6103142018-11-13. Service bulletin. ELECTRICAL SYSTEM. Check Control Messages Related to Battery Charge During Cold Ambient Temperatures. On cold days with an outside ambient temperature of less than 15°F, customers may notice a check control message related to the battery that is displayed on the instrument cluster and the control information display. Under these conditions, the vehicle starts. Various power management faults can be stored: * 213901 - Power management: Reduction or shutdown of individual electrical consumer * 8040BD - Reset or deactivation of Terminal 30F * 8040B9 - De-activation of terminal 30B: Top start capability limit reached * 8020E8 - Reset or deactivation of terminal 30F * 800E89 - FRM: start capability limit reached with lights active during stationary mode * 93076B - Deactivation of terminal 30B: upper start capability limit reached * 93076A - Deactivation of terminal 15: upper start capability limit reached, but deactivation preventer active * 93076C - Deactivation of terminal 30B: upper start capability limit reached, but deactivation preventer or legal loads active * 930769 - Deactivation of terminal 15: upper start capability limit reached Note: When the outside temperatures drop below 46°F, the charging system is switch to full charge. CAUSE * The check control message (ID 229) is caused by a heavily discharged battery. * The check control message is triggered when the current state of charge (SoC) of the battery approaches the minimum SoC that is required to start the vehicle (start capability limit). * In low outside ambient temperatures, the start capability limit of the vehicle is higher. Therefore it takes more energy from the battery to start a cold engine. * Without the early warning of the check control message, the current state of charge would drop below the start capability limit and the vehicle would not start. * The vehicle's intelligent power management system actively takes measures to increase the charge of the battery, such as increasing idle speed and reducing or shut

B6523162018-11-05. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. ?AUDIO VOLUME NOT RESTORED AFTER MSA STOP, ENTRY HEAD UNIT. Volume of audio system (when set to near maximum) is reduced when Auto Start-Stop (MSA) stop occurs and is not restored upon automatic engine restart. This is normal system behavior - serves to protect the head unit, battery drain and avoidance of incremental leaps in the loudness. The loudness is reduced to 2/3 of maximum and is not restored. Note: Air conditioning output is also reduced upon MSA stop and is not restored for similar reasons.
B0703142018-11-05. Service bulletin. ELECTRICAL SYSTEM. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits This Service Information bulletin supersedes SI B07 03 14 dated October 2015.. Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
