CRESSIDA Ecu Resistance Test
CAUTION:
Perform all voltage measurements with ECU harness connector installed. Use high-impedance digital voltmeter (10,000 ohm/volt minimum). Verify battery is greater than 11 volts.
CAUTION:
When measuring resistance at ECU. DO NOT
TOUCH the ECU terminals with an ohmmeter. Turn ignition off and unplug ECU harness connector. tester probe should be inserted into wiring connector from the WIRING side.
