E.C.C. TROUBLE DIAGNOSES (Models with catalyzer without E.G.R.) — Diagnostic Procedure 13 (Cont'd): Inhibitor switch
EF & EC-83flowchartModels with catalyzer without E.G.R. (GA13DS, GA14DS & GA16DS engines). Inhibitor switch (A/T) procedure. Distinguishes L.H.D. vs R.H.D. harness connectors.
Inhibitor switch
Diagnostic Procedure 13 (Cont'd)
1
INSPECTION START
2
CHECK OVERALL FUNCTION. 1) Shift selector lever to "P" position. 2) Disconnect E.C.U. harness connector. 3) Check harness continuity between E.C.U. terminal (4) and engine ground. Continuity should exist. 4) Shift selector lever to "N" position. 5) Check harness continuity between E.C.U. terminal (4) and engine ground. Continuity should exist.
O.K.
INSPECTION END
N.G.
3
CHECK GROUND CIRCUIT. 1) Disconnect inhibitor switch harness connector. 2) Check harness continuity between terminal (a) and engine ground. Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
4
CHECK INPUT SIGNAL CIRCUIT. 1) Check harness continuity between E.C.U. terminal (4) and terminal (b). Continuity should exist.
N.G.
Check the following. • Harness connectors (E1), (E26) (L.H.D. models) • Harness connectors (C56), (E61) (R.H.D. models) • Harness continuity between E.C.U. and inhibitor switch If N.G., repair harness or connectors.
Check the following. • Harness connectors (E1), (E26) (L.H.D. models) • Harness connectors (C56), (E61) (R.H.D. models) • Harness continuity between E.C.U. and inhibitor switch If N.G., repair harness or connectors.
O.K.
5
CHECK COMPONENT (Inhibitor switch). Refer to "Electrical Components Inspection". (See page EF & EC-143.)
N.G.
Replace inhibitor switch.
O.K.
Check E.C.U. pin terminals for damage or the connection of E.C.U. harness connector.
