What You Need to Send

• Original 23740-5Sxxx Gen2 SH72531 ECU
• Compatible replacement/donor ECU

We strongly recommend matching the replacement ECU's part number and hardware to the original whenever possible.

Not sure if your donor ECU is compatible? Send us clear pictures of the labels on both units before shipping and we can help verify compatibility.

Original ECU Not Working?

An ECU that no longer communicates or operates correctly in the vehicle may still have recoverable data. We can attempt to read the original module directly on the bench.

If the original ECU is too severely damaged to retrieve the necessary data, we will contact you before proceeding with any alternative options.
