Could a bad pcu lead to abs failure?
I have a 1997 honda accord ex. My check engine light came on recently and was then followed by my abs light and i no longer have anti lock brakes. I ran a scan on the check engine light and it said i had a bad torque converter, but i did some research on it and it stated that a common problem with my year is that the check engine light will come on stating a transmission fault when it's really just a PCU failure. so my question is if i replace my pcu will my abs begin working again, and has anyone else heard of my kind of problem?

Thanks i will run the scan again and get back to ya. but i know that the car shifts and runs perfectly fine plus i did a tranny drain and fill just to be safe.

Is this a 4 or 6 cylinder accord? Your ABS problem may be a different issue than the D4 light.
You can also short a service connector with a piece of wire or a thin paperclip and get the transmission code and the abs code. Your 97 will only have the two pin connector under the glove box in the instructions linked below. The D4 light will flash the transmission code. The ABS light will flash the ABS code.
See: dhost.info/accordinfo/howto/cel.html
For the D4 light, a long flash =10, short flash=1. So, LLL S = 41.
For the ABS light, the ABS light will turn on for 2 seconds, pause for two seconds. It will blink the main code quickly, pause for one second, then flash the sub-code. There will be a 5 second pause then the next code (or same code repeated) is flashed.

P0740 = lock-up clutch not engaging
(corresponds to a trans D4 flashing code of 40)
I'm not much of an auto-trans guru, I like to have 3 pedals on the floor. But I don't think this P0740 would be related to the ABS problem.
I think your 1997 still has the 2-wire OBD-1 connector even tho it also has the OBD-2 connector. So if you jumper that & follow the instructions PA gives, you can watch the ABS lamp for flashing an error code. Normal OBD-2 scanners (like AutoZone) won't read ABS codes.
