... on the bench.
While I couldn’t move well with my back injury last week, it was good excuse for bit of R&D time for another owner.
Pretending to be all four wheel speed sensors connected, IG1 & IG2 configuration, R-C circuit charge/discharge I/F, brake pedal, etc and looking into some of the driver I/F circuit.
After understanding the I/F and driver circuit, modified my NSX ABS upgrade loom with extra pre-caution using separated terminals before connecting the full system.
As long as installed within the cabin and within the rated current spec, no extra heatsink required.
There are other know-hows to cover all year models but operation was fine and to be sure, carried out error code erase procedure involving the IG Sw, brake pedal, SCS terminal and confirmed the short two blinks of ABS light after the erase process so it's working.
Although there is no TCS controller involved for this ABS modulator, on the bench, each 4 terminals looked to be not floating so would love to monitor the output using my NSX on whether the I/F circuit for the level converted 4 x wheel speed signals were left without being disabled by the software.
Back to NSX....
