E.C.C. TROUBLE DIAGNOSES (Models with catalyzer without E.G.R.) — Diagnostic Procedure 10 (Cont'd)
EF & EC-76flowchartModels with catalyzer without E.G.R. (GA13DS, GA14DS & GA16DS engines). Distinguishes L.H.D. vs R.H.D. harness connectors.
Diagnostic Procedure 10 (Cont'd)
1
A (from previous page)
2
CHECK POWER SUPPLY. 1) Stop engine. 2) Disconnect F.I.C.D. control solenoid valve harness connector. 3) Turn ignition switch "ON". 4) Check voltage between terminal (a) and ground. Voltage: Battery voltage
N.G.
Check the following. • Harness connectors (R11), (E14) (L.H.D. models) • 10A fuse • Harness continuity between F.I.C.D. control solenoid valve and fuse If N.G., repair harness, or connectors.
Check the following. • Harness connectors (R11), (E14) (L.H.D. models) • 10A fuse • Harness continuity between F.I.C.D. control solenoid valve and fuse If N.G., repair harness, or connectors.

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 (1) and terminal (b). Continuity should exist.
N.G.
Check the following. • Harness connectors (R11), (E14) (R.H.D. models) • 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 (R11), (E14) (R.H.D. models) • Harness continuity between E.C.U. and F.I.C.D. control solenoid valve If N.G., repair harness, or connectors.
O.K.

CHECK INPUT SIGNAL CIRCUIT. 1) Disconnect air conditioner relay. 2) Check harness continuity between E.C.U. terminal (19) and terminal (e). Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
5
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.
