Inspection Procedure 8: The electric parking brake switch indicator lamp does not come on or flash normally.
 
 
 
 
OPERATION
  • The electric parking brake switch indicator lamp illuminates when the electric parking brake is activated.
  • The electric parking brake switch indicator lamp blinks when the overheat protection mode for electric motor or the maintenance mode is activated.
 
 
COMMENTS ON TROUBLE SYMPTOM
When the electric parking brake switch indicator lamp illuminates or blinks normally, the electric parking brake switch, the electric parking brake ECU or its associated wire(s) or connector(s) may be defective.
 
 
PROBABLE CAUSES
  • Malfunction of the electric parking brake switch (indicator lamp)
  • Malfunction of the electric parking brake ECU
  • Damaged wiring harness or connector
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the electric parking brake switch (indicator lamp).
Check the electric parking brake switch (indicator lamp) (Refer to ).
Is the check result normal?
Go to Step 2.
Replace the electric parking brake switch (Refer to ).
 
STEP 2. Measure the voltage at the electric parking brake switch connector.
(1) Disconnect the electric parking brake switch connector and measure at the wiring harness side.
(2) Measure the voltage between the terminal No.5 and body earth.
OK: Battery voltage
Is the check result normal?
Go to Step 3.
The power supply circuit may be open. Repair the wiring harness wires or connectors between the electric parking brake switch connector and the fusible link.
 
STEP 3. Measure the resistance at the electric parking brake ECU connector and the electric parking brake switch connector.
(1) Disconnect the connector and measure at the wiring harness side.
(2) Measure the resistance between the electric parking brake ECU connector PIND terminal and the electric parking brake switch connector terminal No.6.
OK: Continuity exists (2 Ω or less).
(3) Measure the resistance between the electric parking brake ECU connector PIND terminal and body earth.
OK: No continuity.
Is the check result normal?
Go to Step 4.
The signal circuit may be open or short to earth. Repair the wiring harness wires or connectors between the electric parking brake switch and the electric parking brake ECU.
 
STEP 4. Retest the system
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction).
Replace the electric parking brake ECU (Refer to ).
