GMballistic Posted March 16, 2018 Share Posted March 16, 2018 Moved to a more appropriate sub section area. It's been along time now since I had my Zed but I believe you just hold the button down that you use to cycle through once you see the average MPG pop up. It should just clear and then leave "- - -" until you've driven some more for it to recalculate. Hopefully some members with Zeds still will confirm 100%.

GrahameJ Posted March 16, 2018 Share Posted March 16, 2018 Just fitted some UK gauges to my JDM model, so as I could now see mpg rather than litres per whatever, I then tried to reset the mpg. 1) Cycle through using the top left button until mpg shows. 2) Press and hold the lower button until the gauge reading starts flashing and then resets to nulls (dashes). 3) Drive for a mile or so and then the new mpg figures will display. Hope this helps There is still one function that does not work, which looks like it may be a clock, currently just flashing showing nulls(dashes) when I cycle to it. Can anybody confirm if there is a clock on UK models, and will a UK heater control module be needed to get this working? 1 Quote Link to comment Share on other sites More sharing options...
Willsy1980 Posted March 18, 2018 Share Posted March 18, 2018 On the uk ones there is usually: mpg, dte, clock, temp, lap time and speed. Think that's them all iirc Only ever use the clock and DTE Quote Link to comment Share on other sites More sharing options...

Willsy1980 Posted March 19, 2018 Share Posted March 19, 2018 (edited) No worries, willy was close but willsy is better btw, I missed the rev limit indicator setting too.. Full list is: clock speed outside temp DTE average fuel consumption and speed elapsed time Stopwatch trip odometer Shift indicator light It may be an ecu thing . Here is an archive on the same topic: Edited March 19, 2018 by Willsy1980 Quote Link to comment Share on other sites More sharing options...

Here is an archive on the same topic: Apologies - Willsy! It could be ecu related, although the average mpg on the UK gauges does match my actual mpg calculated manually, as I always fill to the brim and check the mileage from the trip on the speedo. Digging around in the US service manuals shows the triple gauges are controlled by the heater air-con module, so looks like I need a UK version of that too to get the clock working! Anybody know the part number? US Manual for 2004: UNIFIED METER AND A/C AMP PFP:27760 System Description AKS00955 For the unified meter and A/C amp., the signal required for controlling the combination meter and triple meter are integrated in the A/C auto amp.

Bridgey Posted March 22, 2018 Author Share Posted March 22, 2018 Thanks everyone for your help. You guys were right. The reset switch is the button under the computer trip, mpg etc scroll button, that you keep pressed in for a couple of seconds 1 Quote Link to comment Share on other sites More sharing options...
