My ABS light was on erratically, but now it's staying on. I pulled the codes this morning and got loads....
It's a '95 K2500.
21 - RF speed sensor/circuit open
22 - Missing RF speed signal
25 - LF speed sensor/circuit open
35 - VSS circuit open
66 - Open/shorted pump relay
73 - Memory error
86 - Shorted ABS indicator lamp
There's so many codes there I don't really know where to start! When I short the pins on the diagnostic connector I can hear the ABS pump run for 2 seconds.
Help!
