ABS light on constantly. There is suppose to be a way to jumper pins on the passenger side connector. Mine has the triangle connector with a 2pin connector coming from that harness. Where do I jumper which connector to read the 2 digit codes? Thanks

Lol, wow I got off the side on that one, my bad, yes the ABS system light comes on when a wheel speed sensor goes out in most cases. On the connectors jump these two together:

Triangle connector: Pin E (top single pin)

Two-pin connector: Black wire (ground)

ABS Code Retrieval Procedure

Turn key OFF.
Turn key ON (do NOT start engine).

The ABS light will begin flashing two-digit codes:

Long flashes = tens
Short flashes = ones

After a pause, additional codes will flash.
Example: Flash... Flash... (Pause) Flash... Flash... Flash... = Code 23

Popular codes

Code 11 - Left Front Wheel Speed Sensor Fault
Code 12 - Right Front Wheel Speed Sensor Fault
Code 13- Rear Axle Speed Sensor Fault
Code 14 - Wheel Speed Sensor Signal Erratic / Intermittent
Code 15 - Mismatched Wheel Speeds / Out-of-range comparison
