ADDITIONAL TESTS FOR EEC-IV SYSTEMS - RELAY AND SOLENOID TEST
If the CanOBD2&1 Scan Tool fails to
link to the vehicle's computer, a
"Vehicle is not responding" message
shows on the CanOBD2&1 Scan
Tool's display. Do the following:
- Verify the ignition is ON.
- Check the cable connections at
the Code Reader and at the
vehicle's DLC.
- Turn the ignition OFF, wait 10 seconds, then turn back ON to
reset the computer.
- Press ENTER/LD
9. If the CanOBD2&1 Scan Tool was able
to link to the vehicle successfully an
"Output State check active..." message
shows temporarily on the CanOBD2&1
Scan Tool's display. This message is
followed by a display that instructs you
how to perform the test.
10. Press the accelerator pedal once, then release. This activates the
Output State Check and energizes most of the actuators (relays and
solenoids) that are controlled by the vehicle's computer.
If your vehicle is equipped with an Integrated Vehicle Speed
Control, disconnect the vacuum supply hose from the speed
control servo before pressing the accelerator. Reconnect
vacuum hose after test.
11. To de-energize the actuators, press the accelerator pedal again and
release, the actuators are now de-energized.
12. The procedure can be repeated as many times as desired by
pressing and releasing the accelerator pedal to energize and de-
energize the actuators.
13. Consult the vehicle's service repair manual for a list of actuators
(solenoids and relays) controlled by the computer that apply to the
vehicle under test, and which actuators should energize and de-
energize when performing the Output State Check. All applicable
actuators should be on when energized and off when de-energized.
14. If an actuator is not responding to the Output State Check, follow the
procedures described in the vehicle's service manual to check
computer actuator output circuit voltages and/or grounds.
15. The Output State Check will stay active as long as desired. To quit
the Output State Check, turn the ignition OFF and disconnect the
CanOBD2&1 Scan Tool from the vehicle.
