HOW TO PROCEED WITH TROUBLESHOOTING





WARNING: How to erase memory trouble code? Memory contents are deleted with scan tool. In addition, TCM erases every memory when "DGC" terminal does not short circuit for more than 5 speeds and then it short circuit "body earth" for more than 5 speeds.

CAUTION: Make sure to implement the above operation because all the DTC remains in TCM, once they are memorized, even if a battery is removed. Negligence of this operation may lead to DTC misidentification.
