how can i get rid of and diagnos the engine light?
Turn ignition key ON-OFF-ON-OFF-ON, watch odometer, write down each diagnostic code displayed ('Pxxxx', with xxxx being a 4-digit number), and post here.
P1686 - CAN data bus, immobilizer module no signal P1687 - No Mechanical Instrument Cluster (MIC) BUS message
The instrument cluster module is not communicating with the main computer. That would also trip 1686 since it communicates to the main computer through the MIC.
I have no idea what might cause that other than a loose connection in the gauge cluster.
