ATION INSPECTION
Diagnosis ProcedureINFOID:0000000009460660
Regarding Wiring Diagram information. Refer to CHG-12, "Wiring Diagram".
CAUTION:
When performing this in spection, always use a charged battery that has completed the battery inspec-
tion. (When the charging rate of the battery is lo w, the response speed of the voltage change will
become slow. This can cause an incorrect inspection.)
1.CHECK ECM (CONSULT)
Perform ECM self-diagnosis with CONSULT. Refer to EC-77, "CONSULT Function"
(QR25DE) or EC-601,
"CONSULT Function" (VQ35DE).
