How To Proceed With Troubleshooting

The hand held tester can be used at steps 3, 4, 6, 7, 11, 14, and 17.

1. VEHICLE BROUGHT TO WORKSHOP 
   1. NEXT: Go to next step. 
2. CUSTOMER PROBLEM ANALYSIS (SEE  CUSTOMER PROBLEM ANALYSIS CHECK   ) 
   1. NEXT: Go to next step. 
3. CHECK DTC AND FREEZE FRAME DATA (SEE  DTC CHECK/CLEAR   AND  FREEZE FRAME DATA OF ABS   ) 
   1. NEXT: Go to next step. 
4. CLEAR DTC AND FREEZE FRAME DATA (SEE  DTC CHECK/CLEAR   ) 
   1. NEXT: Go to next step. 
5. PROBLEM SYMPTOM CONFIRMATION 
   1. NEXT: Go to next step. 
6. CHECK CAN COMMUNICATION SYSTEM (SEE  DTC CHECK/CLEAR   ) 
   1. Check for output DTCs.

   HINT:

   The ECU of this system is connected to the CAN communication system. Therefore, before starting troubleshooting, make sure to check that there is no trouble in the CAN communication system.

   1. CAN COMMUNICATION SYSTEM DTC IS OUTPUT: PROCEED TO CAN COMMUNICATION SYSTEM (SEE  HOW TO PROCEED WITH TROUBLESHOOTING  ) 
   2. NO CAN COMMUNICATION SYSTEM DTC IS OUTPUT: GO TO STEP 7 
7. CHECK MULTIPLEX COMMUNICATION SYSTEM (SEE  DTC CHECK/CLEAR  ) 
   1. Check for output DTCs.

   HINT:

   The skid control ECU sends the signals of each warning light to the gateway ECU via CAN communication, and the gateway ECU sends the signals to the combination meter via multiplex communication system (BEAN).

   1. MULTIPLEX COMMUNICATION SYSTEM DTC IS OUTPUT: PROCEED TO MULTIPLEX COMMUNICATION SYSTEM (SEE  HOW TO PROCEED WITH TROUBLESHOOTING  ) 
   2. NO MULTIPLEX COMMUNICATION SYSTEM DTC IS OUTPUT: GO TO STEP 8 
8. DTC CHECK AND CLEAR (SEE  DTC CHECK/CLEAR   ) 
   1. NEXT: Go to next step. 
9. PROBLEM SYMPTOM SIMULATION 
   1. SYMPTOM DOES NOT OCCUR: GO TO STEP 10 
   2. SYMPTOM OCCURS: GO TO STEP   11 . 
10. SYMPTOM SIMULATION (SEE  HOW TO PROCEED WITH TROUBLESHOOTING  ) 
    1. NEXT: Go to next step. 
11. DTC CHECK (OTHER THAN CAN AND MULTIPLEX COMMUNICATION SYSTEM DTC) (SEE  DTC CHECK/CLEAR   ) 
    1. NORMAL SYSTEM CODE: GO TO STEP 12 
    2. TROUBLE CODE: GO TO STEP   13 . 
12. PROBLEM SYMPTOMS TABLE (SEE  PROBLEM SYMPTOMS TABLE   ) 
    1. NEXT: GO TO STEP   14 . 
13. DTC CHART (SEE  DIAGNOSTIC TROUBLE CODE CHART   ) 
    1. NEXT: Go to next step. 
14. CIRCUIT INSPECTION (SEE  DTC C0200/31 RIGHT FRONT SPEED SENSOR, DTC C0205/32 LEFT FRONT SPEED SENSOR, DTC C1235/35 METAL STICK TO SPEED SENSOR (FR), DTC C1236/36 METAL STICK TO SPEED SENSOR (FL), DTC C1271/71 LOW OUTPUT VOLTAGE OF RIGHT FRONT SPEED SENSOR (TEST MODE DTC), DTC C1272/72 LOW OUTPUT VOLTAGE OF LEFT FRONT SPEED SENSOR (TEST MODE DTC), DTC C1275/75 ABNORMAL CHANGE IN OUTPUT VOLTAGE OF RIGHT FRONT SPEED SENSOR (TEST MODE DTC), DTC C1276/76 ABNORMAL CHANGE IN OUTPUT VOLTAGE OF LEFT FRONT SPEED SENSOR (TEST MODE DTC)   TO  TS AND CG TERMINAL CIRCUIT   ) 
    1. NEXT: Go to next step. 
15. IDENTIFICATION OF PROBLEM 
    1. NEXT: Go to next step. 
16. REPAIR OR REPLACE 
    1. NEXT: Go to next step. 
17. CONFIRMATION TEST 
    1. NEXT: END
