Diagnostic Procedure 32 - INJECTOR
1
INSPECTION START
2
A. CHECK CONTROL FUNCTION. 1) Start engine. 2) Check voltage between E.C.U. terminals 101, 110, 103, 112 and ground. Voltage: Battery voltage
O.K.
INSPECTION END
N.G.

B. CHECK POWER SUPPLY. 1) Stop engine. 2) Disconnect injector harness connector and E.C.U. harness connector. 3) Check voltage between terminal 9 and ground, and E.C.U. terminal 109 and ground. Voltage: Battery voltage
N.G.
Check the following. - Harness connectors F34, F36 (L.H.D. models) - Harness connectors M11, M36 (L.H.D. models) - Harness connectors F18, E15 (R.H.D. models) - 25A fusible link - Harness continuity between battery and injector - Harness continuity between battery and E.C.U. If N.G., repair harness or connectors.

C. CHECK OUTPUT SIGNAL CIRCUIT. 1) Check harness continuity between terminal 9 and E.C.U. terminals 101, 110, 103, 112. Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
5
CHECK COMPONENT (Injector). Refer to "Electrical Components Inspection". (See page EF & EC-635.)
N.G.
Replace injector.
O.K.
6
Check E.C.U. pin terminals for damage or the connection of E.C.U. harness connector.
