      1. For the simulation test, reproduce the conditions that were present when the problem occurred. These conditions should be based on the customer's comments and freeze frame data that is recorded with DTCs, such as solar panel output voltage, solar charging battery SOC, solar charging system status, ACC terminal status, IGCT terminal status, solar charging battery block temperature and solar charging control unit temperature.
