(b) While observing the resistance value shown on the tester, reconnect the each ECU connector until the resistance becomes abnormal
(Below 54 Ohms).
(c) Replace the ECU that caused the total resistance to drop below 54 Ohms when it was reconnected.
HINT
If the resistance becomes abnormal when an ECU connector is reconnected, there may be a short in the ECU.
NEXT -- REPLACE ECU
