PINPOINT TEST I : The RKE Transmitter Is Inoperative: Notes
Normal Operations and Fault Conditions
The RKE feature is controlled by the TPM module and the BCM. When a button is pressed on an IKT the TIC and RKE command is received by the internal TPM module antenna. If the TPM module determines that it is a valid and programmed TIC, it sends the RKE command and TIC to the BCM over the MS-CAN. When the BCM receives the RKE command, it carries out the command by controlling the door locks or activating the horn and turn signals for the panic alarm.
The RKE transmitters and the BCM also utilize a rolling code to prevent the code from being captured by a code grabber. The system advances the counter in the RKE transmitter and the BCM every time a RKE transmitter button is pressed.
BCM DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10AB:00 | Remote Keyless Entry Synchronization: No Sub Type Information | Sets when the BCM detects the rolling counter received from a RKE transmitter is out of synchronization with the rolling counter stored in the module. |
| B1218:00 | Transmitter Identification Code: No Sub Type Information | Sets when the BCM detects an invalid TIC from an IKT. |
