Question about 2003 Lexus Gs 300
Check engine light came on alittle over a month ago. Was diagnosed with the error code P1135. Had an experienced technition replace the bank 1 sensor 1 O2 sensor on my 2002 ES300 with an OE sensor. Check engine light soon went off & stayed off but the "Trac Off" light as well as the "VCS" lights stay on. I then went and passed emissions with both those lights on. No error codes appeared at the emission test station. Disconected the battery to re-set codes but the "Trac Off" and "VCS" light keep coming on after I drive a few yards. ANY help would greatly be appreciated as I know the dealer suggested to disconnect the battery which I did, but here I am.
Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.
Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.
