Fig. 143 Inspect the solenoid relay operation while applying
battery voltage—1994-97 models
- Connect a jumper wire from the positive battery terminal to terminal
- Connect a jumper wire from the negative battery terminal to terminal 3 of
the relay. - Using an ohm meter, check for continuity between terminals 1 and
2 of the relay. Replace the relay if the test results indicate no continuity. - To inspect the solenoid relay circuit, with the relay off of the actua-
tor, check for continuity between terminals 1 and 6. - Check that there is no continuity between terminals 2 and 5.
- Check that there is continuity between terminals 3 and 5.
- Connect the positive lead of an ohmmeter to terminal 5 and the neg-
ative lead to terminal 4 of the relay. There should be continuity. Reverse the
leads of the ohm meter and observe the readings. There should be no con-
tinuity. - If continuity readings differ from specified results, replace the relay.
REMOVAL & INSTALLATION
The control relays are located in the actuator. There is a plastic case sur-
rounding them, remove this case and unplug the relays.
Speed Sensors
TESTING
I See Figures 144,145 and 146
- Inspect the sensor. Disconnect the speed sensor wiring.
- Measure the resistance between terminals. Standard resistance
is:
- Front—0.6-1.8 kilometers
- 1.05-1.45 kilometers
- If the resistance value is not within specifications, replace the speed
sensor. - Check that there is no continuity between each terminal and the sen-
sor body. - If there is continuity, replace the sensor.
- Connect the speed sensor wiring.
