Electronic Control Unit - Ignition (240, 740 & 940): 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) or fuse No. 31 (940). On 240, ensure ignition is off.
