SSM 46790

Some 2017 E-Series vehicles with 6.8L engine may exhibit an illuminated MIL with multiple DTCs such as P1336 and/or P0339. This may be due to wire chafe near the air conditioning (A/C) compressor due to an unsecured wire harness tie-down strap locator. Before following normal diagnosis, inspect for wire chafe near A/C compressor. Repair any wire chafe damage following wiring repair instruction in the Wiring Diagram, Section 5-1. Attach wire harness tie-down strap locator to A/C compressor. For claiming, use causal part 12A581 and applicable labor operations in section 10 of the service labor time standards (SLTS) manual.
