Diagnostic Procedure 33 (Cont'd)
EF & EC-323flowchartStep B/C measurement terminals differ between L.H.D. and R.H.D. models; L.H.D. uses connectors F24/M56, R.H.D. uses connectors F33/M37.
Diagnostic Procedure 33 (Cont'd)
1
INSPECTION START
2
CHECK CONTROL FUNCTION. 1) Turn ignition switch "ON". 2) Listen to fuel pump operating sound. Fuel pump should operate for 5 seconds after ignition switch is turned "ON".
N.G.
Check fuel pump control circuit. (See page EF & EC-318.)
O.K.
3
CHECK POWER SUPPLY. 1) Turn ignition switch "OFF". 2) Disconnect air regulator harness connector. 3) Turn ignition switch "ON". 4) Check voltage between terminal (a) and ground (L.H.D. models), terminal (b) and ground (R.H.D. models). Battery voltage should exist for 5 seconds after ignition switch is turned "ON".
N.G.
Check the following. - Harness connectors F24, M56 (L.H.D. models) - Harness connectors F33, M37 (R.H.D. models) - Harness connectors M11, E104 - Harness continuity between air regulator and fuel pump relay. If N.G., repair harness or connectors.

4
CHECK GROUND CIRCUIT. 1) Turn ignition switch "OFF". 2) Check harness continuity between terminal (b) and body ground (L.H.D. models), terminal (a) and ground (R.H.D. models). Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
5
CHECK COMPONENT (Air regulator). Refer to "Electrical Components Inspection". (See page EF & EC-350.)
N.G.
Replace air regulator.
