INSPECTION PROCEDURE
NOTICE:
- Turn the ignition switch off before measuring the resistance of the main wire and the branch wire.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder buzzer are not in operation.
- Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
HINT: Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (COMBINATION METER - BATTERY AND BODY GROUND)
(a) Disconnect the E19 combination meter assembly (combination meter ECU) connector.




(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE COMBINATION METER ASSEMBLY (COMBINATION METER ECU)
