Important: Before using the symptom charts, you must complete the following steps.


1. Before using the symptom charts, perform a diagnostic system check to verify the following points are true.
  1. There are no fault codes.
  2. Controllers can communicate via a serial communication line.

2. View the system operation to become familiar with the system's functions.

Visual inspection / physical control



Some symptom diagnostic procedures require a thorough visual inspection/physical check. This step is extremely important - it can lead to the solution of the problem without further checks and save valuable time. These checks include the following:
  • Inspect for aftermarket equipment that may affect the operation of the lighting system.
  • Inspect easily accessible or visible wiring harness components and connectors for obvious signs of damage or conditions that could cause this symptom.
  • If only one lamp does not work, inspect and repair the faulty connection or open in the power or ground circuit before replacing the lamp.

Faulty electrical connections or wiring can also cause intermittent faults. See Section 9A, "Checking the body wiring systems for intermittent faults and contact problems."
