When an Integrated Keyhead Transmitter (IKT) key is programmed, the Remote Keyless Entry (RKE) Transmitter Identification Code (TIC) data from the key is received by the Instrument Panel Cluster (IPC). The IPC then sends the TIC data to the Smart Junction Box (SJB) over the Medium Speed Controller Area Network (MS-CAN). The SJB stores the TIC data in memory and sends an acknowledgement back to the IPC that the TIC data was successfully programmed.
- DTC B109E:51 (Remote Keyless Entry: Not Programmed) - a continuous DTC that sets when the IPC sends the RKE TIC data to the SJB over the MS-CAN, and it does not receive a response from the SJB that the TIC data has been stored.
This pinpoint test is intended to diagnose the following:
- IKT programming
- MS-CAN
- SJB
