com port confusion

[dave]

i have some diagnostic software on my laptop that connects via a serial port.
the hardware came with a usb to serial adapter.
i have installed the driver for it but device manager says its now com18. but my diag software will only let me select com ports from 1 to 8 :bang:

how do i fix that delete and re install driver and hope it get assigned a different port number?

thanks

Is there an option within device manager to change the port number? Older versions of Windows used to allow this, at least up to XP, but I've not needed to try on Win7 or 10.

its an old xp laptop but i did not see that option

edit just googled changing com port number in xp and found answers, but laptop is at my unit so cant check

Hopefully what you've found will fix the issue.
I no longer have a working XP machine, but Win7 (best Windows ever in my experience) allows this:
Plug the ELM in.
Open Device Manager. Should see an option of 'Ports (COM & LPT)' Expand this to see your ELM.
Right-click your ELM, choose 'Settings', then 'Port Settings' and 'Advanced'.
The current Com port should be in a box with a drop arrow, which should give a list of ports to choose from.

that was it thanks for the help. i have no idea how i missed the advance tab before. got it all working and got into ecu to access fault codes but still none the wiser

Trip Code: 1502 105 occurrences Solenoid Brake Trip
Trip Code: 4401 20 occurrences Internal Control System Trip
Trip Code: 0E08 1 occurrences Throttle Trip
Trip Code: 3D02 5 occurrences Motor Wiring Trip
Trip Code: 3B01 45 occurrences Motor Disconnected
Trip Code: 0A00 14 occurrences Control System in Sleep Mode
Trip Code: 2F01 10 occurrences Throttle Displaced at Power-up
Trip Code: 1E08 188 occurrences Off-Board Charger Connected

the ones to worry about are in bold, ive bench tested motor and that seems fine, i will whip electric brake off and give it a test

Interesting set of codes, but need a context to better understand. A fresh thread perhaps?
Are these ABS system issues?

 

[dave]

no for a Kymco Maxi XLS.

Good luck finding fault code explanations for that. How's your mandarin?

TPS would get my vote as first place to look.
