Inspection Procedure

1. Using the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to a DTC (see CHECK FOR INTERMITTENT PROBLEMS ).

   ABS / VSC:

   Item (Display)	Measurement Item/Range (Display)	Normal Condition
   SFI COM OPN	SFI communication open detection / ERROR or NORMAL	ERROR: Momentary interruption NORMAL: Normal
   STEERING OPN	Steering sensor open detection / ERROR or NORMAL	ERROR: Momentary interruption NORMAL: Normal
   YAW RATE OPN	Yaw rate sensor open detection / ERROR or NORMAL	ERROR: Momentary interruption NORMAL: Normal

   OK: 

   There are no momentary interruptions. 

   HINT:

   Perform the above inspection before removing the sensor and connector.

NG:  Go to step  3

OK: Go to next step 

1. Record the output DTCs (for ABS, VSC, Electronically Controlled Brake System and CAN communication) (see DTC CHECK / CLEAR  for ABS, VSC and Electronically Controlled Brake System, or CA-31 for CAN).

   HINT:

   If the CAN communication system DTC and the relevant sensor DTCs are output simultaneously, troubleshoot the relevant sensor DTCs (for ABS, VSC and Electronically Controlled Brake System) after the CAN communication system returns to normal.

A: REPAIR CAN COMMUNICATION SYSTEM 

1. Repair or replace the harness or connector.
2. Check for any momentary interruption between the skid control ECU and each sensor or ECM.
3. Check that there is no momentary interruption.

1. Clear the DTC (see DTC CHECK / CLEAR ).
2. Start the engine.
3. Drive the vehicle and turn the steering wheel to the right and left at a speed of 15 km/h (9 mph) or more.
4. Check that no CAN communication system DTC is output.
5. If ABS, VSC and Electronically Controlled Brake System DTCs are output, record them.

   Display (DTC Output)	Proceed To
   DTC for the CAN communication system is output	A (see DIAGNOSIS SYSTEM )
   No DTC is output (ABS, VSC and Electronically Controlled Brake System DTCs are output)	B (see DIAGNOSTIC TROUBLE CODE CHART )
   No DTC is output (No ABS, VSC and Electronically Controlled Brake System DTCs are output)	C

   HINT:

   The CAN communication system must be normal when repairing the sensor DTCs (for ABS, VSC and Electronically Controlled Brake System).
