When the Remote Function Actuator (RFA) module enters a key programming state, it activates the backup transceiver to read the key in the backup slot. If a valid Intelligent Access (IA) key is used and there are no concerns with the Passive Anti-Theft System (PATS) the key is programmed into the RFA module memory.
- DTC B10D7:05 (PATS Key: System Programming Failure) - a continuous memory DTC that sets when an IA key is unsuccessfully programmed into the RFA module.
This pinpoint test is intended to diagnose the following:
- IA key
- Backup transceiver
