DTC P0605 ECMPFP:23710
Component DescriptionEBS00K97
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.
On Board Diagnosis LogicEBS00K98
This self-diagnosis has one or two trip detection logic.
FAIL-SAFE MODE
ECM enters fail-safe mode when malfunction A is detected.
DTC Confirmation ProcedureEBS00K99
Perform “PROCEDURE FOR MALFUNCTION A” first. If the DTC cannot be confirmed, perform “PRO-
CEDURE FOR MALFUNCTION B”. If there is no malfunction on “PROCEDURE FOR MALFUNCTION B”,
perform “PROCEDURE FOR MALFUNCTION C”.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
PROCEDURE FOR MALFUNCTION A
With CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. If 1st DTC is detected, go to EC-266, "
Diagnostic Procedure" .
With GST
Follow the procedure “With CONSULT-II” above.
