INSPECTION START
2
A: CHECK OVERALL FUNCTION. 1) Jack up front wheels. 2) Disconnect E.C.U. harness connector. 3) Rotate front wheel by hand. 4) Check harness continuity between E.C.U. terminal (12) and body ground. Continuity should come and go.

INSPECTION END
N.G.
3
CHECK SPEEDOMETER FUNCTION. Make sure that speedometer functions properly.
N.G.
Check vehicle speed sensor and circuit. (Refer to EL section.)
O.K.
4
CHECK INPUT SIGNAL CIRCUIT. 1) Turn ignition switch "OFF". 2) Disconnect combination meter harness connector. 3) Check harness continuity between E.C.U. terminal (12) and terminal (l) (Models without tachometer), terminal (l) (Models with tachometer). Continuity should exist.
N.G.
Check the following. • Harness connectors (F33), (M37) • Harness continuity between E.C.U. and combination meter. If N.G., repair harness or connectors.
O.K.
Check E.C.U. pin terminals for damage or the connection of E.C.U. harness connector.
