Why to choose ChkOBD?
ENGINES Values
(free functions included, extended values after a modest flat fixed fee)
You are a “Car Enthusiast” and there are few parameters that you would like to monitor on your engine, ..that your dash board gauges do not display !
If you feel confident by the readings of value that we are offering for free, you may want to have access of the extended values that your car would let you access (visible in gray on the list) and would become instantly available after the one time purchase of this option.
SMOG Check
Available after a one month subscription fee.
You are in a country (or the state of a country) where your car, after certain time of “Warranty” has to go though a pollution control examination.
Before going to such official test station, you would like to know if your car would pass this test. (like a “pre-test”). If it would pass, this is good info, to know, ..before going out there and paying the official test. And if our pre-test would fail, the precious info to get is the reason why it would fail. Sometime it could be very simple things like the gasoline filing cover that become defective !
VIN Analyzer
(Data available after a very modest fixed fee)
You are curious about the origin of your car, ..or about a car that you may acquire VIN Analyzer is a VIN decoder that let you have explanations like the date of manufacturing, the country of manufacturing. In the US country, VIN Analyzer is also searching information that is stored in the government database.
ERROR Analyzer
(Data available after fixed fee)
Your car does display the infamous “Check Engine Light” (CEL) on your dashboard ? Or, you have a glance on a used car that is for sale ?
In both cases it would be very good reasons to run an engine error scan. In the case of having the CEL light on, when the user manual says “go to dealer ASAP”, we strongly believe that knowing the fault (and/or the defective component) before talking to your repair shop could be a very good asset. ..Like before buying a used car, being sure that there are no pending errors on it could be an good information.
