Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure
EBS00QZD
1.
CHECK ECM POWER SUPPLY
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Check voltage between ECM terminal 121 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 3.
NG
>> GO TO 2.
2.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors E106, M11 (LHD models)
●
Harness connectors E145, M80 (RHD models)
●
10A fuse
●
Harness for open or short between ECM and battery
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.
CHECK INTERMITTENT INCIDENT
Refer to
EC-644, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"
.
OK or NG
OK
>> GO TO 4.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
