DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Cruise control system is electronically and vacuum
controlled. System components include a control unit, actuator, vacuum
pump, cruise control switch, clutch pedal position switch (M/T),
cruise indicator light, diode, Park/Neutral (P/N) switch (A/T),
stoplight switch, vehicle speed sensor and A/T control unit (if
equipped).
System has self-diagnostic capability. When self-diagnostic
mode is activated, each switch and sensor is checked for defects. When
cruise control system has been canceled without using a normal cancel
method, a trouble code will be set and stored in control unit. Trouble
codes can be retrieved to help determine which circuit is
malfunctioning.

INSPECTION PROCEDURES FOR TROUBLE SHOOTING SYMPTOMS
Test No. 1
Defect in power supply system (including ground) for
diagnostic line may be possible. Probable causes are:
* Malfunction of connector.
* Malfunction of harness.
1) Check voltage between data link connector pin No. 16 and
ground. See Fig. 35. If battery voltage is present, go to next step.
If battery voltage is not present, check junction block connectors C-
81 and C-94. See Figs. 19, 21, 26 and 27. If connectors are defective,
repair as necessary. If connectors are okay and malfunction remains,
check harness between power supply and data link connector. Repair as
necessary.
2) At data link connector, measure continuity between pin No.
4 and ground and pin No. 5 and ground. If continuity is present,
replace scan tool. If continuity is not present, check data link
connector for damage or loose connections. Repair as necessary. If
connector is okay and malfunction remains, check harness between data
link connector and ground. Repair as necessary.
