ECM fault code 168-1 indicates low battery voltage to the Engine Control Module, causing shutdown and electrical failures. This comprehensive guide covers diagnosis, repair steps, and prevention for diesel RV owners experiencing this critical issue.
Handle RV flat tires on the interstate. Covers safe procedures, who to call for motorhome tire service, and why regular roadside help may not work.
Holiday Rambler fenders can be sourced from REV Group parts department, RV salvage yards, or fabricated by fiberglass shops. The recurring detachment indicates a mounting flaw - reinforce attachment points during repair.
Drill mounting solar Z brackets is more secure than adhesive, especially for larger panels. Use proper Dicor sealant on all penetrations. Adhesive can fail in extreme temperatures.
ZF front suspension on Tiffin Breeze has known shock inadequacy. Koni upgrade from Tiffin helps significantly. If still bottoming, add Sumo Springs as progressive bump stops. Check for worn bushings, ball joints, and verify front axle is not overloaded.
Boiling battery with sulfur smell means severe overcharging or internal short. Disconnect immediately - hydrogen gas is explosive. Battery must be replaced. Check converter/charger output voltage before installing new battery to prevent recurrence.
Use CAT or Cummins dealer locators, truck stop service centers (TA/Petro), and RV apps like Allstays. Call ahead to verify they can accommodate RV size. Truckers use similar resources - diesel expertise overlaps between trucks and motorhomes.
Two batteries using more water indicates failing cells or connection issues. Check terminal tightness, measure voltage during charging on each battery, and test specific gravity. Higher voltage on some batteries indicates internal resistance. May be warranty issue at 6 months old.
