id0902e8650400

Description

Drive selection switch circuit malfunction

Detection condition
•  Instrument cluster detects an open circuit in the drive selection switch circuit for 5 s or more with the ignition switched ON (engine off or on).
Fail-safe function
Not applicable
Possible cause
•  Drive selection switch connector or terminal malfunction
•  Open circuit in wiring harness between drive selection switch terminal C and body ground
•  Instrument cluster connector or terminal malfunction
•  Open circuit in wiring harness between instrument cluster terminal 1W and drive selection switch terminal B
•  Drive selection switch malfunction
•  Instrument cluster malfunction

Diagnostic Procedure

Step

Inspection

Action

1
INSPECT DRIVE SELECTION SWITCH CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Disconnect the drive selection switch connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 6.
2
INSPECT DRIVE SELECTION SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT
•  Verify that the drive selection switch connector is disconnected.
•  Inspect for continuity between drive selection switch terminal C (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between drive selection switch terminal C and body ground.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 6.
3
INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION
•  Disconnect the instrument cluster connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 6.
4
INSPECT DRIVE SELECTION SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Verify that the drive selection switch and instrument cluster connectors are disconnected.
•  Inspect for continuity between instrument cluster terminal 1W (wiring harness-side) and drive selection switch terminal B (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between instrument cluster terminal 1W and drive selection switch terminal B.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 6.
5
INSPECT DRIVE SELECTION SWITCH
•  Inspect the drive selection switch.
•  Is the drive selection switch normal?
Yes
Go to the next step.
No
Replace the drive selection switch, then go to the next step.
6
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Connect the negative battery terminal.
•  Clear the DTC for the instrument cluster using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 5 s or more.
•  Retrieve the instrument cluster DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the instrument cluster.
Go to the next step.
No
Go to the next step.
7
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
