Electronic Control Unit - Ignition: Notes

WARNING: This page is about a different car, the 1993 Volvo 940. However, it is still accessible from the selected car via links, so may be relevant.

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. Terminal identification numbers are stamped on side of ECU connector.

NOTE: Before removing ignition control unit connector, remove fuse No. 31.
