Title: ABC, ET see, camera gone wild
Post by: Kevin Higgins on August 05, 2021, 04:21:42 PM

I’ve looked on other forms and have read issues with the ABS and the ATC light coming on.  The other day I was having the same issue my ABC light was on the ATC light was on and my Aladdin engine status was going crazy. The camera would come on without hitting any buttons and it would switch from right to left then rear. I would switch it back to engine status drive another 5 miles and the camera would start going crazy again. I pulled over checked all the fuses got back in the RV was getting ready to get the book out turned it on and all the lights were out everything is working normally. I’ve driven it about another hundred miles and everything is normal. I’m getting ready for a long trip and if it does it again was wondering if anybody has had this issue. Thanks

I have not had this issue myself - but read on the forum that a problem with the engine like a cylinder misfiring (or a loose/corroded electrical connector to engine computer causing a brief engine stutter,) can cause the ABS/ATC light to come on because the engine "miss" causes the engine/driveline torque to abruptly change. This torque-on, torque-off makes the ABS sensor think traction to a wheel is being lost. Did you notice any engine roughness during this time?

I'm not sure how/why the camera is being affected, except that the Aladdin does monitor the turn signal status (for switching camera view to side cameras) - and it is reading the engine data signals, so perhaps your problem is a due to a loose or dirty wiring connector.

Are you using an external data reader (like the ScanGauge D)?

From your description I'd be looking at the wiring diagrams to see where the camera system and the ABS/ traction control system come together IE  do they share a power feed or ground say at the front power distribution center .

Didn’t notice any power loss or mechanical issues. They did start happening one by one first the ABS light came on then a few moments later the ATC light came on and then the camera started going crazy. I just had a hydraulic line for the front steering box repaired I’ll see if there’s any wires in that area they disturbed.

The ABS and the traction control both use the same sensors and tone rings at each of the wheels to operate to cure this problem start by taping the sensors back in till they touch the tone rings on the hubs They will self adjust with bearing movement
The ABS problem you describe is 9 times out of 10 just too wide of air gap at the tone ring causing the sensor signal to drop out
The camera issue may be the Aladin system trying to alert of a trouble code or an electrical issue

I'd start with the ABS sensors and go from there.

Thanks everyone for the response, didn’t really find anything everything seems to be in working order checked the sensors everything looks good if it happens again and I figure it out I’ll report back thanks
