Diagnostic Procedure 22 (Cont'd)
1
INSPECTION START
2
A CHECK POWER SUPPLY. 1) Turn ignition switch "ON". 2) Check voltage between E.C.U. terminals 38, 47 and ground. Voltage: Battery voltage
O.K.
B CHECK GROUND CIRCUIT. 1) Turn ignition switch "OFF". 2) Disconnect E.C.U. harness connector. 3) Check harness continuity between E.C.U. terminals 6, 13, 107, 108, 116 and engine ground. Continuity should exist. If N.G., repair harness or connectors.

C CHECK HARNESS CONTINUITY BETWEEN E.C.C.S. RELAY AND E.C.U. 1) Turn ignition switch "OFF". 2) Disconnect E.C.U. harness connector. 3) Disconnect E.C.C.S. relay. 4) Check harness continuity between E.C.U. terminals 38, 47 and terminal 5. Continuity should exist.
N.G.
Repair harness or connectors.
