Best obd2 scanner for infiniti: what to check
Four-system coverage against engine-only readers
Only the Jokovar listing states four-system coverage, naming Engine, Transmission, ABS and SRS for 44+ brands, with Infiniti in the brand list. The TopDiag and OBDMATE listings state engine codes and full OBD2 modes, with no Transmission, ABS or SRS coverage stated. For an Infiniti driver chasing a Transmission, ABS or SRS code, the Jokovar listing is the only stated match here.
Bluetooth app against handheld screen
Jokovar works through a free app on iOS and Android over Bluetooth 5.1, with no subscription and lifetime free software updates stated, but third-party apps are not supported. TopDiag and OBDMATE are handheld units with their own screens, a 2.8 inch TFT color screen on the TopDiag and a 2.4 inch color TFT screen on the OBDMATE, and neither needs a phone app. Pick the app route for phone-based reports, and the handheld route for a screen in the car with no pairing.
Battery checks
TopDiag states the widest battery coverage here: 6-mode 12V checks covering SOH, SOC, CCA, internal resistance, starter cranking and alternator charging voltage. OBDMATE states a battery voltage check before and after engine start. Jokovar states no battery check. If a weak battery is part of the garage question, the TopDiag listing is the stated match.
Smog-check readiness
Jokovar and TopDiag both state I/M readiness, and TopDiag states a smog pre-check that confirms monitors show Ready before an official smog inspection. OBDMATE states freeze frame and live data, with no I/M readiness stated. For emissions prep, the two listings that state I/M readiness are the stated matches.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Space: the Jokovar unit measures 2.05 inches x 0.94 inches x 2.52 inches, while the TopDiag unit measures 7.48 inches x 6.29 inches x 2.04 inches, so the handheld unit needs more drawer or shelf room.
- Power: TopDiag and OBDMATE plug into the OBD2 port and power on, with no batteries or phone apps needed, per their listings.
- Storage: the OBDMATE listing calls its bright yellow, compact design easy to find and store.
- Before the first job: confirm Infiniti is in the Jokovar brand list, note that third-party apps are not supported on Jokovar, and note that data coverage may vary by make, model and year.
FAQ: garage tools
Will these scanners work on an Infiniti?
Jokovar names Infiniti among its 44+ brands for 4-system coverage.

Jokovar also notes data coverage may vary by make, model and year.
Do I need a phone to use one of these scanners?

Can one scanner check the battery too?
TopDiag states 6-mode 12V battery and charging checks, and OBDMATE states a battery voltage check before and after engine start. Jokovar states no battery check.
What does I/M readiness do for a smog check?

Do the title-only picks have stated warranties?
