(Hybrid) Vehicle Stalls When Shifted Out Of Park - keywords 2 2-mode 2ML70 6.0L engine hybrid hp2 M99 mode stall start stop two two-mode

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may state that the vehicle stalls after shifting out of park quickly after a key crank.

This is a normal condition and no parts should be replaced to try and resolve this concern. The 2-Mode Hybrid requires a certain amount of engine run time (1-2 seconds) from initial key crank before moving the gear shift indicator out of park. Some customers may experience a stall condition that results from an immediate shift out of park prior to the engine reaching full operating RPM. If such a condition occurs, the transmission selector should be placed back in Park and the key should be cycled off. The engine can then be restarted, and after waiting approximately 1-2 seconds, a shift can be made without further engine operation interruption.

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.
