Cause/Notes
Two or more keys continuously pressed for 10
seconds or touch pad assembly has more than
one bad key. Key actions are suspended and
heating is paused. Error will clear and normal
operation will resume when no touch pads are
depressed.
TCM board or connections to TCM are bad.
During start-up, the control module is unable
to set TCM option code. Reset is required to
clear error.
A short to Vcc is detected in an encoder switch
for more than 10 seconds.
Temperature sensor disconnected or has a
faulty connection. Cooling fan will operate at
high speed and heating will stop. After two
consecutive temperature readings are made
successfully, heating will resume and error will
be cleared. See Communication Schematic.

Enter Service mode to set correct option
code.
Check connection to control module.
Check connection to TCM.
If unable to set option code and
connections are good, replace front panel
assembly.
Check all connections and wires to
temperature sensor.
Check resistance of temperature sensor: if
sensor tests OK, could be control module
problem; if sensor fails, replace sensor.
Check wires and connections for pinch or
short circuit to ground.
Check resistance of temperature sensor: if
