Trouble Diagnosis with CONSULT

1. Connect CONSULT.
2.  DTC is displayed on SELF-DIAG RESULTS.

NOTE: If a malfunction is not detected on SELF-DIAG RESULTS [CURRENT], but a malfunction is detected during

SRS Operation Check, the following cases may exist:

• SELF-DIAG [PAST] memory might not be erased. Refer to SRC-16, "On Board Diagnosis Function".
•  SRS system malfunctions intermittently. Refer to SRC-45, "Inspection Procedure".

DIAGNOSIS MODE

1.  Connect CONSULT.
2.  Confirm that zero point reset of OCS is complete.
3.  If no DTCs are detected on “SELF-DIAG RESULTS [CURRENT]”, repair of SRS is completed. Go to step 4.

   If any DTCs are detected on “SELF-DIAG RESULTS [CURRENT]”, the malfunction has not been repaired completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to SRC- 16, "On Board Diagnosis Function".

4.  Touch “ERASE”.

   NOTE: Touching “ERASE” will clear the SRS memory of the malfunction (“SELF-DIAG [PAST]”). If “SELFDIAG [PAST]” is not erased, User Mode may show the previous system malfunction even if the malfunction has been repaired completely.

5.  Check that no malfunction is detected in “SELF-DIAG [PAST]”.
6.  Exit Diagnosis Mode and disconnect the CONSULT.
7.  Perform SRS Operation Check. Refer to SRC-16, "On Board Diagnosis Function".

SRS HISTORY CHECK
