PINPOINT TEST AD: DTC U0155 - LOST COMMUNICATION WITH INSTRUMENT PANEL CLUSTER (IC) CONTROL MODULENormal Operation
The smart junction box (SJB) communicates the headlamps on status to the instrument cluster (IC) over the medium speed controller area network (MS-CAN). The IC acts as a gateway module and relays the information through the high speed controller area network (HS-CAN). The headlamp control module (HCM) receives headlamps on status information from the IC gateway. If the HCM does not receive communication from the IC, DTC U0155 is set.
This pinpoint test is intended to diagnose the following:
- HCM
