2. Wait for the heaters to cool.
3. Remove the lower covers (57, 58).
4. Disconnect over-temperature switches (214) from
cable (49). Test across the spade terminals with an
ohmmeter.
a. If the resistance is not approximately 0 ohms,
the over-temperature switch needs to be
replaced. Proceed to step 5.
b. If the resistance is approximately 0 ohms,
inspect cable (49) to make sure it is not cut or
open. Reconnect the over-temperature switch
(214) and cable (49). Disconnect the cable from
the TCM. Test from pin 1 to pin 2 and pin 3 to
pin 4. See
on page 69.
If resistance is not approximately 0 and
switches are 0, replace the original cable with a
new one.
5. If the over-temperature switch fails the test, remove
screws and discard the failed switch. Apply a thin
layer of thermal compound 110009, then install a
new switch in the same location on housing (201).
Secure with screws (215) and reconnect the cables.
