id0902f5414300

Description

• Front door key cylinder switch (driver’s side) circuit malfunction

Detection Condition

• Short to ground in front door key cylinder switch (driver’s side) circuit with the front door key cylinder switch (driver’s side) off.

Possible Causes

• Front door latch and lock actuator (driver’s side) connector or terminals malfunction

• Front door key cylinder switch (driver’s side) malfunction

• BCM connector or terminals malfunction

• Short to ground in wiring harness between the following terminals:

― Front door latch and lock actuator (LH) terminal H—BCM terminal 6L (L.H.D.)

― Front door latch and lock actuator (RH) terminal F—BCM terminal 6L (R.H.D.)

• BCM malfunction

Diagnostic Procedure

Step

Inspection

Action

1

PERFORM DTC INSPECTION

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the DTC B11DA:11 present?

Yes

Go to the next step.

No

DTC troubleshooting completed.

2

INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER'S SIDE) CONNECTOR CONDITION

•  Switch the ignition to off.

•  Disconnect the negative battery cable.

•  Disconnect the front door latch and lock actuator (driver's side) connector.

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Is there any malfunction?

Yes

Repair or replace the connector or terminals, then go to Step 6.

No

Go to the next step.

3

INSPECT FRONT DOOR KEY CYLINDER SWITCH (DRIVER'S SIDE)

•  Inspect the front door key cylinder switch (driver's side).
(See FRONT DOOR KEY CYLINDER SWITCH INSPECTION.)

•  Is there any malfunction?

Yes

Replace the front door latch and lock actuator (driver's side), then go to Step 6.

(See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)

No

Go to the next step.

4

INSPECT BCM CONNECTOR CONDITION

•  Disconnect the BCM connector.

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Is there any malfunction?

Yes

Repair or replace the connector or terminals, then go to Step 6.

No

Go to the next step.

5

INSPECT FRONT DOOR KEY CYLINDER SWITCH (DRIVER'S SIDE) CIRCUIT FOR SHORT TO GROUND

•  Front door latch and lock actuator (driver's side) and BCM connectors are disconnected.

•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:

―  Front door latch and lock actuator (LH) terminal H (L.H.D.)

―  Front door latch and lock actuator (RH) terminal F (R.H.D.)

•  Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to ground, then go to the next step.

No

Go to the next step.

6

VERIFY TROUBLESHOOTING COMPLETED

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the DTC B11DA:11 present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the BCM.
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

7

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [BCM].)

No

DTC troubleshooting completed.
