Trouble Diagnosis with CONSULT-IINHS00097
DIAGNOSTIC PROCEDURE 2
Refer to GI-38, "CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [CURRENT]”.
2. Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]” even
though malfunction is detected in “SRS Operation Check”,
check the battery voltage. If the battery voltage is less than 9 V,
charge or replace the battery. Then go to SRS-27, "
DIAGNOS-
TIC PROCEDURE 3" . If the battery voltage is OK, go to SRS-
29, "DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM
