ECU Diagnostic Error?
 

so i was tuning the 20B yesterday and for no apparent reason, in the lower left corner of the halwin screen in a red bow appeared "ECU Diagnostic Error"

at first, it wouldn't let me adjust the bars in the fuel map (just what i happened to be messing with at the time, i didn't try other maps) so i restarted the laptop, and disconnected the car battery for a few minutes.

when i fired it all back up, the ECU Diagnostic error message was still there, but it would let me adjust the bars now.

that's where i stopped because i was unsure whether or not the adjustments i was making would even take place and i was unsure if it would be safe to even try to run the car with this error.

i read the manual (again) and found nothing. . . anyone see this before? what's to be done of it?

thanks

nevermind. . . faulty coolant level sensor

You connected your coolant level sensor to your Haltech?

Do you mean faulty coolant temp sensor.

So, the haltech was just telling you the coolant wasnt hooked up or bad?
