Question

Can anyone tell me how to resolve code B1650 on the 2008 Toyota Highlander V6. There is a message to check the SRS airbag system

Answer 1

Dirty oil is the most common cause for this problem, if you have not replaced the oil in the last 4k miles replace the oil and oil filter. If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.

SRS is not related to this, you will have to use a OBD-II reader that reads air bag to get the code.
