(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect canister solenoid valve harness connector EN24.
(c)
Disconnect ECM harness connector EN01.
(d)
Measure resistance between canister solenoid valve wiring
harness connector EN24 terminal No.2 and ECM harness
connector EN01 terminal No.37. Check whether the circuit is
open.
(e)
Measure resistance between canister solenoid valve wiring
harness connector EN24 terminal No.2 and a reliable ground.
Check whether the circuit is short to ground.
(f)
Measure voltage between canister solenoid valve wiring
harness connector EN24 terminal No.2 and a reliable ground.
Check whether the circuit is short to power supply.
