When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM’s transistor. Use a ground other than ECM terminals,
such as the ground.
Install the break-out box between ECM and ECM harness
connectors when measuring ECM input/output voltage.
Wiring Diagrams and Trouble DiagnosisNJEC0604When you read Wiring diagrams, refer to the following:
GI-12, “HOW TO READ WIRING DIAGRAMS”
EL-12, “POWER SUPPLY ROUTING” for power distribution circuit
When you perform trouble diagnosis, refer to the following:
GI-33, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”

TROUBLE DIAGNOSIS FOR POWER SUPPLYYD
Main Power Supply and Ground Circuit (Cont’d)
EC-73
Page 1128 of 3189
DIAGNOSTIC PROCEDURENJEC0641
1 INSPECTION START
Start engine.
Is engine running?
YesorNo
Yes GO TO 13.
No GO TO 2.
2 CHECK ECM POWER SUPPLY CIRCUIT-I
1. Turn ignition switch “ON”.
2. Check voltage between ECM terminal 507 and ground with CONSULT-II or tester.
SEF895Y
OK or NG
OK GO TO 4.
NG GO TO 3.
