EC-59

INSPECTION START

Start engine.
Is engine running?

Yes

E

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.

and engine ground with a jump

wire.

2. Check voltage between ECM terminals
