I got a 94 Honda Civic Ex that came stock with all 4 wheel ABS. Now, I had the ABS light on for a while and ignored it because lazy me, I don't have time to fix it. So finally today I went to go and check the codes on it and shows that it's blinking 1/2 second fast of 4 and 8 times. So in other words, 4 comes up first and then 8 comes last. Any suggestions and help would be appreciated???

Insert the jumper, then turn on the key.
Long (2sec.) flash - long (2sec.) pause - this isn't the code yet.
Short flashes for the first digit of the code - 1sec. pause - short flashes for the 2nd digit.
Long (5-second) pause, then the next code

(94-97) ABS DTCs...
1 - ABS pump motor over-run
1 2 ABS pump motor
1 3 high pressure leakage
1 4 pressure switch
1 8 high pressure system
2 1 parking brake
3 1 pulser RF
3 2 pulser LF
3 4 pulser RR
3 8 pulser LR
3 12 different diameter tires
4 1 wheel sensor RF
4 2 wheel sensor LF
4 4 wheel sensor RR
4 8 wheel sensor LR
5 - rear wheel lock - R/L
5 4 rear wheel lock - R
5 8 rear wheel lock - L
6 - fail-safe relay - F/R
6 1 fail-safe relay - F
6 4 fail-safe relay - R
7 1 solenoid - RF
7 2 solenoid - LF
7 4 solenoid - R
8 1 ABS function
8 2 CPU comparison
8 4 IC self-check

There's NO long flashes, it's all short flashes with short & long pauses in between."


4 8 wheel sensor LR

start by inspecting the sensor & isolating problem:
a. dirt & grime could be clogging the sensor
b. if there is any malfunction, replace the part
c. excessive looseness or play of the ABS wheel-speed sensor
d. deformation of the ABS wheel-speed sensor
e. deformation or damage of the ABS sensor rotor
e. using a multimeter, inspect the resistance

 

Thanks man...i actually finally found the same forum as you did just now. Okay.....well, the thing is that I remember replacing the trailer arm bushings on my car and did manage to take a look at the rear wheel speed sensors and it did have some little chip in it. So, I'm wondering maybe like you said that it would be the wheel speed sensor??? However, I'm probably gonna try to bleed the ABS hydraulic unit first to see what happens.

 

Looks like a LR wheel sensor. Good Luck!
