CRUISE CONTROL SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step Check Yes No
1 CHECK IGNITION SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the ECM harness connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(B137) No. 14 (+) — Chassis ground (
−): Is the voltage more than 10 V? Check the poor
contact of ECM
connector. Check the fuse
No. 11 (fuse &
relay box).
 Check the har-
ness for open or
short between
ignition switch and
ECM.
