E. CHECK OUTPUT SIGNAL CIRCUIT. 1) Turn ignition switch "OFF". 2) Disconnect E.C.U. harness connector. 3) Check harness continuity between E.C.U. terminal 100 and terminal 5. Continuity should exist.
N.G.
Check the following. - Harness connectors F32, M37 - Harness connectors M11, E184 - Harness continuity between E.C.U. and F.I.C.D. control solenoid valve. If N.G., repair harness or connectors.
Check the following. - Harness connectors F32, M37 - Harness connectors M11, E184 - Harness continuity between E.C.U. and F.I.C.D. control solenoid valve. If N.G., repair harness or connectors.

F. CHECK INPUT SIGNAL CIRCUIT. 1) Disconnect air conditioner relay. 2) Check harness continuity between E.C.U. terminal 5 and terminal 6. Continuity should exist.
N.G.
Check the following. - Harness connectors F54, M36 - Harness connectors M11, E184 - Diode M12 (N14 models with daytime light system) - Diode M8 (N14 models without daytime light system) - Diode M14 (B13 models) - Harness continuity between E.C.U. and air conditioner relay. If N.G., repair harness or connectors.

CHECK COMPONENT (F.I.C.D. control solenoid valve). Refer to "Electrical Components Inspection". (See page EF & EC-149.)
N.G.
Replace F.I.C.D. control solenoid valve.
O.K.
Check E.C.U. pin terminals for damage or the connection of E.C.U. harness connector.
