Electronic Control Unit (Fuel): Notes
CAUTION:
For the following tests requiring the ignition or fuel Electronic Control Unit (ECU) to be disconnected, ensure ignition switch is in the "OFF" position before disconnecting or connecting ECU connector. Damage to ECU can result.
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.
