ABS light Honda passport 97 by walterdgm

Where can I find the connector for reading ABS codes?
I only find a 16 pin connector left side (not OBD2), I don't have diagnostic hardware. Can I do it only sending to ground the connector?

Out of curiousity, how have you arrived at the conclusion that you need a new ABS module? Did you do a code check on the vehicle and if so, what was code(s)? Module is expensive and bleeding the system can be problematic if not done in proper sequence, would hate to see you get in over your head if module is not source of problem.

By rear anti lock brake light, do you mean you do NOT have the 4 wheel anti lock, just the Rear antilock version? Also, do you have automatic trans?
There is a diagnostic link for the brakes located behind the left kick panel. If the ABS light is on, a code is probably stored.
The light illuminates also when the Parking brake is on ..checked that? or the brake fluid level is low. Once those are checked, and if abs light is on, then code should be set. the rear wheel anti lock system is different from the 4wal, so more info is needed to be more specific.

Maybe their question can help with my initial question to this post(check page 1 of the post). My trooper has automatic transmission. The picture I posted on the first page should be the same cables that are on the 94 Trooper. They are under the front left kick panel below the steering wheel right above the hood release. Do you know which of the plugs is for the ABS? If so, how do you jumper it to read the ABS codes? Thanks for maybe a glimmer of hope. I had all but gave up on this problem.

here it is
my rear anti brake light is on and my brake light.
my back wheel is locked like it is dragging
i checked the fluid and that is all good.
i have a automatic trans..
i just bought this trooper 3 days ago and dont know much about it yet
this all happened when i changed the tail light and had my daughter hold down the brake pedal to see it the light worked.that is when i seen the lights in the dash were on and then i checked my brakes by driving backwards and then forwards and noticed it was locked and dragging

Hi again, the connector is a 3 wire and is jumpered as follows, and is found as described previously. The jumper must be installed and then the ignition turned on afterwards. ABS light should display two digit code If only 12 code flashes with no other codes, then it means no other codes stored
 
With IGN OFF, connect #1 terminal with #3 terminal (GND). Then turn IGN ON.
Keep #1 terminal connected with #3 terminal (GND) during DTC display. (If #1 terminal is separated from #3 terminal (GND) during display, display will stop.)
 
How To Erase Code: Connect and disconnect jumper wire between #1 terminal and #3 terminal (GND) at least 3 times within 30 seconds.
There is no time limit to "opening", but "each grounding" must be more than 1 second and the entire 3-grounding sequence must be completed within 30 seconds.

OK, is the parking brake off now and adjusted so that the switch is set properly?
I would have to wonder if the caliper itself is locked, and causing the combination valve to signal uneven brake pressures to the ecbm.
You could try a hard application of the brakes while moving forward and then backwards to see if the caliper unfreezes, but that is unlikely and not a fix, as it will likely just lock up again if that is where the problem lies. You should inspect brake tubes and hoses for pinch or kink, and then check the abs connector as described in this thread. If you get a code other than 12, post again and I will try to find it. Good luck
