Is the check engine light also ON.
Okay good thank you.
This check engine light malfunction codes has to be checked as any malfunction with in the engine management system will automatically trip the VRC and TRC warning lights .
For example if you get just a malfunction code for your A/F sensors this will trip the other warning light ON and disable them .
So check for codes repair the system affected and then clear code test .
