Hello out there guys. i have a problem with my Abs system in my camaro lt1 95,i got some codes out from 9495 scan.
44,Left front abs channel will not move.
46,Rear abs will not move.
is this the solenoids in the pump or what??
Sorry for my English i'm from Sweden best regards Ronnie

I am curious as to the Codes 44 and 46

I thought Code 44 was Bank 1 (left) o2 sensor , lean

and Code 46 was PASS-key II circuit

Did you get a Brake or ABS INOP light on the dashboard ? If you did, do they Stay Lit, or Flash ?

Did you check the ABS fuses under the hood #1 and #5 ?

Here is a link to the Codes that I am aware of....

Hi yes i got the brake light. probably abs light to,but i think someone tamper with the light. so it wont light up. the codes i found in the workshop manual. they should be correct.the same as those in 9495 scan program the fuses is ok

Here are 2 links with Codes that indicate the 44 and 46 don't represent what you are indicating. What workshop manual are you using ?

GM 93-94 5.7L VIN P ? OBD/OBD2 Trouble Codes

OK, I just found where you got your Code info from. The 1995 Service Manual, page 423, Section 5E1-22. And it shows just what you indicated. Sorry about my confusion.

Hopefully someone else with more knowledge will jump in here to help you out.

Thanks anyway

If you haven't already, maybe try checking all of the ABS connections. At the ABS motor, and at each wheel, to verify that the connectors are not loose, corroded or damaged.

Do you have access to the 1995 factory service manual? If not, free download here:

ABS DTC 44 is shown on page 5E1-94 (page 495 in the pdf).

ABS DTC 46 is shown on page 5E1-98 (page 499 in the pdf).

No expert here, but looking at the code descriptions, there are three possible causes of each code:

ESB = Expansion Spring Brake. A spring used to hold the modulator piston in the upmost (or "home") position.

ABS Motor

ABS Hydraulic Modulator - pulses the individual braking circuit whan ABS activated.

I realize not a lot of help here, and maybe you already have the factory service manual, and know everything posted above. Just wanted to make sure you have the info, in case you didn't.

hi yes i have downloaded that manual.and read what you wrote about. i do not feel like take the abs module apart. but i wonder if i can put 12v direct to the abs and try to force it to start. thanks so much for the help

Found a pump on eBay in Miami. they shipped it to Sweden. that solved the problem for me.

Would have suggested that, rather than trying to tear your unit apart. I have never seen anyone attempt that. But I had no idea if that was even possible for you to import used parts, working from Sweden.

Glad you got it worked out, and thanks for following up.
