INSPECTION PROCEDURE
1 Check voltage between terminal CCS of ECM connector and body ground.
PREPARATION:
(a) Remove the ECM with connector still connected.
(b) Turn ignition switch ON.
CHECK:
Measure voltage between terminal CCS of ECM connector and
body ground, when each of the -/SET, +RES and CANCEL is
turned ON.
OK:
Switch PositionVoltage
Neutral9 - 14 V
+/RES2.1 - 4 V
-/SET4 - 7.1 V
CANCEL6 - 10.1 V
OK Proceed to next circuit inspection shown on
problem symptom table (See page DI-991).

2 Check main switch continuity.
PREPARATION:
(a) Remove steering wheel center pad (See page SR-9).
(b) Disconnect the control switch connector.
CHECK:
(a) Measure resistance between terminals 4 and 5 of cruise
control switch connector when control switch is operated.
