How difficult is it to replace this unit, have an abs light on, and didn't kick in when some assface cut me off and this happened

JKLedbetter · 03-04-2019, 04:49 PM

Not tremendously difficult.

But how do you know the problem is the modulator?

Well when I slammed the brakes super hard , the pedal didn't kick when abs is working and light is always on and don't. Blink

If ABS light is on, it in inoperativ. You need to pull code to determine the issue.

IamPlan_B · 03-05-2019, 07:49 PM

I tried connecting the jumper to connect but its not blinking, so I tried the other plug down there and still nothing. I know one is for ecu .

IamPlan_B · 03-12-2019, 07:28 PM

Tried to pull codes with jumper wire on service connected in kick panel. If I start engine with jumper on I get check engine light on, abs off. If I pull it off abs comes on and engine light off.
Either way I get no blinking abs for codes
I also check fuses in engine fuse box, and get nothing out of Alb 1

What am I doing wrong or what else can I check for . I was going to buy a ass ecu from yard, but didn't want to spend 70 on it if that's not the problem

I'm not sure if it works the same for the G2, but in the G1 the ABS computer is mounted behind the back seat on the (USDM) driver's side, which requires you to open the trunk and look through a flap in the trunk liner in order to see the ABS codes.

Abs computer on g2 is passenger side behind rear seat back. There are two service connectors on pass. Kick panel , one for engine ecu and other is for abs ecu.

Update, was able to get the abs light to start blinking code after trying a different jumper wire. After key on it blinked 3 times with 2 seconds in between each blink.

The codes can be found here: http://www.atfinley.com/service/inde...&z=2690&r=0666 My guess is that you are getting code 1, pump motor overrun.

Yep, pump/modulator is defective.
