- No response/not equipped for PATS module, GO to Pinpoint Test A. Test A: No Communication With the Passive Anti-Theft System (PATS) Module
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the PATS module.
