However, fault codes are stored in the engine control module (ECM). The fault codes occur at light load, between 8% and 14% accelerator pedal position. The programmed values for the misfire adaption are not automatically reset when the memory is deleted. The adaption must be reset after the engine is installed.
A011325 2035002-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. MIL on. DTCs are stored in the engine control module. The DTCs may appear during monitoring of the secondary air system during the engine cold starting phase. With the electric solenoid valves controlled, a diagnosis cycle is performed and the secondary air pressure is measured for a specified value. The secondary air pressure can be influenced by several factors; which may include a leak in the vacuum system or a faulty exhaust catalyst. Review the Service section of this bulletin for more information.
A191334 2028574-2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. Supersedes Technical Service Bulletin Group 19 number 12-29 dated February 7, 2012.

A171232 2018550-2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 12 - 31 dated August 30, 2012. Oil consumption measurement - Repair Authorization (CA). In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner's Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil.
