I was wondering if anyone has fixed a chevy blazer with error code 1860? If so how do iI fix it?

Answer 1

B1860 - Driver Lumbar Vert Sensor Circuit Malfunction

This is the only reference that I can find with any code reference of '1860'.
The only assumption that I can make is that the Blazer has position memory seats for different drivers. Could be a sensor, the wiring or the body control module.
I would say its time for a dealer, if, in fact, this is the case.

Answer 2

If its just the 1860 code(some tcc solenoid electrical fault) you may just have to replace a wire or connector, then again the slenoid may be faulty. I am sure this code sets when the pcm detects an open or short on the tcc pwm(torque converter clutch, pulse width modulated) circuit. If you happen to have other codes and no speedo or tach, it may be a faulty ignition switch

Answer 3

For future reference for questions involving codes, you need to give the prefix with the code. If this is a code P1860, it will most likely involve a trans. slip or shifting problem was detected. If this is the case, all you can do is to check fluid level and condition. If these are good, you have a hard problem inside the trans. Other than that, you will need to visit a dealer or trans. shop. If this is not the right code, give the whole code and we'll try again. Good luck.
