Fuel Lid Opener System Operation Message Display Malfunction |
DESCRIPTION
The combination meter assembly and ECM are connected via direct line. The combination meter assembly displays fuel lid opener system operation messages according to the fuel lid signals received from the ECM.
WIRING DIAGRAM
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.
-
The following troubleshooting procedure is based on the assumption that the SFI system and fuel lid opener system are normal. Confirm that the SFI system and fuel lid opener system are not malfunctioning before performing the following procedure.

PROCEDURE
|
1. |
INSPECT COMBINATION METER ASSEMBLY (OUTPUT VOLTAGE) |
|
*a |
Front view of wire harness connector (to ECM) |
(a) Disconnect the A22 ECM connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
A22-41 (LSTM) - Body ground |
Always |
11 to 14 V |
| NG |
|
|
|
2. |
INSPECT COMBINATION METER ASSEMBLY (INPUT WAVEFORM) |
|
*a |
Component with harness connected (Combination Meter Assembly) |
(a) Check the input waveform.
(1) Connect the A22 ECM connector.
(2) Remove the combination meter assembly with the connector(s) still connected.
(3) Connect an oscilloscope to terminal K21-34 (LST1) and body ground.
(4) Operate the fuel lid opener switch.
(5) Check the signal waveform according to the condition(s) in the table below.
-
Waveform 1:
Item
Condition
Tester Connection
K21-34 (LST1) - Body ground
Tool setting
5 V/DIV., 20 ms./DIV.
Condition
"Ready to Refuel" displayed on multi-information display
-
Waveform 2:
Item
Condition
Tester Connection
K21-34 (LST1) - Body ground
Tool setting
5 V/DIV., 20 ms./DIV.
Condition
"Close Fuel Lid" displayed on multi-information display
HINT:
This waveform is output when the fuel lid opener switch is operated if the fuel lid is open and any of the following conditions are met:
- The vehicle has been driven for 1 km (0.6 mile) or more at a speed of 50 km/h (31 mph) or more.
- 30 minutes or more have elapsed since the fuel lid opener switch was operated.
OK:
All of the waveforms are output normally.
| OK |
|
REPLACE COMBINATION METER ASSEMBLY
|
| NG |
|
REPLACE ECM
|
|
3. |
CHECK HARNESS AND CONNECTOR (ECM - COMBINATION METER ASSEMBLY) |
(a) Disconnect the K21 combination meter assembly connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
A22-41 (LSTM) - K21-34 (LST1) |
Always |
Below 1 Ω |
|
A22-41 (LSTM) or K21-34 (LST1) - Body ground |
Always |
10 kΩ or higher |
| OK |
|
REPLACE COMBINATION METER ASSEMBLY
|
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
