Bluebulldog Posted April 5, 2022 Share Posted April 5, 2022 Seems this truck doesn’t like the changing of the seasons. After our fight with oil pressure blink codes last fall it ran all winter with no issues. Today’s problem is while driving the traction light eliminates almost immediately you get a electrical malfunction light and it shuts down. Just that fast it comes back leaves no time to check a blink code. Will it store faults for a dealer to check with out it being on currently?

JoeH Posted April 6, 2022 Share Posted April 6, 2022 It should, there's Active and Inactive fault codes. Active trip the light, inactive are stored faults that were an issue but are not currently. Or at least that's my understanding on the ETECH motors. No idea what year/model you're dealing with though. Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted April 6, 2022 Share Posted April 6, 2022 the codes are stored, "in-active" traction control should start with MID 136... 'ABS system' im curious why it is shutting down? what other symptoms do you have prior to it shutting down? jojo Quote Link to comment Share on other sites More sharing options...
Bluebulldog Posted April 6, 2022 Author Share Posted April 6, 2022 Nothing. I m going to watch this morning yesterday it would shut down going down the road the malfunction light would come on and before you could do anything about it everything was back. When I pulled in the drive I see the traction light was on. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 6, 2022 Share Posted April 6, 2022 Humm... mabey you have 2 issues, is the antifreeze full/ above the sensor? I just dont recall traction control causing a 'shutdown' jojo Quote Link to comment Share on other sites More sharing options...
Bluebulldog Posted April 6, 2022 Author Share Posted April 6, 2022 If I pull abs fuses will it shut traction control off? Water is full and the malfunction light shut down is connected to the traction light some how. Only does it when it’s on! Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 6, 2022 Share Posted April 6, 2022 I think it will shut it off.. did you try to flash the ABS codes? the switch is under the dash, next to the steering column. it is an orange lighted switch.. Quote Link to comment Share on other sites More sharing options...
Bluebulldog Posted April 6, 2022 Author Share Posted April 6, 2022 I see the switch what will it do if I switch it to abs. Had to pull the fuses to get load off this morning. Quote Link to comment Share on other sites More sharing options...
Bluebulldog Posted April 6, 2022 Author Share Posted April 6, 2022 (edited) Traction light comes on and get a 1-1 blink on the abs light. Wish I hadn’t have done that now I have abs and trac light and can’t get them off. Delivered load and put the fuses back in the abs ran home 25 mi with only seeing the traction light just a instant then out an no problem.

Onyx610 Posted April 6, 2022 Share Posted April 6, 2022 (edited) Sounds like you have a short to ground and going to need to start wiggling wires/connectors to get it to reoccur Edited April 6, 2022 by Onyx610 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted April 6, 2022 Share Posted April 6, 2022 (edited) Now a 1-1 blink code for the EECU is for EOP. You mentioned you had problems with that in the past. That will shut it down Edited April 6, 2022 by Onyx610 Quote Link to comment Share on other sites More sharing options...
Bluebulldog Posted April 6, 2022 Author Share Posted April 6, 2022 (edited) The 1-1 is the abs light after pushing the abs switch left of the steering wheel. had it hooked to laptop there are no active or inactive codes in it so going to run it till it quits. Can’t fix something that isn’t broke at the moment 🤷 Edited April 6, 2022 by Bluebulldog Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 6, 2022 Share Posted April 6, 2022 bad grounds is quite possible.. research Mack bullitens for a 9-2 code.. that gives a good procedure for fixing the grounds... jojo Quote Link to comment Share on other sites More sharing options...
JoeH Posted April 7, 2022 Share Posted April 7, 2022 My MR had a loose fuse for the VECU that caused a 9-2 (I believe that's engine power loss without key off) had to tighten the fuse connectors to get better contact. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 7, 2022 Share Posted April 7, 2022 yep, power reset without the key... its like leaving the key on, and unhooking the batteries while everything is powered up.. it will throw 9-2 code.. look at fuse 40 or 41 in the fuse box under the hood.. that is the eecu fuse.. jojo Quote Link to comment Share on other sites More sharing options...
