Cause
P10AE81 may be generated in OBD13 and newer chassis. The code may show to be in
Active or Inactive status and cannot be cleared if Active. P10AE81 may or may not be
accompanied by P105817 and P105818
This fault is intended to prevent unintended movement that could result from a related
mechanical failure in the gearbox.
P10AE is generated when the Gearbox status is reported as Neutral, but the countershaft
to mainshaft gear ratio results in speed signals that indicate that the transmission is NOT
in neutral when the clutch is engaged. The active fault will cause the following
symptoms:
- Red STOP Lamp will be illuminated
- If the vehicle is running when the fault occurs, the gearbox will not shift and
will keep the clutch disengaged.
- If the vehicle is shut down with the fault active, a no crank / no start condition
may be observed if gearbox air pressure is too low when trying to restart the unit.
Solution
DO NOT PROGRAM THE TECU TO TRY TO RESOLVE THIS
FAULT
1. If P10AE is ACTIVE and the engine will Crank and Run
Main symptom: The clutch will remain disengaged if a gear is selected via the gear
selector
1.1. Allow the unit to idle for 30-45 seconds.
1.2. Check the status of P10AE81.
1.2.1. If the code is still active after idling: The gearbox should be investigated
for possible mechnical issues
1.2.2. If the code is inactive after idling: The code in this case was a ghost or
intermittant fault. Items in Section 3 should be reviewed to confirm there are no
other issues that need to be addressed.
2. Operate the vehicle if possible to evaluate mechanical condition.
3. Review the DTC Readout and follow the appropriate steps below:
3.1. If P10AE81, P105817 and P105818 all appear on the DTC Readout and are
setting at the same time: Replace the ribbon harness, proceed to Section 4.
3.2. If P10AE81 is logged separately: Inspect for mechanical failure
3.2.1. If mechanical failure is noted: Repair as required. (A true mechanical
cause for this fault will likely never pass the monitor and allow the fault to
become inactive)
3.2.2. If there is no mechanical issue present: Replace the ribbon harness and
proceed to Section 4.
• NOTE: High counts of P10AE81 with no indication of a mechanical issue
make the internal transmission harness the likely cause.
4. Once the issue(s) has been corrected:
4.1. Start and idle the truck for 30-45 seconds.
4.2. Confirm P10AE81 is inactive.
4.3. Clear all of the inactive faults
4.4. Road test and release the vehicle to service.
