Scr torque derate.
Ran good, except the DREADED service DEF message see dealer came up on the EVIC. I called the dealer we bought it from and scheduled an appointment to turn on the heater, update the 8.4 radio and check out the DEF system like it says. Next day wife drove it to work 15 miles and parked it , went to leave and EVIC says 5 MPH in 150 miles.
Motor derate is a process in which a truck's engine cools off after reaching a certain threshold temperature. It limits the motor's power and torque to less than 75 percent of its rated power. The goal of limiting the derate is to minimize impact on the performance of the truck and to prevent forced shutdowns at reasonable effective grades.ClearTech ™ System.

To fit the 50A solar breaker, we can sometimes reduce the power rating of the main breaker. If we reduce the size of the main breaker to 100A, then we have 50A available to add solar. 100A main breaker + 50A solar breaker = 150A. This 150A follows the 120% rule, and a main panel upgrade has been avoided!Other common components of the SCR system that could cause the warning message include the Diesel Oxidation Catalyst (DOC) and Exhaust Gas Temperature (EGT) sensor. 3. Overheating. Another cause of the SCR system fault warning message is overheating. The temperature of the vehicle should always be monitored.The SCR system is an emissions control technology found in Volvo vehicles. It works by injecting a liquid nitrogen-based substance, known as diesel exhaust fluid (DEF), into the exhaust stream of a diesel engine. This reacts with the nitrogen oxides present in the exhaust and reduces the amount of harmful pollutants released into the atmosphere.Table 1 to Paragraph (a) (2) of § 1036.111 —Vehicle Categories. speed <15. 15 ≤speed <25. speed ≥25.
