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 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.
5
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  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.
No
DTC troubleshooting completed.
