B : INSPECT CAN COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

A: Go to next step 

1. Check if the skid control ECU connector is securely connected.

   OK: 

   The connector is securely connected. 

NG: CONNECT CONNECTOR TO ECU CORRECTLY 

OK: Go to next step 

1. Check the battery voltage.

   Standard voltage: 

   11 to 14 V 

NG: CHECK OR REPLACE CHARGING SYSTEM OR BATTERY  (See ON-VEHICLE INSPECTION )

OK: Go to next step 

1. Disconnect the skid control ECU connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

OK: Go to next step 

1. Reconnect the skid control ECU connector.
2. Connect a Techstream to the DLC3.
3. Perform Active Test of the combination meter using the Techstream (See DATA LIST / ACTIVE TEST ).

   OK: 

   The VSC OFF indicator light turns ON or OFF in accordance with the Techstream. 

NG: Go to step 6 

OK : REPLACE BRAKE ACTUATOR ASSEMBLY  (See REMOVAL  )

1. Turn the ignition switch to OFF.
2. Replace the combination meter (See REMOVAL ).

1. Connect the Techstream to the DLC3.
2. Perform Active Test of the combination meter using the Techstream (See DATA LIST / ACTIVE TEST ).

   OK: 

   The VSC OFF indicator light turns ON or OFF in accordance with the Techstream. 

NG: REPLACE BRAKE ACTUATOR ASSEMBLY  (See REMOVAL  )

OK : END 

1. Disconnect the VSC OFF switch connector.
2. Measure the resistance according to the value(s) in the table below.
