WHEN THE ON BOARD SELF-DIAGNOSIS DOES NOT START

If the on board self-diagnosis does not start, check the following items.

Assumed abnormal partInspection item
Information displayCombination meter malfunctionCheck that the self-diagnosis function of the combination meter operates. Refer to " ON BOARD DIAGNOSIS FUNCTION ".
ICC steering switch malfunctionPerform the inspection for DTC "C1A06". Refer to " DTC LOGIC ".
Harness malfunction between ICC steering switch and ECM
ECM malfunction
ADAS control unit malfunctionCheck power supply and ground circuit of ADAS control unit. Refer to " DIAGNOSIS PROCEDURE ". Perform SELF-DIAGNOSIS for "ICC/ADAS" with CONSULT, and then check the malfunctioning parts. Refer to " DTC INDEX ".

Scheme 30: HOW TO ERASE ON BOARD SELF-DIAGNOSIS
  1. Turn the ignition switch OFF.
  2. Start the engine, and then start the on board self-diagnosis.
  3. Press the CANCEL switch 5 times, and then press the DISTANCE switch 5 times under the condition that the on board self-diagnosis starts. NOTE: Complete the operation within 10 seconds after pressing the CANCEL switch first. If the operation is not completed within 10 seconds, repeat the procedure from step 1 .
  4. DTC 55 is displayed after erasing. NOTE: DTCs for existing malfunction can not be erased.
  5. Turn ignition switch OFF, and finish the diagnosis.

DTC CONFIRMATION PROCEDURE

  1. PERFORM DTC CONFIRMATION PROCEDURE Start the engine. Perform "All DTC Reading" with CONSULT. Check if the "C1A00" is detected as the current malfunction in "Self Diagnostic Result" of "ICC/ADAS". Is "C1A00" detected as the current malfunction? YES: Refer to " «DIAGNOSIS PROCEDURE»(ref-573618-S39390324802013082200000) ". NO: INSPECTION END

Diagnosis Procedure

  1. CHECK SELF-DIAGNOSIS RESULTS Check if any DTC other than "C1A00" is detected in "Self Diagnostic Result" of "ICC/ADAS". Is any DTC detected? YES: Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Refer to " «ADAS CONTROL UNIT: DTC LOGIC»(ref-573618-S08665209032013082200000) ". NO: Replace the ADAS control unit. Refer to " «REMOVAL AND INSTALLATION»(ref-573617-S32428842472013082200000) ".
