PINPOINT TEST B : B10D9:11, B10D9:12, B10D9:31 Or B10D9:87: Notes
Diagnostic Overview
B10D9:11, B10D9:12, B10D9:31 Or B10D9:87
Normal Operations and Fault Conditions
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 Intelligent Access (IA) key, or a communication concern with the TPM module. The backup transceiver is also used for Intelligent Access (IA) 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.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10D9:11 | PATS Transponder: Circuit Short to Ground | A continuous memory and on-demand DTC set by the RFA module when the backup transceiver voltage supply circuit is shorted to ground. |
| B10D9:12 | PATS Transponder: Circuit Short to Battery | A continuous memory and on-demand DTC set by the RFA module when the backup transceiver voltage supply circuit is shorted to voltage. |
| B10D9:31 | PATS Transponder: No Signal | An on-demand DTC set by the RFA module when the backup transceiver signal is not received by the RFA module. |
| B10D9:87 | PATS Transponder: Missing Message | A continuous memory and on-demand DTC set by the RFA module when the backup transceiver cannot be initialized by the RFA module. |
