OK >> GO TO EC-660, "IGNITION SIGNAL" .
NG >> Replace ECM relay.
10.CHECK ECM POWER SUPPLY CIRCUIT-III
1. Stop engine and wait at least 10 seconds.
2. Turn ignition switch “ON” and then “OFF”.
3. Check voltage between ECM terminals 119, 120 and ground
with CONSULT-II or tester.
OK or NG
OK >> GO TO 14.
NG (Battery voltage does not exist.)>>GO TO 11.
NG (Battery voltage exists for more than a few seconds.)>>GO TO 12. Continuity should exist.
Voltage: After turning ignition switch “OFF”, battery
voltage will exist for a few seconds, then
drop approximately 0V.
