- How the car detects it
- For C0822 the search of code lists, NHTSA and the GM, Saab and Mitsubishi sources returned nothing. Per its title it covers the rear left level sensor of an air suspension. At the rear axle the harness runs close to the subframe and fuel tank, which is where Stellantis found the cause of its own code C1526 subcode 11, short to ground, on a 2019 Grand Cherokee: the wiring rubbed on bracket edges and had to be repaired, isolated and tied away (STAR S2108000161). On the 2022-23 Ram 1500 the same sensor sets C1526-2A when the module considers it stuck. HELLA notes that many such sensors work with two redundant channels, so the module can spot a split between them before the reading is used.
