DTC B13A6:11 [FORWARD SENSING CAMERA (FSC)]

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. (See DTC INSPECTION [INSTRUMENT CLUSTER].) • 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. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].) • 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. (See FOW/LDWS SWITCH INSPECTION.) • 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. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].) • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • 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. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • 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. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].) • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • 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. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • Is the same DTC displayed? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the forward sensing camera (FSC). (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.) 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.
