Tuscan Diagnostics Codes

[RU1]

I've just got my Tuscan back after a one month visit to the dealer to have things sorted out. Unfortunately it still has a few problems . The main ones being the dash comes up with intermittent diagnostics codes the latest being Code L. Does anyone know what this means?

Also the inertia on the seat belts is way too sensitive - it takes 5 minutes of jiggling to get the things to unwind enough. Anyone know how to adjust them?

The diag codes on the FAQ here. The seat belt sensitivity is a TVR thing, I'm led to believe. They all do that sir.

Code L is - Erratic road speed sensor input. This usually means that the sensor, sited on the diff, is dirty. Older cars had the original sensor changed under warranty due to erratic readings.

[RU1]

Thanks very much for that. Hopefully the warranty will cover it if it comes up again. Will check the FAQs.

I just got my 1st code L today....AND low voltage 9.5 volts!!
I was begining to think something was wrong!!!

Sure this has been posted before, but here is a list as at November 2001

Thanks for you help guys.

Code has disappeared now although been replaced by a repeating frost warning - pressing the reset only stops it for a few seconds. It also locked me out today when I parked up (even though I had the keys in my hand! Climbing in through the back window in my office car park had the security guard out pretty quick!

Is this problem with the repeated Frost Warning code a common one ? I have just taken my Tuscan out for a quick 20 minute run (I was getting withdrawal symptoms after being away last weekend and no drive for 10 days !).

Outside temperature according to the display was 2C and the Frost Warning kept coming up again no matter how many times I pressed the diagnostics display switch to turn it off.

Quite distracting when it won't stay off for more than 30 seconds (especially as I'm still running the car in for its first 1000 miles and want to watch the rev counter like a hawk) !

Not on early models they only give a warning for low oil & water temperatures.

Yes, i've been driving with my thumb or forefinger ready to catch it, it's been reading frost warning for about two or three weeks now - last night at 23:00 it kept changing it's mind as to wether it was -1 or -2
and I was aware of it as we blatted (at times) back from the 'Bristol Beers and Pie'

..the road felt very firm...but difficult to keep it down though when you're in convoy with a Noble!!

[andyvdg]

The frost warning is a right pain in the ar*e when the temperature is hovering around 2 degrees. Funny how that Sunday Time journalist didn't pick up on this as a (the ?) genuine ergonmic design fault. Prat.

[trueblue]

Thanks Andy. So, I'll be putting that one down to another "they do that sir" design feature rather than adding it to my glitch list for the 1,000 mile service !

I spoke to the dealer about it as my dash was just upgraded due to the display faulting previously. Apparently the repetition is normal. I've resorted to turning the beeping right down now though as the display is distracting enough.
