Inspection Procedure
HINT:
The whole light control rheostat should be replaced if the ODO/TRIP switch has a malfunction because this part is not identically supplied.
- READ VALUE OF TECHSTREAM (ODO/TRIP CHANGE SWITCH)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to the ON position.
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Combination Meter / Data List.
- Check the values by referring to the values in the table below.
Combination Meter:
MEASUREMENT ITEM/RANGE CHARTTester Display Measurement Item/Range Normal Condition Diagnostic Note ODO/TRIP Change Switch ODO/TRIP switch is ON/OFF ON: Switch is pushed
OFF: Switch is not pushed- OK: Switch condition (ON/OFF) can be switched by actual operation.
NG: Go to step 2
OK: REPLACE COMBINATION METER ASSEMBLY
- INSPECT ODO/TRIP SWITCH
- Remove the light ODO/TRIP switch with connector still connected.
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
STANDARD RESISTANCETester Connection Condition Specified Condition R6-1 (E) - R6-7 (RV) ODO/TRIP switch OFF → ON 10 kΩ or higher → Below 1 Ω
NG: REPLACE LIGHT CONTROL RHEOSTAT
OK: Go to next step.
- CHECK HARNESS AND CONNECTOR (BETWEEN COMBINATION METER AND ODO/TRIP SWITCH)
- Disconnect the C9 and R6 connectors.
- Measure the resistance according to the value (s) in the table below.
Standard Resistance
STANDARD RESISTANCETester Connection Condition Specified Condition C9-13 (RE) - R6-1 (E) Always Below 1 Ω C9-17 (ODO/TRIP SW) - R6-4 (RSET) Always Below 1 Ω
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: REPLACE COMBINATION METER ASSEMBLY
