Heat stresses batteries. Low or unstable voltage (often below 12V) can cause the ECU to report an internal "B101D30 ECU Malfunction" simply because it isn't receiving clean power.

Because low voltage is a primary trigger, check your battery health using a dedicated digital load tester. Ensure the resting voltage is at least 12.6V. If the battery is older than 2 years or fails a load test under cranking conditions, replace it immediately before trying to clear the ECU codes.
