Input Tests: Notes

WARNING: This page is about a different car, the 1991 Honda Civic and 1990 Honda Civic. However, it is still accessible from the selected car via links, so may be relevant.

Remove the dashboard lower panel and dash fuse box, then disconnect the 10-P connector from the integrated control unit. See Fig 1 . Remove the integrated control unit from the dash fuse box.

Make the following input tests at the harness pins. If all tests prove OK, yet the system still fails to work, replace the control unit.

NOTE: Several different wires have the same color. They have been given a number suffix to distinguish them (for example BLU/WHT¹ and BLU/WHT² are not the same).
