tlgood Member Holiday Rambler Owners Club Join Date: Nov 2018 Posts: 77	Strange ABS codes on 2005 HR Ambassador The ABS dash light on my 2005 Holiday Rambler Ambassador 40 PLQ came on on our way back from Alabama. My diesel mechanic told me this morning that the active codes are "SID 151 - FMI 14", "SID 5-FMI 12", and SID 6 - FMI 12". Basically, the unit think that the left and right wheel sensors on the 3rd axle have failed. This unit has only 2 axles. Also, the rear modulator valve isn't clicking when you cycle the key like it should and the test button on the circuit board isn't blinking the codes. It just stays constant red. Attached Thumbnails
