Sensor Error TCM
Shorted A or B
Heater RTD
If the error still occurs
with the hose FTS
unplugged, one of
the heater RTDs is
bad.
Unplug the A or
B RTD from the TCM. If
unplugging an RTD fixes
the T6DT error, replace
the RTD.
Bad RTD or bad
RTD placement
against heater
Swap A and B heater
output cables and RTD
cables and see if issue
follows. If so, replace
RTD.

element
Confirm resistance of
heater. Heater resistance
should be 9-12 Ω for 10
kW systems, 6-8 Ω for
15 kW systems, 4–6 Ω for
20 kW systems. If out of
tolerance, replace heater
element.
