CAUTION / NOTICE / HINT

NOTICE:

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
Inspect the fuses of circuits related to this system before performing the following procedure.

PROCEDURE

1.	CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)

(a) Disconnect the H6 combination meter assembly connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
H6-19 (EP) - Body ground	Always	Below 1 Ω
H6-23 (ES) - Body ground	Always	Below 1 Ω

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
H6-38 (IG+) - Body ground	Ignition switch off	Below 1 V
H6-38 (IG+) - Body ground	Ignition switch ON	10.5 to 16 V
H6-22 (B) - Body ground	Ignition switch off	11 to 14 V
