Attachment III - Technical Information

[NEW!] OVERVIEW

This program involves reprogramming the Powertrain Control Module (PCM) and the Transmission Control Module (TCM) with a performance enhanced calibration using IDS release 72.01A and higher. This calibration update also contains improvements to address the following symptoms:

^ Malfunction indicator lamp (MIL) illumination with false engine related DTCs P132B, P0299, PO5OE, and PO6EA

^ Wrench light illumination with false transmission related DTCs P0884, P0731, P0732, P0733, P0734, P0735, and P0729

^ Low speed, low load engine surge

^ Abrupt engine shutdown feel

^ High pressure (HP) fuel pump knocking noise at idle

^ Delayed diesel exhaust fluid level indication change after refill event

^ Harsh/bumpy transmission upshifts/downshifts

^ Delayed/harsh transmission engagement feel between Reverse-Drive and Drive-Reverse shifts

^ Transmission gear hunting during speed control operation when climbing grades or hills, particularly while towing

^ Erratic transmission operation in D (drive) after descending a grade with the gear shift lever in 1 (first)

^ Delayed current gear indication when using SelectShift mode

This calibration also contains the following enhancements:

^ Added SelectShift memory feature, so the SelectShift gear display will remain activated after shifting out of and back into D (drive) or after a key cycle

^ Added engine overspeed protection feature while descending long grades when towing and in manual gear ranges (forces transmission upshifts at 4000 rpm engine redline)

^ Increased torque during hill assist operation (see owner guide for additional hill assist information)

^ PTO operation improvements

- Automatic Secondary Electronic Idle Controller (SEIC) turns on at engine start if the switch is in the ON position

- Minimum engine coolant temperature to operate PTO is lowered to 20°F (-7°C)

- Improved RPM control with SEIC controllers

SERVICE PROCEDURE

Module Reprogramming

NOTE:
Reprogramming concerns! errors may be caused by the following:

^ Data Link Connector (DLC) or Vehicle Communication Module (VCM) becoming disconnected.

^ Allowing the IDS to enter any type of sleep mode.

^ Using a wireless IDS to VCM connection.

^ Low voltage on the IDS lap top.

^ Low voltage in the vehicle battery (use of a battery charger is recommended).

If you encounter reprogramming concerns, DO NOT DELETE the session. If the original session has accidentally been deleted, recover the original session from the IDS "TRASH CAN" (located in the lower right corner of the previous session screen) and continue to reprogram.

1. Connect a battery charger to maintain battery charge during this reprogramming procedure.

2. Make sure that all accessories (radio, interior fan, headlights, etc.) are switched off.

[NEW!] 3. Verify that the IDS is updated to software release 72.01A and higher.

4. Connect the IDS to the vehicle and start a session.

5. Select the Tool Box tab and then select Module Programming. Touch the tick.

6. Select Module Reprogramming and then select PCM. Touch the tick.

7. NOTE: If the IDS states there are no updates available, either the IDS has not been updated to an appropriate software release level, or the updates have already been performed.

A screen will appear stating a later PCM and TCM calibration is available. Follow the on-screen instructions to program the PCM and the TCM to the latest calibration.

NOTE:
Remind dealership service management that they must provide a copy of the Customer Information Sheet to the vehicle owner.
