New PDU Software - JTP 627/5
ISSUE:
New PDU software has been released.
^ JTP 627/5 replaces 627/4.
JTP 627/5 includes updates to previously released software issues and is a release of the S-TYPE software.
The CD contents list details all of the software that is available on this CD.
Note:
When entering a VIN for S-TYPE, you must enter the last 6 characters, not just the last 5 numbers. Without the letter, the PDU will interpret the VIN as an XK8.
CD CONTENTS (VEHICLE APPLICATIONS ONLY)
The above systems are supported with manual checks to the area only. Full down to wire guided diagnostics are not available.
EXCEPTIONS
The following S-TYPE Systems are not covered on this CD release:
Powerfeeds
Passenger compartment fuse box
Engine bay fuse box
Luggage compartment fuse box
Trailer tow fuse box
Auxiliary/ignition/start circuits
CHANGES
The following functions have been modified since the last release:
Integrity Test
It is now possible to disable the integrity test, reducing the overall diagnostic tic time.
Vehicle CM identification
This function is now available within the Vehicle Set-up.
CM CONFIGURATION
The PDU contains configuration software for a significant number of control modules (CM) on the S-TYPE. The following tables provide data on what level of configuration will be required under differing circumstances. The CMs will require configuring using the PDU in the case a service replacement is installed.
The control modules will require configuration in the event being fitted as part of an accessory kit.
The control module will require configuring in the event of DTCs C1277 and C1278 (steering wheel angle) being cleared.
VID BLOCK PROGRAMMING
The Vehicle identification block (VID block) is a section of memory within the powertrain control module used to store data about all of the control module configurations on the vehicle.This data is not used by the vehicle itself, and therefore failure to program the VID block will not affect the vehicle's operation. The VID Block data is used by PDU during its diagnostic and configuration routines to gather data about the vehicle.
PCM ID
The PCM Identifier is a unique code used to synchronize the PCM, Instrument pack and Steering column lock control module. If all three modules are not synchronized then the vehicle will not start.
NEW WARNING MESSAGE
A new general warning message has been added to the start of all diagnostic routines. This message will appear whenever the PDU is switched on or the diagnostic application is reloaded from the base station. Specific warning messages will still be provided within the diagnostic routines when required.
DIAGNOSIS OF CONTINUOUS CRANKING PROBLEMS
The starter test routine for S-TYPE provides diagnostic procedures for continuous cranking problems. Unlike the majority of other applications this routine assumes that the vehicle is not continuously cranking at the time the test starts. The test will operate correctly with either of the following two conditions applied.
^ Starter relay removed
^ Battery supply strap to the starter motor removed
ACTION:
Ensure that this software is installed immediately. Retain the previous issues in a secure place as a backup CD-ROM in the event the new software is damaged. Use JTP 627/5 for diagnosing 1995-97 MY Sedan Range, 1997-ON MY XK8, 1998- ON MYV8 XJ Series and 2000 MY S-TYPE.
Note:
When entering a VIN for S-TYPE, you must enter the last 6 characters, not just the last 5 numbers. Without the letter, the PDU will interpret the VIN as an XK8.
