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 |
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Switch Condition | Specified Condition |
H6-38 (IG+) - Body ground | Ignition switch off | Below 1 V |
Ignition switch ON | 10.5 to 16 V |
H6-22 (B) - Body ground | Ignition switch off | 11 to 14 V |
OK |
| REPLACE COMBINATION METER ASSEMBLY |
