A.2 Control Program Proble ms

Haltech Programming Software will not start up

The Haltech programming software should run on any computer that meets the requirements

in Chapter 2.2.1. If, after following the instructions in Chapter 2.2.1, the program will not run,

the most likely cause will be insufficient memory. If this is the case, y ou must make more free

memory available before running the software.

Do not try running the Haltech software from within a shell program - always start from the

DOS prompt. If y ou are loadin g 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 comp uter 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 Programmin g software requesting infor mation,

Wrong Programmin g Disk (i. e. disk does not match ECU)

If the disk is the wrong version or you suspect that the cable is faulty, contact your Haltech

If the air temperature sensor, or coolant temperature sensor is showing a FAULT condition

then the sensors are either not operating correctly or are disconnected. Using the wiring

diagram of the Haltech F10 Loom check that the sensor wires are not damaged. If the wiring
