Motor torque reduction due to high temperature in ECU
â–¶ How to fix
Step-1: Switch-Off the ECU. Step-2: Let the ECU cool-down until the motor temperature is less than threshold temperature Step-3: Power-on the ECU. Step-4: Replace the powerpack if the DTC is still active.
What you'll see
The driver detects the following: Degradation of EPS motor torque depending on the temperature characteristic values.
System reaction
Set the Yellow Lamp to "On".
Diagnostic depth
Detection
The DTC will set during the following condition: 1.System state: DriveDown, DriveUp. 2.System voltage is above 6v. 3.System voltage is below 42v.
Possible cause
1. Defective powerpack. 2.ECU temperature greater than or equal to threshold temperature (ECU Temperature >= 115°C). 3. Internal ECU error.
