Fault Code 7
Reason:
The resistance of the Evaporator sensor is outside the normal range (> 45K
Ohms).
Primary Action:
Check the sensor connection at the power module.
Secondary Action:
Replace the sensor.
Fault Code 8
Reason:
The resistance of the Evaporator sensor is outside the normal range. (<660
Ohms)
Primary Action:
Check the sensor connection at the power module.
Secondary Action:
Replace the sensor.
Fault Code 9
Reason:
The resistance of the PC sensor is outside the normal range (> 45K Ohms).
Primary Action:
Check the sensor connection at the power module.
Secondary Action:
Replace the sensor.
Fault Code 10
Reason:
The resistance of the FC sensor is outside the normal range (< 660 Ohms).
Primary Action:
Check the sensor connection at the power module.
Secondary Action:
Replace the sensor.
Fault Code 11
Reason:
The current measured for the ambient heater, PC fan and FC fan is lower than
expected.
Primary Action:
Check the 6-way fan/LAH RAST connector at the power module.
Secondary Action:
Re-terminate the 6-way fan/LAH RAST connector.
Tertiary Action:
Replace control module.
Fault Code 12
Reason:
The current measured for the ambient heater, PC fan and FC fan is higher than
expected.
Primary Action:
Check the 6-way fan/LAH RAST connector at the power module.
Secondary Action:
Re-terminate the 6-way fan/LAH RAST connector.
Tertiary Action:
Replace control module.
Fault Code 13
Reason:
Low ambient heater is drawing less current than expected. Either the heater or
wiring is open circuit or the heater is faulty.
Primary Action:
Check wiring and connections at both heater and power module.
Secondary Action:
Check low ambient heater resistance. If not within limits, replace.
Fault Code 14
Reason:
Low ambient heater is drawing more current than expected. Either there is a
short in the heater, or the heater is faulty.
Primary Action:
Check wiring and connections at both heater and power module.
Secondary Action:
Check low ambient heater resistance. If not within limits, replace.
Fault Code 15
Reason:
PC fan is drawing less current than is expected. Either the wiring is open circuit
or the fan is faulty.
Primary Action:
Check PC fan wiring and connections at both fan and power module.
Secondary Action:
Check fan. If faulty, replace fan.
