PTO VERIFICATION PROCEDURE
NOTICE: This procedure is only for vehicles equipped with a PTO. If the
vehicle is not equipped with a PTO, proceed to Step 28 following this
procedure.
PTO Verification
NOTE: For additional information on the PTO, refer to TT-17-004 COE PTO
installation.
With the ECU and VCS software update in this recall, adjusting engine idle
speed adjustment by use of the cruise control switch (when the vehicle is
not moving) has been eliminated. This change may impact customers who
were using the cruise control switch to control idle speed for PTO
use. Follow the three steps below to determine if installation of a PTO
switch, or modification of existing PTO switch wiring will be necessary.
1. Confirm the body application. If no PTO is present, proceed to Step 28
following this procedure. If the vehicle is equipped with a PTO, proceed to
step 2, below.
2. Using the DX2 monitor PTO status (PID 8). With the engine running,
engage the PTO.

Does the DX2 PTO status display “ON” when the PTO switch is on?
Yes: No further action is needed. The cruise control
switch will function as before to allow elevated
idle speeds when the PTO switch is turned on.
Proceed to Step 28 following this procedure.
No: Modifications are needed. Proceed to step 3, below.

3. For vehicles that have a PTO switch but the DX2 PTO status did not
display “ON” with the switch on, modifications are required to enable
elevated idle speed by use of the cruise control switch.

In order to use the cruise control switch to elevate the idle speed, the
Engine ECU must receive a switched 12 volt power signal to circuit %8H /
PTO SW1 (Red) when the PTO is in use. Also, item number 229 must be
set to “1” in the Engine ECU Customization Menu using DXII. Refer to
chapters 7 and 11 of the body builder book as well as Tech Tip 17-004 on
Hinonet to modify the existing PTO switch wiring.
After the ECU PTO signal has been wired in and item 229 is set to “1”,
recheck PTO operation. Verify that the “PTO ON” indicator illuminates
when the PTO is engaged, and the engine speed is adjustable with the
cruise control switch, or a preset elevated engine speed is reached. Once
proper operation of the “PTO ON” indicator and elevated idle speed is
verified, proceed to Step 28 following this procedure.
