FL-124 EFI SYSTEM — Electronic Control System 7M-GE [DIAGRAM showing ECU Wiring with IDL and E2 connections to Ohmmeter] 7M-GTE [DIAGRAM showing ECU Wiring with IDL and E2 connections to Ohmmeter] F04221 F01251 3. INSPECT RESISTANCE OF ECU NOTICE: • Do not touch the ECU terminals. • The tester probe should be inserted into the wiring connector from the wiring side. Check the resistance between each terminal of the wiring connectors. • Disconnect the connectors from the ECU. • Measure the resistance at each terminal.
