Pinpoint Test D : Unable To Program Keys: Notes
Refer to Passive Anti-Theft System , for schematic and connector information.
Normal Operation and Fault Conditions
Refer to Anti-Theft .
The RFA module uses the backup transceiver to operate the PATS in the event of a failure of any passive start antenna, a discharged battery in the passive key, or a communication concern with the TPM module. The backup transceiver is also used for passive key programming.
The backup transceiver receives voltage and ground directly from the RFA module. The RFA module controls the backup transceiver through the dedicated clock and data circuits.
RFA Module DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10D9:11 | PATS Transponder: Circuit Short to Ground | Sets when the RFA module detects a short to ground from the transceiver voltage supply circuit. |
| B10D9:12 | PATS Transponder: Circuit Short to Battery | Sets when the RFA module detects a short to voltage from the transceiver voltage supply circuit. |
| B10D9:31 | PATS Transponder: No Signal | Sets when the RFA module does not receive a signal from the backup transceiver. |
| B10D9:87 | PATS Transponder: Missing Message | Sets when the RFA module cannot initialize the backup transceiver. |
