Datsun 1600 HFS3-Help needed

[Richard L]

Good to know we have moved on a bit further.

To test if the system is reading the F-IDC or not, please do the folllowing:

1. Remnove jumper link "PRK"
2. put it on to "FDC"

Now the gauge will display the F-IDC on the gauge. Please let me know the result.
