As reported in the last post, on very rare occasion, I noticed that the Parking brake indicator and the ‘BRAKE LAMP’ warning light stayed On immediately after turning the IG key into P2 but even before touching the brake pedal.
This will happen if you disconnect the right tail assy or if you have wiring or gauge assy issue.
Normally with the gauge issue, the first sign is the intermittent BRAKE LAMP warning even with good light bulb and I don’t think the parking brake circuit would be affected so decided to first check the 22pin grey connector at the forward left section of the boot behind the carpet.
With the state of the tail light assy gasket before replacing them with the new one, no surprise several terminals showed heavy corrosion. 2 x male terminal turned into green patina corrosion, 3 x female terminal lost the internal sprung force and making intermittent connection.
Polished the male terminals and replaced all three female ones with gold plated one.
However, all five were not related to the brake light (they were for the rear fog light, power ANT) and also I checked all of the terminals at the R & L tail light assys and none of them showed any issues……
I’m afraid the issue is the wiring issue somewhere on the car but most likely to be the gauge assy internal issue with leaky capacitor.
I can replace the caps but don’t have the jig to re-calibrate the speedo and rpm gauge so at this stage, can’t do much.
Without the brake disc, can’t do anything any further on this NSX so moving onto the next NSX.
