Cranking Leak Solenoid: Accord

Disconnect vacuum hose at cranking leak solenoid. Connect vacuum pump. Turn ignition switch to "START" position and apply vacuum.
NOTE: Engine coolant temperature must be less than 104°F (40°C).
Vacuum should remain steady while cranking. If vacuum does not remain steady, go to step 5 . If vacuum remains steady, turn ignition off and unplug 8-wire connector at control box. Measure voltage between Blue/Red (pos.) and Black (neg.) wire terminals on main wire harness while holding ignition switch in the "START" position.
If battery voltage is present, replace solenoid valve. If battery voltage is not present, measure voltage between ground and Blue/Red wire terminal with ignition switch in "START" position.
If battery voltage is present, repair open in Black wire between control box and ground. If battery voltage is not present, check for open in Blue/Red wire between control box and control unit terminal No. 27. If wire is okay, fault is at control unit. See ELECTRONIC CONTROL UNIT (ECU) test.
If vacuum did not remain steady in step 2), start engine and warm to operating temperature (cooling fan comes on). Apply vacuum to cranking leak solenoid. If vacuum remains steady, check vacuum hose for proper connection, cracks, blockage or disconnection.
If vacuum does not remain steady, unplug 8-wire connector at control box. Measure voltage between Blue/Red (pos.) and Black (neg.) wire terminals on main wire harness. If voltage is not present, replace solenoid. If there is voltage, fault is at control unit. See ELECTRONIC CONTROL UNIT (ECU) test.
