Quick Answer
Choose the Innova 5110 if your priority is focused Engine + ABS diagnostics at the lower current price and you do not need the 5210’s verified battery/charging test or oil-reset support. Choose the Innova 5210 if those battery/charging and oil-service extras are useful enough to justify the price premium. Neither is a full-system or bidirectional scanner.

Why Choose the Innova 5110?
The 5110 makes sense when Engine + ABS is exactly the diagnostic scope you need. Innova verifies Mode 6 and RepairSolutions2 while keeping the current price below the 5210. Its FCA AutoAuth and North American protocol caveats should still be checked for your vehicle.

Is the 5210 Upgrade Worth It?
If battery/charging checks and oil reset are useful to you, the 5210 has a clear verified reason to cost more. If you only need Engine + ABS diagnosis, the 5110 is the more focused value. Do not choose either model expecting SRS, full-system scanning, or active tests.
Bottom Line
5110 = lower-cost Engine + ABS focus. 5210 = Engine + ABS plus verified battery/charging testing and oil-reset support. Buy according to the extra functions you will actually use.
