Inspection Procedure

HINT:

When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 are output accompanied by C1210/36 or C1336/39, inspect and repair the trouble areas indicated by U0073/94, U0100/65,U0123/62, U0124/95 or U0126/63 first.

1. PERFORM YAW RATE AND DECELERATION SENSOR ZERO POINT CALIBRATION 
   1. Perform the zero point calibration of the yaw rate sensor and deceleration sensor (See CALIBRATION  ).
2. RECONFIRM DTC 
   1. Clear the DTCs (See DTC CHECK/CLEAR  ).
   2. Check if the same DTCs are recorded (See DTC CHECK/CLEAR  ).

   A: Go to next step 

3. CHECK YAW RATE AND DECELERATION SENSOR INSTALLATION 
   1. Check that the yaw rate and deceleration sensor has been installed properly (See INSTALLATION  ).

      OK: 

      The sensor is tightened to the specified torque. The sensor is not tilted. 

   NG: INSTALL YAW RATE SENSOR CORRECTLY  (See INSTALLATION  )

   OK: Go to next step 

4. CHECK HARNESS AND CONNECTOR (ECU - PARK/NEUTRAL POSITION SWITCH OR PARKING BRAKE SWITCH) 
   1. NT
      1. Disconnect the skid control ECU connector.

         Tester Connection	Specified Condition
         A4-28 (PKB) - E22-1	Below 1 Ω

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

   OK: Go to next step 

5. INSPECT PARK/NEUTRAL POSITION SWITCH (FOR A/T) OR PARKING BRAKE SWITCH (FOR M/T) 
   1. Inspect the Park/Neutral Position (PNP) switch (for A/T models).
      1. Disconnect the PNP switch connector.

         Gear Selector Lever Positions	Tester Connections	Specified Conditions
         P	2 - 6, 4 - 5	Below 1 Ω
         R	1-2	Below 1 Ω
         N	2 - 9, 4 - 5	Below 1 Ω
         D	2-7	Below 1 Ω
         2	2-3	Below 1 Ω
         L	2-8	Below 1 Ω

   2. Inspect the parking brake switch (for M/T models).
      1. Disconnect the parking brake switch connector.

      2. Measure the resistance.

         Standard resistance 

         RESISTANCE SPECIFICATION
         
         

         Tester Connection	Condition	Specified Condition
         1 - Ground part	Parking brake switch ON (Switch pin released)	Below 1 Ω
         1 - Ground part	Parking brake switch OFF (Switch pin pushed in)	10 kΩ or higher

   NG: REPLACE PARK/NEUTRAL POSITION SWITCH (FOR A/T) OR PARKING BRAKE SWITCH (FOR M/T) 

   OK: Go to next step 

6. REPLACE YAW RATE AND DECELERATION SENSOR 
   1. Replace the yaw rate and deceleration sensor (See REMOVAL  ).
7. PERFORM YAW RATE AND DECELERATION SENSOR ZERO POINT CALIBRATION 
   1. Perform the zero point calibration of the yaw rate sensor and deceleration sensor (See CALIBRATION  ).
8. RECONFIRM DTC 
   1. Clear the DTCs (See DTC CHECK/CLEAR  ).
   2. Check if the same DTCs are recorded (See DTC CHECK/CLEAR  ).
