Trouble Diagnoses — Diagnostic Procedure 17 (Cont'd)
EF & EC-117flowchartM/T model uses neutral switch (terminals a and b); A/T model uses inhibitor switch and relay (terminals 1-2, 3, 5). Separate continuity and resistance check procedures for M/T and A/T models.
Diagnostic Procedure 17 (Cont'd)
1
INSPECTION START
2
CHECK INPUT SIGNAL.
1) Turn ignition switch "ON".
2) Check continuity between terminal (44) and ground.
M/T model:
Shift lever position "Neutral" — Continuity: Yes
Shift lever position Except "Neutral" — Continuity: No
A/T model:
Shift lever position "Neutral" or "Park" — Continuity: Yes
Shift lever position Except "Neutral" or "Park" — Continuity: No
O.K.
INSPECTION END
N.G.
3
1) Turn ignition switch "OFF".
— M/T model —
2) Disconnect E.C.U. harness connector and neutral switch harness connector.
3) Check resistance between terminals (44) and (a).
— A/T model —
2) Disconnect E.C.U. harness connector and inhibitor relay.
3) Check resistance between terminals (44) and (5).
Resistance: Approximately 0Ω
N.G.
Repair or replace harness or connectors.
O.K.
4
CHECK COMPONENT.
M/T model
• Neutral switch
A/T model
• Inhibitor switch and relay
(See page EF & EC-127.)
