DTC Check




1. Using SST, create a short-circuit between terminals TC and CG of the DLC3.

SST 09843-18040

2. Turn the ignition switch on (IG).




3. Read and record DTCs from the door warning light on the combination meter. As examples, refer to the chart for the blinking patterns of the normal system code and diagnostic trouble code 42.

HINT:
- If the door warning light does not conform to DTC blinking patterns, or to the normal system code blinking pattern, inspect the multiplex communication system.
- The door warning light circuit uses BEAN for communication. If there are any malfunctions in the circuit, check for DTCs in the multiplex communication system.
