Tests AD: DTC U0155 Lost Communication With Instrument Panel Cluster (IC) Control Module

PINPOINT TEST AD: DTC U0155 LOST COMMUNICATION WITH INSTRUMENT PANEL CLUSTER (IC) CONTROL MODULE

AD1:

AD2-AD4:

Normal Operation
The smart junction box (SJB) communicates the headlamps on status to the instrument cluster over the medium speed controller area network (MS-CAN). The instrument cluster acts as a gateway module and relays the information through the high speed controller area network (HS-CAN). The adaptive front lighting module receives headlamps on status information from the instrument cluster gateway. If the adaptive front lighting module does not receive communication from the instrument cluster, DTC U0100 is set.

This pinpoint test is intended to diagnose the following:
- Adaptive front lighting module
- Instrument cluster
