Bulb Checks
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The CAB is not responsible for the diagnosis of any lamp failures, no explicit checks are made on the lamps at ignition turn-on other than requesting the Instrument Cluster to illuminate the amber ABS and the red Brake indicators for a few seconds. The bulb check test confirms correct CAB and bulb operation.
