Tool Q&A: Should you get involved with reflashing?

Should you get involved with reflashing? Here's how to avoid nasty pitfalls.

A few free resources exist online. DrewTech’s website ( and the “OTC Tool Guy” YouTube channel (See Fig. 6) are very good and cover car-line specific reflashing. OTC Tool Guy’s videos, for example, in about six minutes cover exactly how you register on an OEM website and subsequently carry on your reflash. They have a lot of essential, real-world tips. In their video on reflashing Nissans, they warn you that after a successful reflash, the software uses the word “failure,” and cautions the technician not to be afraid. That tip comes in handy when you reflash your first Nissan so you don’t freak out and think you fried the module.
