@Christopher Assal I decided to install a Kill Switch in my car (Nissan Patrol Y61) because:
- ABS would kick in frequently, for example when stopping to maintain distance with the car in front, to avoid an obstacle, when crossing over a crest and heading down a slope, etc. This scenario led many times to a situation where the ABS light would remain on for a long period even after the drive.
- I used to pull out the ABS fuse, but this would disable the VDC switch, the speedometer and the odometer.
The mechanic who installed the Kill Switch did it in a way that disables ABS only and would not affect the other gauges, he also checked there were no diagnostic trouble codes. The VDC is something I can control in my car, I feel the car runs better when I disable it, and I only enable it if I am attempting recovery from a stuck in 4H. In the Patrol when you engage 4L and Diff Lock then ABS and VDC will be disabled by default.
The only fuse I remove is the airbag fuse, because I've heard of cases where the airbag could deploy if there is a frontal hit, and I've had quite a few already during drives. **Edit: a few frontal hits on the area where the bash plate is mounted 😅, usually the result of a miscalculation, speed, or wrong reading of terrain.
My recommendation is you try, in your next drive, removing the ABS fuse and assess the performance of your car and if there is any effect in the speedometer and odometer, also check what light indicators turn on the dashboard when you disconnect the fuse and when you engage 4L. Depending on what you observe then you take a call whether to install or not a kill switch.
Hope this helps!
