display shows no data - ZR-1 Net Registry Forums

Well i was going to take the car for a ride this morning but when i started
the car the display showed no data. Now the car started and ran fine, at one
time the display showed all correct data. The next time all i get is a blank
display , i cannot display any codes. After checking the service manual i see
that the CCM will show code 31 no display or data.They say remove cluster
and check for B+ short to gr. It could be the CCM causing the tbl. So should
i pull instrument panel first and go from there. Checked ECM no tbl codes.
Either way i'll have to pull something out.
Thanks
John
