Listing a model year does not mean every vehicle of it is concerned: the document says which.
| 01145820355193 | 2022-09-26. Service bulletin. The leak detection pump (LDP) is a vacuum-driven, ECM-controlled, diaphragm pump. In order for the LDP to operate, the engine must be running and vacuum must be applied to the vacuum switch on the LDP. The LDP pressurizes the EVAP system and monitors any pressure drop within a specified amount of time in order to detect a leak. |
