TSB 07-17-3 6.4L - PCM UPDATE - BUILT BEFORE 7/30/2007 - INTERMITTENT P0342 AND/OR P1336, UPDATE - PTO FUNCTION, TURBO PROTECTION, HIGH IDLE, SHIFT QUALITY AND IC

FORD: 2008 F-Super Duty

This article supersedes TSB 07-16-2 to update the Action required.

ISSUE:
Some 2008 F-Super Duty F-250-F-550 vehicles built before 7/30/2007 and equipped with the 6.4L engine may exhibit one or more of the following concerns:

• Intermittent P0342 or P1336 powertrain control module (PCM) reprogram prior to normal Powertrain Controls/Emissions Diagnosis (PC/ED) Diagnostics)

• Loss of stationary elevated idle control (SEIC) or battery charge protection (BCP) during power take-off (PTO) operation when body is rolled or wheels are rocked

• Turbocharger bearing failure due to very cold ambient temperatures, frozen turbocharger actuator with diagnostic trouble code (DTC) P132B at temperatures below freezing

• Unacceptable engine idle RPM ramp rate at cold engine temperatures/cold ambient conditions in Neutral/Park with foot off Brake/Clutch

• Unacceptable engine idle RPM ramp rate during diesel particulate filter (DPF) regeneration in Neutral/Park with foot off Brake/Clutch

• Transmission upshift quality, engagement duration or feel, and shift busyness or powertrain hunting

This calibration update also includes diagnostic and malfunction indicator lamp (MIL) operation improvements for P200E, P242D and P2033. Follow normal PC/ED diagnostics for symptom or DTC identification.

This calibration also includes instrument cluster (IC) message centre updates for distance to empty (DTE) reads in reverse on dual fuel tank applications, "Engine Warming" turbo protection and "Stop Safely Now" exhaust over temperature warnings.

ACTION:
Reprogram the PCM, Transmission Control Module (TCM), and IC (Reprogram the IC by selecting Module Reprogramming, IC) to the latest calibration using IDS release 50.7 patch 10. When reprogramming the PCM on automatic transmission equipped vehicles the TCM will also automatically be reprogrammed to the latest level. This new calibration is not included in the VCM 2007.7 DVD.

Please print/copy the Customer Information Sheet attached to this Technical Service Bulletin (TSB) and insert it into the glove box Owners Guide for future customer reference.
