Circuit Description

The body control module (BCM) uses the secondary serial data bus (circuit 1061) to poll the instrument cluster for information. DTC 13 will set if there is no instrument poll from the BCM for more than 10 seconds. In practice the trouble code is set somewhere between 10 and 20 seconds after the last instrument poll is received by the instrument cluster. The DTC is reset within 10 seconds of the arrival of an instrument poll from the BCM. The DTC is logged as a History DTC.
