When you replace a used Kessy PQ35, module ( access and start authorization ), we will be given an error code “No basic setting”.
And you won’t recognize the keys just by bringing them closer to the antenna.
Jetta a6 of very common presence among others.
A KESSY PQ35 fault “No Basic Setting” usually indicates that the electronic control unit (ECU) of the keyless entry and start system (KESSY) needs to be re-learned. This occurs when the KESSY module is used as a used part and has been detected as installed in a new vehicle. The fault code “65826 – no basic adaption (B2010 00 009)” is often associated with this issue.
To solve it you can use odis online and parameterize it or Launch X431/Thinkcar in the function of parameterizing online.
But also Xhorse VAG iscancar MM-007 scanner gives you the option to parametize it.
