Manufacturer summary

Original wording in English

This is a TJ If a customer experiences a "Propulsion System Service Required" message in the DIM, and the DTC IEM P0CBC62 is stored, please follow the advice under "Service". There have been cases where the IEM has been replaced incorrectly for this DTC, and instead, a faulty one-way valve in the coolant system was the root cause. To determine if this coolant valve is faulty, the IEM transistor temperature parameters for phases U, V, and W can be monitored and plotted with VIDA.
