NHTSA's summary
This Preliminary Information communication provides information to the technician the steps to diagnose and repair vehicles that have Check Engine Light illuminated with an "Engine Unavailable" and "Reduced Propulsion" messages on the Driver Information Center. Technician may find Diagnostic Trouble Codes a P0AB9 and P0AC4. Technician should not clear any Diagnostic Trouble Codes and ensure Global Diagnostic System 2 is up to date. Technician will need to use Global Diagnostic System 2 and check all modules for Diagnostic Trouble Codes. Now use Global Diagnostic System 2 to create freeze frame data from Hybrid Powertrain Control Module and the Engine Control Module and save a report. Technician will need to verify that the vehicle had not been run very low or out of fuel. Also verify the customer did not press the Power Button causing the vehicle to turn off while driving. Verify that the Internal Combustion Engine runs properly and no other engine related or communication related Diagnostic Trouble Codes are present. Technician should inquire if the remote star was used on the last two drive cycles before the Diagnostic Trouble Code set. Technician should update the Engine Control Module if so. Technician should inspect the ground locations G106 (engine block) and G113 (drive unit case) have been cleaned and are secure making sure the ground eyelets do not spin. Technician should also check for past service history for prior mechanical engine or wiring harness repairs. Inspect the cam timing connector and repair any damage.
