
Heater does not start successfully within start up period.
Refer to Combustion Issues in manual.
E02
Flame Extinguished
(Three successive failures)
Heater establishes a flame then detects a flame out condition.
Refer to Combustion Issues in manual.
E03
High or Low Voltage
Voltage at ECU must be less than 16.0 volts and more than 10.5 volts
Repair vehicle electrical system as required
E04
Premature Ignition

Unburnt fuel in combustion chamber during start up.
Refer to Combustion Issues in manual.
E05
Thermal Efficiency Failure
Heater detects a poor combustion
Refer to Combustion Issues in manual.
E06
Temperature Sensor Open or Short Circuit
Check sensor resistance.
Should be approximately 1.0 kΩ at room temp. Replace as necessary
