id0902p9029600

Description

FOW/LDWS switch circuit malfunction
Detection condition
•  Forward sensing camera (FSC) detects that the FOW/LDWS switch is held pressed for 30 s or more.
Fail-safe
•  Inhibits the lane departure warning system (LDWS).
•  Inhibits the forward obstruction warning (FOW) system.
Possible cause
•  Instrument cluster DTC is stored.
•  Cluster switch connector or terminal malfunction
•  FOW/LDWS switch malfunction
•  Instrument cluster connector or terminal malfunction
•  Short to ground in wiring harness between cluster switch terminal H and instrument cluster terminal 1Q
•  Instrument cluster malfunction
•  Forward sensing camera (FSC) malfunction

Diagnostic procedure

Step

Inspection

Action
1
VERIFY INSTRUMENT CLUSTER DTCs
•  Retrieve the instrument cluster DTCs using the M-MDS.
•  Are any DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
Go to the next step.
2
INSPECT CLUSTER SWITCH CONNECTOR
•  Turn the ignition switch to the OFF position.
•  Disconnect the negative battery cable.
•  Disconnect the cluster switch connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is there any malfunction?
Yes
Repair or replace the connector, then go to Step 7.
No
Go to the next step.
3
INSPECT FOW/LDWS SWITCH
•  Inspect the FOW/LDWS switch.
•  Is there any malfunction?
Yes
Replace the cluster switch, then go to Step 7.
(See CLUSTER SWITCH REMOVAL/INSTALLATION.)
No
Go to the next step.
4
INSPECT INSTRUMENT CLUSTER CONNECTOR
•  Disconnect the instrument cluster connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is there any malfunction?
Yes
Repair or replace the connector, then go to Step 7.
No
Go to the next step.
5
INSPECT FOR SHORT TO GROUND IN FOW/LDWS SWITCH CIRCUIT
•  Verify that the cluster switch and instrument cluster connectors are disconnected.
•  Inspect for continuity between cluster switch terminal H (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness which has a short to ground, then go to Step 7.
No
Go to the next step.
6
PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS INSTRUMENT CLUSTER
•  Make sure to reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC for the forward sensing camera (FSC) using the M-MDS.
•  Turn the ignition switch to the ON position and wait for 31.5 s or more.
•  Retrieve the forward sensing camera (FSC) DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Replace the instrument cluster, then go to the next step.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No
Go to Step 8.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC for the forward sensing camera (FSC) using the M-MDS.
•  Turn the ignition switch to the ON position and wait for 31.5 s or more.
•  Retrieve the forward sensing camera (FSC) DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the forward sensing camera (FSC).
Go to the next step.
No
Go to the next step.
8
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [FORWARD SENSING CAMERA (FSC)].)
No
DTC troubleshooting completed.
