The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
On rare occasions, DTCs U0111 and U1897 may be experienced shortly after the ECM is reprogrammed. These DTCs may be false DTCs that set as a result of reprogramming the ECM.
If this concern is experienced, clear the DTCs and determine if they reset. If the DTCs do not reset, no repairs should be performed because they were false DTCs that set as a result of reprogramming the ECM. If the DTCs reset after they are cleared, there is most likely an issue with the BDU (battery disconnect unit). Perform the SI diagnostics to isolate and repair the concern as necessary.
Notice: Hybrid parts are no longer on restriction through TAC. All hybrid parts can now be ordered through your parts department.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
