PTO VERIFICATION PROCEDURE
NOTICE: This procedure is only for vehicles equipped with a PTO. If the
vehicle is not equipped with a PTO, for 16MY-18MY vehicles, proceed to
the Label Installation Procedure. For 19MY vehicles, proceed to the
Owner’s Manual Update Procedure.

PTO Verification
NOTE: For additional information on the PTO, refer to TT-15-027
Conventional PTO installation.
With the ECU and VCS software update in this recall, the engine idle
speed adjustment by use of the cruise control switch (with vehicle
stationary) has been eliminated. There may be an impact on customers
who were using the cruise control switch to control idle speed for PTO
use. Follow these steps 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, for 16MY-18MY
vehicles, proceed to the Label Installation Procedure. For 19MY vehicles,
proceed to the Owner’s Manual Update Procedure. If the vehicle is
equipped with a PTO, proceed to step 2, below.
2. With the engine running, engage the PTO.
Does the “PTO ON” indicator briefly illuminate in the instrument cluster
(meter) after turning the PTO switch on?
Yes: No further action needed. The cruise control
switch will function as before to allow elevated
idle speeds when the PTO switch is turned on.
No: Modifications are needed. Proceed to step 3, below.

3. For vehicles that have a PTO switch but the “PTO ON” indicator does
not illuminate in the instrument cluster (meter) 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 A6N /
PTO SW1 (Yellow) 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 15-027 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.
Confirm proper operation of the “PTO ON” indicator and elevated idle
speed is verified.

LABEL INSTALLATION PROCEDURE
NOTICE: 19MY vehicles DO NOT require label installation. For
19MY vehicles, proceed to the Owner’s Manual Update
Procedure.
1. To comply with California regulations, an emissions certification label
must be applied to the fan shroud. As shown in the photograph at the right,
open the hood and clean the area of the fan shroud, using brake parts
cleaner and a clean rag. The fan shroud surface must be clean and dry
before affixing the label.

2. Verify that the information on the new label exactly matches the
information on the existing valve cover label. DO NOT remove the existing
label on the valve cover. Make certain not to bend or wrinkle the new label
during handling. Apply the emissions label to the fan shroud as shown in
the photograph below, on the right. Close the hood and engage the hood
latches. Proceed to Owner’s Manual Update procedure, below.

OWNERS MANUAL UPDATE PROCEDURE
1. Affix the “NOTICE” label to the back side of the cover page on the
owner’s manual.

2. Place the supplement guide in the vehicle with the owner’s manual to
alert the operator of the changes to the cruise control idle up feature and
exhaust brake at idle deletion. Proceed to the Repair Label Installation
Procedure, below.

REPAIR LABEL INSTALLATION PROCEDURE
1. Once all above steps in this recall procedure have been completed,
apply a recall label to the left door jamb above the VIN label. Fill in the
Campaign No, Dealer code, and Repair date. Proceed to the Final
Inspection Procedure, below.
