Code No. C1614: Parking Brake Switch System (Stuck On)
 
 
caution
  • If there is any problem in the CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
  • Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
 
 
OPERATION
The AWC-ECU receives actuation signals of the parking brake from the combination meter.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when driving for a long time with the parking brake operating.
 
 
PROBABLE CAUSES
  • Malfunction of the parking brake switch <Vehicles without electric parking brake>
  • Damaged harness wires and connectors
  • Malfunction of the combination meter
  • Malfunction of the AWC-ECU
  • Malfunction of the electric parking brake ECU <Vehicles with electric parking brake>
  • The vehicle was driven with the parking brake applied.

 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to perform the CAN bus diagnosis.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE data list.
Check the following data list (Refer to ).
  • Item No.46: Parking brake
Is the check result normal?
Go to Step 7.
NO <Vehicles without electric parking brake> : Go to Step 3.
NO <Vehicles with electric parking brake> : Go to Step 6.
 
STEP 3. Check the parking brake switch.
Check the parking brake switch (Refer to GROUP 36 - On-vehicle Service ).
Is the check result normal?
Go to Step 4.
Replace the parking brake switch (Refer to GROUP 36 - Parking Brake Lever ).
 
STEP 4. Measure the resistance at the parking brake switch connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between parking brake switch connector terminal No.1 and body earth.
OK: No continuity
Is the check result normal?
Go to Step 7.
Go to Step 5.
 
STEP 5. Check the wiring harness between combination meter connector BRK terminal and parking brake switch connector terminal No.1.
Check the power supply line for short circuit.
Is the check result normal?
Replace the combination meter (Refer to GROUP 54A - Combination Meter ).
Repair the defective connector or the wiring harness.
 
STEP 6. M.U.T.-IIISE diagnosis code.
Check the electric parking brake ECU diagnosis code (Refer to GROUP 36 - Troubleshooting ).
Is the diagnosis code set?
Perform the relevant troubleshooting.
Go to Step 7.
 
STEP 7. Check whether the diagnosis code is set again.
Is diagnosis code No.C1614 set?
Replace the AWC-ECU (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
