the car is a 1994 accord ex, and now the abs light is on on the instrument cluster. the pump no longer turns on when the key is switched over like it always has in the past.

one question i have is, do obdI cars have abs trouble codes?
the reason i ask is because i jumped the service check connector and no codes appeared, the light remained solid. after looking in a haynes manual it says nothing about abs codes.
brake fluid levels are fine, and when i cracked the bleeder screw on the modulator there is no pressure, i have replaced the modulator thinking it was faulty but even still no bueno. any other ideas, i thought perhaps a faulty abs computer? but that doesnt seem too likely..

any thoughts?

 

There is a 2 wire connector at the ABS unit that goes to the pump motor, try jumpering battery power straight to that and see if the pump runs at all. The relay for the unit pump motor is in a small fuse box on the passenger side fender wall, you can pull those fuses to erase the ABS control unit memory.

 

yeah, i will try that. oh and yeah, all fuses ok. not sure if maybe a faulty relay is the cause..

 

ok, so i jumped the abs modulator directly to the battery, and it comes on. i replaced the abs relay located in the abs fuse box and still, it does not work. all fuses ok, and brake fluid levels ok. any other ideas?
