CUSTOMER CONCERN The vehicle has a no-crank, no-start condition with a Service Hybrid System message and DTC P0BBD after an earlier stall. CAUSE The BECM reported insufficient drive-motor battery voltage, and the confirmed repair identified the high-voltage battery assembly as failed. CORRECTION Remove and replace the drive-motor high-voltage battery assembly, clear DTC P0BBD, and verify starting and hybrid-system operation.

CUSTOMER CONCERN The vehicle will not crank, the instrument cluster remains dark, and DTCs U0155 and P1260 are stored. CAUSE Cluster power, ground, and high-speed CAN circuits were intact, confirming an internal instrument-cluster failure that disabled the PATS start authorization. CORRECTION Remove and replace the instrument cluster, clear U0155 and P1260, and verify cluster communication and starting operation.

CUSTOMER CONCERN The engine will not crank and DTC U1888 is stored. CAUSE Corrosion inside the underhood auxiliary fuse block caused a low-voltage feed at terminal J1, preventing BECM and serial-data-gateway communication. CORRECTION Remove and replace the auxiliary fuse block, clear DTC U1888, and verify module communication and starting operation.

CUSTOMER CONCERN The engine will not crank after engine replacement and DTCs P1B06, P1B05, and P1AE2 are stored. CAUSE Inspection confirmed the high-voltage battery disconnect lever was broken during the disconnect procedure, leaving the interlock circuit open. CORRECTION Remove and replace the high-voltage battery disconnect lever, fully seat the interlock components, clear the DTCs, and verify the engine cranks.
