channel. If the fan is faulty,
replace it.
2. Check that the ambient
temperature has not exceeded
40° C.
3. Check that there is no overload.
1. Check the inter-rack parallel
system CAN bus.
2. Rectify the disconnection or
short-circuit fault.
3. Replace the ECM.
Replace the inter-rack parallel cable.
