Cooling fan 1 speed control output overload.
â–¶ How to fix
Check FAN for blockage Change FAN
What you'll see
If fan is not working the battery temperature will rise and eventually the battery temperature will be a limitation in the powermanagement in BMU. This can lead to less energy cycling of propulsion battery.
System reaction
No direct system reactions. Yellow hybrid malfunction lamp
Diagnostic depth
Detection
2. FAN has a diagnose pin that communicates fault modes from FAN to BMU. The FAN has following failure modes: 2.a: FAN blocked, FAN not rotating 2.b: FAN driver overheated 2.c: Too high current 2.d: Internal drive failure
Possible cause
Internal error in FAN
