Inspection Procedure

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

   DATA LIST: ABS / VSC / TRAC 

   DATA LIST
   
   

   Item	Measurement Item / Range (Display)	Normal Condition
   EFI Open	EFI communication open detection / OPN DET or NORMAL	OPN DET: Momentary interruption NORMAL: Normal
   Steering Open	STEERING SEN Steering sensor open detection / OPN DET or NORMAL	OPN DET: Momentary interruption NORMAL: Normal
   Yaw Rate Open	Yaw rate sensor open detection / OPN DET or NORMAL	OPN DET: 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, and CAN communication).

   HINT:

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

NEXT : REPAIR CAN COMMUNICATION SYSTEM 

1. Repair or replace the harness and connector.
2. Check for any momentary interruption between the skid control ECU and each sensor or ECM (See CHECK FOR INTERMITTENT PROBLEMS  ).
3. Check that there is no momentary interruption.

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

   Result	Proceed to
   DTC output for the CAN communication system	A
   No DTC is output (ABS and VSC DTCs are output)	B
   No DTC is output (No ABS and VSC DTCs are output)	C

   HINT:

   • The CAN communication system must be normal when repairing each sensor DTC (for ABS and VSC).
   • These DTCs may be restored due to a malfunction in the connector terminal connection, etc.
