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

The airbag module will flash out the trouble codes through the airbag warning light on the dash.

Step 1 - Turn the Key ON

Don’t start the engine, just turn it to RUN. The airbag light will come on solid then go off, each code is a two-digit number:

First digit = number of flashes before a long pause
Second digit = number of flashes after the pause

Example:
Flash-flash-flash... Pause... Flash-flash
= Code 32

Code Meaning
12 Low battery voltage / recent power loss
13 Airbag circuit short to ground
21 Safing sensor not mounted / open circuit
22 Safing sensor short
32 Driver airbag circuit high resistance (clock spring issue)
33 Driver airbag circuit open (bad clockspring)
42 Primary crash sensor feed open
44 RH front crash sensor fault
45 LH front crash sensor fault

Please let me know what code you have.
