2009 Nissan altima hybrid, came in with no crank no start. found cluster would not turn on until key is inserted into key slot. has code for P0AC4 hybrid powertrain stored in ECM, found code also for steering lock control module stored. at this time saw security light (key) indicator on. was told to install steering lock control module due to common failure. still not operating. At this time no flow chart found for ecm code. checked all fuses and verified are ok. checked main battery fuse was ok No communication is found with ABS or Transmission module. looking for direction to go towards for issue.
