If the traction value does not increase or decrease as expected,
perform the following steps:
1) Place an order for the following part: Traction Encoder (ICE
Part Number: 8350266), Traction encoder cable, Down trunk
Harness.
2) Send any photos, notes, and/or a filled out Troubleshooting
Checklist to Brain Corporation using the e-mail address
specified in the work order.
3) Schedule the next site visit based on the tracking information
for the part.
4) Disconnect the traction encoder cable from the downtrunk,
and connect the new encoder directly to the downtrunk.
a) Spin the axle clamp to allow movement to be
registered by the BCM. Refer back to the Software
Diagnostic Traction Check section to view Traction
Reading.
i) If the traction encoder reading does not
change, replace the Downtrunk Harness and
repeat step 4a.
ii) If the traction encoder reading does change,
un-tether the traction encoder cable and plug
it into the new traction encoder and attempt to
get a traction encoder reading.
iii) If a reading is registered with the new encoder,
then replace the existing traction encoder (use
a gear puller if necessary).
iv) If a reading is not registered, replace the
traction encoder cable.
b) If the traction encoder reading does change after
replacing the downtrunk, then disconnect the new
traction encoder and plug the connector back into the
existing traction encoder cable. [Troubleshooting
complete]
c) If the traction encoder reading does NOT change after
replacing downtrunk harness, the BCM will need to be
replaced (refer to solution code BCM-01).
