INSPECTION PROCEDURE

NOTICE:
w/ HDD Navigation System

After the power switch is turned off, the display and navigation module display (HDD navigation system) records various types of memory and settings. As a result, after tuning the power switch off, make sure to wait 60 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.

HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
