Electronic Control Unit (Ignition): Notes
NOTE:
When measuring resistance and voltage at ECU connector, DO NOT probe into front of connector. Probe only through side of connector, just enough to make a good electrical contact. Pin identification numbers are stamped on side of ECU connector.
NOTE:
Before removing ignition control unit connector, remove fuse No. 1 (740 Series) or fuse No. 31 (940 Series). On 240 Series, ensure ignition is off.
