54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > ULTRASONIC MISACCELERATION MITIGATION SYSTEM/CORNER SENSOR SYSTEM > DIAGNOSIS CODE PROCEDURES > CODE No. C2225 Corner sensor switch
Code No. C2225 Corner sensor switch
 
 
 
 
OPERATION
The clearance warning control unit sets diagnosis code No. C2225 when it receives sonar switch ON-signal for at least one minute, or when it detects any open circuit or short to earth in the sonar switch indicator circuit while the sonar switch indicator is deactivated.
 
 
TROUBLE JUDGEMENT
Any of the conditions below is satisfied:
  • The sonar switch signal remains ON for at least one minute.
  • The system detects a malfunction for at least three seconds when the sonar switch indicator is deactivated.
 
 
PROBABLE CAUSES
  • Malfunction of sonar switch
  • Malfunction of clearance warning control unit
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list.
Check the input signal (Refer to ).
  • Operate the sonar switch.
 
Item No.Item nameNormal condition
16Corner sensor SW indicatorNormal
77Corner sensor SW input signalWhen the switch is operated: ON
When the switch is not operated: OFF
OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
NO (Normal condition is not displayed for item No. 77) : Go to Step 2.
N.O (Normal condition is not displayed for item No. 16) : Go to Step 5.
 
STEP 2. Check the sonar switch.
Refer to .
Is the check result normal?
Go to Step 3.
Replace the sonar switch (Refer to ).
 
STEP 3. Check of short to earth circuit in CSW line between the sonar switch connector and clearance warning control unit connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. M.U.T.-IIISE data list.
Check the input signal (Refer to ).
  • Operate the sonar switch.
 
Item No.Item nameNormal condition

When the switch is not operated: OFF
OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Replace the clearance warning control unit (Refer to ).
 
STEP 5. Voltage measurement at sonar switch connector (IG terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check the voltage between the sonar switch connector (IG terminal) and body earth.
OK: System voltage
Is the check result normal?
Go to Step 7.
Go to Step 6.
 
STEP 6. Check of short to earth, and open circuit in IG line between the ETACS-ECU connector and sonar switch connector.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the connector(s) or wiring harness.
 
STEP 7. Check the sonar switch indicator.
Refer to .
Is the check result normal?
Go to Step 8.
Replace the sonar switch (Refer to ).
 
STEP 8. Check of short to earth, and open circuit in CIND line between the sonar switch connector and clearance warning control unit connector.
Is the check result normal?
Go to Step 9.
Repair the connector(s) or wiring harness.
 
STEP 9. M.U.T.-IIISE data list.
Check the input signal (Refer to ).
