id0902f5340800


Description

•  Front door latch switch (passenger’s side) circuit malfunction

Detection Condition

•  Open circuit in front door latch switch (passenger’s side) circuit with the front door (passenger’s side) closed (front door latch switch (passenger’s side) on).

Possible Causes

•  Front door latch and lock actuator (passenger’s side) connector or terminals malfunction
•  Open circuit in wiring harness between the following:
―  Front door latch and lock actuator (RH) terminal D—Body ground (L.H.D.)
―  Front door latch and lock actuator (LH) terminal J—Body ground (R.H.D.)
•  Front door latch switch (passenger’s side) malfunction
•  BCM connector or terminals malfunction
•  Open circuit in wiring harness between the following terminals:
―  Front door latch and lock actuator (RH) terminal B—BCM terminal 8D (L.H.D.)
―  Front door latch and lock actuator (LH) terminal L—BCM terminal 8D (R.H.D.)
•  BCM malfunction

Diagnostic Procedure

Step

Inspection

Action
1
PERFORM DTC INSPECTION
•  Clear the DTCs using the M-MDS.
•  Perform the BCM DTC inspection using the M-MDS.
•  Is the DTC B1176:13 present?
Yes
Go to the next step.
No
DTC troubleshooting completed.
2
INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (PASSENGER’S SIDE) CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the front door latch and lock actuator (passenger'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 7.
No
Go to the next step.
3
INSPECT FRONT DOOR LATCH SWITCH (PASSENGER’S SIDE) GROUND CIRCUIT FOR OPEN CIRCUIT
•  Front door latch and lock actuator (passenger's side) connector is disconnected.
•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:
―  Front door latch and lock actuator (RH) terminal D (L.H.D.)
―  Front door latch and lock actuator (LH) terminal J (R.H.D.)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 7.
4
INSPECT FRONT DOOR LATCH SWITCH (PASSENGER’S SIDE)
•  Inspect the front door latch switch (passenger's side).
•  Is there any malfunction?
Yes
Replace the front door latch and lock actuator (passenger's side), then go to Step 7.
(See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
No
Go to the next step.
5
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 7.
No
Go to the next step.
6
INSPECT FRONT DOOR LATCH SWITCH (PASSENGER’S SIDE) POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•  Front door latch and lock actuator (passenger's side) and BCM connectors are disconnected.
•  Reconnect the negative battery cable.
•  Switch the ignition to ON.
•  Measure the voltage at the BCM terminal 8D (wiring harness-side).
•  Can the voltage be measured?
Yes
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTCs using the M-MDS.
•  Perform the BCM DTC inspection using the M-MDS.
•  Is the DTC B1176:13 present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the BCM.
Go to the next step.
No
Go to the next step.
8
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.
