The first generation Prius did not have flashable computers - that came in 2004 with the second generation. However, failure of any of them is a very rare thing. Bench testing is also impractical - they are a computer network (but not CAN) with an engine computer, battery computer, hybrid computer, body computer, brake computer, power steering... did I miss any?































In your other question you mention a hybrid code #160. Whatever it is I am sure it is not a computer problem. Weak spots in the first generation were MG2 in the transaxle and the hybrid battery - especially in the NHW10. You can do a confidence check of MG2 by draining a bit of transaxle fluid onto a paper towel. It should smell like lubricating oil; if it has a burned smell the MG2 stator has probably burned up.































The battery is harder to check. The telling indication is excessive difference between highest and lowest module voltages. Your Toyota dealer can read the data on their THHT and will know if that is the problem.
