DTC B11CB:11 [REAR VEHICLE MONITORING SYSTEM]

id0902z2886200

Description

RVM warning indicator light (RH) circuit malfunction
Detection condition
•  Rear vehicle monitoring control module (RH) detects a short to ground in the RVM warning indicator light (RH) circuit.
Fail-safe function
•  Inhibits the rear vehicle monitoring system.
Possible cause
•  RVM warning indicator light (RH) connector or terminal malfunction
•  Rear vehicle monitoring control module (RH) connector or terminal malfunction
•  Short to ground in wiring harness between the following terminals:
―  Rear vehicle monitoring control module (RH) terminal I—RVM warning indicator light (RH) terminal G
―  Rear vehicle monitoring control module (RH) terminal H—RVM warning indicator light (RH) terminal H
•  RVM warning indicator light (RH) malfunction
•  Rear vehicle monitoring control module (RH) malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT RVM WARNING INDICATOR LIGHT (RH) CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery cable.
•  Disconnect the RVM warning indicator light (RH) 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 5.
2
INSPECT REAR VEHICLE MONITORING CONTROL MODULE (RH) CONNECTOR CONDITION
•  Disconnect the rear vehicle monitoring control module (RH) 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 5.
3
INSPECT FOR SHORT TO GROUND IN RVM WARNING INDICATOR LIGHT (RH) CIRCUIT
•  Verify that the rear vehicle monitoring control module (RH) and RVM warning indicator light (RH) connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  RVM warning indicator light (RH) terminal G
―  RVM warning indicator light (RH) terminal H
•  Is there continuity?
Yes
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  Rear vehicle monitoring control module (RH) terminal I—RVM warning indicator light (RH) terminal G
•  Rear vehicle monitoring control module (RH) terminal H—RVM warning indicator light (RH) terminal H
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 a short to ground.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to ground.
Go to Step 5.
No
Go to the next step.
4
INSPECT RVM WARNING INDICATOR LIGHT (RH)
•  Inspect the RVM warning indicator light (RH).
•  Is the RVM warning indicator light (RH) normal?
Yes
Go to the next step.
No
Replace the RVM warning indicator light (RH), then go to the next step.
(See OUTER MIRROR GLASS REMOVAL.)
(See OUTER MIRROR GLASS INSTALLATION.)
5
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC for the rear vehicle monitoring control module using the M-MDS.
•  Illuminate the RVM warning indicator light (RH) using the simulation item WRN_IND_R.
•  Retrieve the rear vehicle monitoring control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the rear vehicle monitoring control module (RH).
Go to the next step.
No
Go to the next step.
6
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 [REAR VEHICLE MONITORING SYSTEM].)
No
DTC troubleshooting completed.
