A.2 Control Programme Problems
Haltech Programming Software will not start up
The Haltech programming software should run on any computer that meets the requirements
in Chapter 3. If, after following the instructions in Chapter 3, the programme will not run, the
most likely cause will be insufficient memory. If this is the case, you must make more free
memory available before running the software.
Do not try running the Haltech software from out of another shell programme - always start
from the DOS prompt. If you are loading a number of TSR (Terminate and Stay Resident)
utilities during boot-up, you may need to disable them before running the Haltech software.
Refer to your computer and DOS reference manuals on memory management.
Alternatively, you may make your Haltech disk bootable by placing it in floppy drive A: and
typing:
c:\> sys a:
We recommend that you make a backup of the original disk before trying this. You should
then be able to restart your computer with the disk in drive A:, and the Haltech software will
load and run automatically.
If the software still does not run, and you see the message "Error ### at xxxx:xxxx", record
these numbers (or letters) and contact your Haltech dealer.
Haltech Programming Disk will not run Online
If the Haltech ECU does not respond to the Programming software requesting information,
then the message RECONNECT HALTECH will be displayed. This situation will occur
under the following conditions
• ECU is not powered up
• Programming Cable is not connected
• Incorrect COM port selected - see Chapter 13
• Wrong Programming Disk (i.e. disk does not match ECU)
• Programming Cable is damaged
• Serial port of programming computer is faulty.
If the disk is the wrong version or you suspect that the cable is faulty, contact your Haltech
dealer.
