The resistance of all the temperature sensors is outside the normal range. (< 660
Ohms).
Check the 6 way RAST connector at the power module.
Re-terminate the 6 way RAST connector.
Replace the power module.
The resistance of the FC sensor is outside the normal range. (> 45K Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The resistance of the FC sensor is outside the normal range. (< 660 Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The resistance of the evaporator sensor is outside the normal range. (> 45K
Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The resistance of the evaporator sensor is outside the normal range. (< 660
Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The resistance of the PC sensor is outside the normal range. (> 45K Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The resistance of the PC sensor is outside the normal range. (< 660 Ohms).
Check the sensor connection at the power module.
Replace the sensor.
The current measured for the ambient heater, PC fan and FC fan is lower than
expected.
Check the 6 way fan/LAH RAST connector at the power module.
Reterminate the 6 way fan/LAH RAST connector.
Replace the power module.
The current measured for the ambient heater, PC fan and FC fan is higher than
expected.
Check the 6 way fan/LAH RAST connector at the power module.
Reterminate the 6 way fan/LAH RAST connector.
Replace the power module.
Low ambient heater is drawing less current than expected. Either the heater or
wiring is open circuit or the heater is faulty.
Check wiring and connections at both heater and power module.
Check ambient heater resistance. If not within limits, replace.
