- - Abs codes (https://honda-tech.com/forums/honda-accord-1990-2002-2/abs-codes-2694608/)

Hi everyone! So I have a 1993 accord ex 4 door. I was wondering if anybody has or knows a place to get a list of abs codes for my car. I am getting codes 2-1 and 4-8. I think 4-8 is the left rear sensor circuit but not sure about 2-1. Thanks in advance for yor help!

That link is for ECU Diagnostic Trouble Codes (DTCs)

You do it the exact same way you would for jumping the ECU codes. The SCS connector is a blue two pin connector under the glove box. Short that and count the flashes from the ABS light, not the CEL.

Here is a list of ABS codes,

1 The hydraulic pump motor is over-run
1-2 The hydraulic pump motor
1-3 Is a high pressure leak
1-4 The pressure switch
1-8 Accumulator of high pressure system
2-1 Circuit of handbrake warning lamp switch
3-1 Rotor teeth damaged on right hand front wheel speed sensor
3-2 Rotor teeth damaged on left hand front wheel speed sensor
3-4 Rotor teeth damaged on right hand rear wheel speed sensor
3-8 Rotor teeth damaged on left hand rear wheel speed sensor
3-12 Combination of different sizes of tires
4-1 Circuit of right hand front wheel speed sensor
4-2 Circuit of left hand front wheel speed sensor
4-4 Circuit of right hand rear wheel speed sensor
4-8 Circuit of left hand rear wheel speed sensor
5-4 Right hand rear wheel lock
5-8 Left hand rear wheel lock
6-1 Front fail safe relay
6-4 Rear fail safe relay
7-1 Right hand front, hydraulic modulator solenoid valve
7-2 Left hand front, hydraulic modulator solenoid valve
7-4 Rear, hydraulic modulator solenoid valve
8-1 Operation of the ABS
8-2 The ECU
8-4 Internal circuit of the ECU

Hope this helps :beer:

Thanks! Those should help me out. Thing is, I replaced the left rear sensor less than a year ago!

Check the wiring to see if it may have been pinched/cut by something. Also check the connection to make sure it hasn't come loose or become fouled with dirt/grime.

Check the resistance of the sensor itself. You should see 600 - 900Ω between the sensor connector pins.

So it read over 1000? Bad one? Even though its pretty much brand new?

Yes sir that would be a bad one. Yeah it sucks eh!

Was it an OEM Honda part or an aftermarket store part?

It was from napa. I had to do a couple other things on the car that day. one involved the check engine light from the coolant temp sensor and unfreezing my windshield washer fluid tank which wasn't fun. So i reset the codes by disconnecting the battery. I don't know if something was possibly frozen in there or what, but the abs and brake lights haven't been back on for a few days now...Also topped off the brake fluid. Any other useful info? I am thinking I should have bought one from honda. oops.

If you speed up and hit the breaks hard does the ABS system still kick in? I just had to replace the ABS LF wheel sensor on my wife's Grand AM. The ABS light would come on every now and then and then stay off for weeks at a time. Until finally the sensors signal was constantly out of the working range for the ABS computer. The ABS and traction control system shut itself off, sort of an ABS limp mode.

That could be similar to what is happening to you but then again maybe not. All you can do is keep an eye out for the ABS light.

Well with winter here now, i have tested the abs. When I hit the brakes when the roads are snowy/icy, i can hear the module working and feel the abs working, and no lights came on:) Right before it snowed, I had a deer cross the road in front of me and had to slam in the brakes. Abs worked flawlessly with no lights. So we will see. Thank you very much for your help and input! It is appreciated!
