Combination Meter Diagnosis

Combination meter controls operation of each meter, warning light and indicator light using information sent from each controller through CAN communication.

For this reason, it is necessary to diagnose trouble according to following inspection procedure when operation of combination meter is found faulty.

1. Check combination meter power and ground circuit.
2. Using SUZUKI scan tool, check each DTC of all control modules.
   • If some DTC of some control module appears during inspection in Step  2), go to applicable DTC diag. flow.
   • If any of troubles described in table below has occurred independently even though DTC display is normal during inspection is Step  2), inspect subject place according to instructions in table below.
