What I did was to Press "Check Control (C/C)
" before switching to "on" and kept my finger there -Reading is Temperature.
Then switched to "on" whilst depressing the accelerator pedal;
Quickly Release C/C then re-Press, C/CReading changes to CHECK CONTROL OK
Pump Accelerator 4 times and release
Whilst still depressing the C/C button (Do not release it)
Then I got lines grouped in sequences of 1,2,3 and 4.
Wrote them down counting how many lines each series contained.
My reading is 1/3/4444444/2/1/4444/3/44/1/33/44 . What it means boggles my mind.But am still surfing for explanation.
