APPENDIX 1
PROCEDURE TO TEST SPEED SENSOR EXTENSION
CABLES
Disconnect extension cable from Speed Sensor Assembly cable. Hold extension cable connector
so that keyway is pointing in the 12 o’clock position.
PIN DESIGNATIONS
Pin 1 is ground.
Pin 2 is signal.
Pin 3 is power.
Pin 4 is not used.
VOLTAGE READINGS
1) Pin 1 to pin 2 = +5 VDC.
2) Pin 1 to pin 3 = +12 VDC.
PROCEDURE TO CHECK CABLE:
1)
Enter SPEED CAL number of 9999 in key labelled
2)
Depress key labelled
3)
With small jumper wire (or paper clip), short between pin 1 and pin 2 with a "short-no short" motion.
Each time a contact is made, the DISTANCE total should increase by increments of 1 or more counts.
4)
If DISTANCE does not increase, remove the section of cable and repeat test at connector next closest
to Console. Replace defective cable as required.
5)
Perform above voltage checks.
6)
If all cables test good, replace Speed Sensor.
NOTE:
After testing is complete, re-enter correct SPEED CAL number before application.
