Pinout Values and Diagnostic Parameters
ECU PINOUT VALUESNOTE:
1. The EFI circuit can be checked by measuring the voltage at the wiring connectors of the ECU.
2. Perform all voltage measurements with the connectors connected.
3. Verify that the battery voltage is 11 V or above when the ignition switch is ON.
VOLTAGE MEASUREMENT
Using a voltmeter with high-impedance (10 kohm/V minimum), measure the voltage at each terminal of the wiring connector.
NOTE: If there is any problem, see TROUBLESHOOTING EFI ELECTRONIC CIRCUIT WITH VOLT/OHMMETER.
Connector View/Terminal Identification
Standard Values
RESISTANCE MEASUREMENT
Check the resistance between each terminal of the wiring connector.
CAUTION:
1. Do not touch the ECU terminals.
2. The tester probe should be inserted into the wiring connector from the wiring side.
