INSPECTION START
Start engine.
Is engine running?
Yes

No
CHECK POWER SUPPLY-I.
1. Disconnect ECM harness
connector.
2. Turn ignition switch to
“ON” position.
3. Check voltage between
ECM connector terminal
507
and ground
Voltage: Battery voltage
If NG, check the following:
●
10A fuse
●
Harness connectors
M52
,
F103
●
Harness for open or
short-circuit between
ECM and ignition switch.
If NG, replace 10A fuse or
repair harness or connec-
tors.
OK
1. Stop engine.
2. Disconnect ECM harness connector.
3. Turn ignition switch to “ON” position.

CHECK POWER SUPPLY-II.
1. Short between ECM connector terminal
325
and engine ground with a jump
wire.
2. Check voltage between ECM terminals
