Quick Answer
Choose the Innova 5210 if battery/charging-system testing, oil-light reset support, OBD live data, and the lower current price matter more than SRS access. Choose the Innova 5310 if verified SRS diagnostics are important and you prefer Innova’s explicit no-subscription/no-update-fee policy. Neither model is verified as all-system or bidirectional.

Why Choose the 5310?
The 5310 adds verified SRS diagnostics to engine and ABS coverage. Innova also states no subscriptions and no update fees. Newer FCA vehicles that require AutoAuth can limit some write/reset operations, so vehicle-specific compatibility matters.

Important Limitations
- Neither model should be treated as an all-system or bidirectional scanner.
- Innova says the 5310 does not reprogram vehicle computers or key fobs.
- Newer FCA AutoAuth requirements can limit some 5310 write/reset operations.
- Vehicle-specific feature coverage should be checked before buying either model.
Bottom Line
5210 = lower-cost engine/ABS tool with strong OBD data and battery/charging features. 5310 = engine/ABS/SRS diagnostics with an explicit no-subscription/no-update-fee ownership model. The decisive question is whether you need SRS access or battery/charging functionality more.
