Environment Error: Valid temperature difference between μC1 and μC2 exceeded

Was bedeutet 7 ?

When LED Diag 1 is off and LED Diag 2 flashes with code 7 (400ms ON / 400ms OFF), it indicates that the temperature difference between microcontrollers μC1 and μC2 has exceeded a valid threshold. This environment error could point to uneven cooling, a sensor malfunction, or an internal fault causing one μC to heat differently than the other, potentially compromising the integrity of dual-channel temperature monitoring.

• Significant temperature difference between the two internal microcontrollers (μC1 and μC2).
• Uneven heat dissipation within the device.
• Faulty temperature sensors associated with μC1 or μC2.
• Improper mounting leading to thermal gradients.

1. 1

   Read internal temperature readings for μC1 and μC2 from diagnostic parameters (e.g., P7-01, P7-02).

2. 2

   Ensure adequate airflow around the device to equalize internal temperatures.

3. 3

   Verify the integrity of the device's thermal paste or heat sinks.

4. 4

   Inspect temperature sensor connections if accessible.
