E.C.C. TROUBLE DIAGNOSES (Models with catalyzer without E.G.R.) — Diagnostic Procedure 13 (Cont'd)
EF & EC-84flowchartL.H.D. models use harness connectors E5, E20; R.H.D. models use harness connectors D54, E20. Applies to GA13DS, GA14DS & GA16DS models with catalyzer without E.G.R.
Diagnostic Procedure 13 (Cont'd) — Neutral switch
1
Neutral switch — INSPECTION START
2
CHECK OVERALL FUNCTION. 1) Set shift lever to the neutral position. 2) Make sure that clutch pedal is fully released. 3) Disconnect E.C.U. harness connector. 4) Check harness continuity between E.C.U. terminal (4) and body ground. Continuity should exist.
O.K.
INSPECTION END
N.G.
3
CHECK GROUND CIRCUIT. 1) Disconnect neutral 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 (a). Continuity should exist.
N.G.
Check the following. - Harness connectors (E5), (E20) (L.H.D. models) - Harness connectors (D54), (E20) (R.H.D. models) - Harness continuity between E.C.U. and neutral switch. If N.G., repair harness or connectors.

CHECK COMPONENT (Neutral switch). Refer to "Electrical Components Inspection". (See page EF & EC-147.)
N.G.
Replace neutral switch.
O.K.
6
Check E.C.U. pin terminals for damage or the connection of E.C.U. harness connector.
