Fairtax4me Posted June 18, 2013 Share Posted June 18, 2013 The module will flash a code 11 as a start code before flashing any stored codes. I've checked abs codes before and the module doesn't pause for long between codes. Are you sure you're not getting a code 11, and a code 26? I can't find a code 46 listed anywhere either, but I only have info for US market vehicles. I do see 26, 36, and 56. But no 46. Quote Link to comment Share on other sites More sharing options...
john in KY Posted June 18, 2013 Share Posted June 18, 2013 Check all the tone rings for cracks. A cracked tone ring will trip a code. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 19, 2013 Share Posted June 19, 2013 ABS is sensitive to system voltage too - maybe give the charging system a thorough check. Quote Link to comment Share on other sites More sharing options...

It still looks like 46 but I know what you mean..I just posted a short video with 11......46...11.....46. I really can not see any gaps, but there maybe. Let me know what you think. abs fault codes(1).wmv Quote Link to comment Share on other sites More sharing options...

1 Lucky Texan Posted June 19, 2013 Share Posted June 19, 2013 I THINK some older ABS pumps used to go bad, but, IIRC, they would 'buzz' all the time. I think the ABS controller had to be replaced. However, my memory associates that problem with models a year or 2 earlier than yours so, I'd reserve replacement for a last-ditch effort.

dollinn Posted June 22, 2013 Author Share Posted June 22, 2013 I have checked the voltage and everything is ok. Also now checked the electrical properties of the g sensor, abs sensors and everything is correct. Still have no idea what is causing the 46 code in the video above. I removed the abs controller from under the dash and everything looks ok. The unit is a 5.3 system Bosch hydraulic unit and nippon abs controller. Does anyone have a pin-out for the connector in this picture. It differs from the service manual. I can not find any info anywhere on it.

dollinn Posted June 25, 2013 Author Share Posted June 25, 2013 1996 legacy abs.pdfThanks everyone for your help. It turns out abs fault code 46 does exist. The service manual for the 1996 model shows it is a g sensor power fault. I have checked and the sensor is damaged. See manual attached.

idosubaru Posted June 25, 2013 Share Posted June 25, 2013 that is a nice document, thanks. where is the G sensor located? i didn't see it listed? i have some ABS codes...and i think 46 may be one of them, i'll have to recheck. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 25, 2013 Share Posted June 25, 2013 G sensor is under the center console.you can almost see it through the park brake handle opening. Take the two screws out of the rear section under the arm rest and pull it up, the G sensor is the little box with 3 or 4 wires. Quote Link to comment Share on other sites More sharing options...
