Normal Operation
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
When an Integrated Keyhead Transmitter (IKT) is programmed, the Remote Keyless Entry (RKE) Transmitter Identification Code (TIC) data from the key is received by the Instrument Cluster (IC). The IC 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 acknowledgment back to the IC that the TIC data was successfully programmed.
- DTC B1137 (Data Not Programmed) - a continuous DTC that sets when the IC 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
