INSPECTION START
2
[A] CHECK INPUT SIGNAL CIRCUIT. 1) Disconnect E.C.U. harness connector and detonation sensor harness connector. 2) Check harness continuity between terminal (b) and E.C.U. terminal (27). Continuity should exist.
N.G.
Check the following. - Harness connectors F23, E209 (B13 L.H.D. models) - Harness connectors F5, E223 (N14 L.H.D. models) - Harness connectors F11, E215 (R.H.D. models) - Harness continuity between E.C.U. and detonation sensor. If N.G., repair harness or connectors.
Check the following. - Harness connectors F23, E209 (B13 L.H.D. models) - Harness connectors F5, E223 (N14 L.H.D. models) - Harness connectors F11, E215 (R.H.D. models) - Harness continuity between E.C.U. and detonation sensor. If N.G., repair harness or connectors.
