IQ SYSTEM TROUBLESHOOTING – TPS
on the black/white wire at a point close to the six-pin connector at the throttle position sensor. The reading should
be approximately 48-50 volts (full battery voltage).
3. If reading is zero volts, check the black/white wire continuity from the six-pin connector at the throttle position
sensor to the 16-pin connector at the speed controller. Check terminal positions in six-pin connector at the throttle
position sensor and the 16-pin connector. If all of the continuity readings are correct and the connectors are
wired correctly, replace the speed controller.
4. With multimeter set to 20 volts DC, place the black (–) probe on battery no. 4 (4 x 12-Volt battery set) or battery no.
6 (6 x 8-Volt battery set) negative post and the red (+) probe (with insulation-piercing probe) on the white wire at a
point close to the six-pin connector at the throttle position sensor. The reading should be approximately 4.65 volts.
5. If reading is zero volts, check the white wire continuity from the six-pin connector at the throttle position sensor
to the 16-pin connector at the speed controller. Check terminal positions in six-pin connector at the throttle
position sensor and the 16-pin connector. If all of the continuity readings are correct and the connectors are
wired correctly, replace the speed controller.
6. Turn key switch ON and, with multimeter set to 20 volts DC, place the black (–) probe on battery no. 4 (4 x 12-Volt
battery set) or battery no. 6 (6 x 8-Volt battery set) negative post and the red (+) probe (with insulation-piercing
probe) on the yellow wire at a point close to six-pin connector at the throttle position sensor. The reading should
be approximately 0.30 volts with the pedal up. Slowly press the accelerator pedal and note the readings on
the multimeter. As the pedal is pressed, the reading should increase until it reaches 4.15 to 4.45 volts when
the pedal is fully pressed.
7. If reading does not increase as the pedal is pressed, replace the accelerator pedal assembly. See Accelerator
Pedal Removal on page 5-6.
8. If the reading is not between 4.15 and 4.45 volts with the pedal fully pressed, the vehicle will not operate at rated
top speed. Replace the accelerator pedal assembly. See Accelerator Pedal Removal on page 5-6.
TEST PROCEDURE 5 – A1 and A2 Motor Voltage
See General Warnings on page 1-1.
1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack stands
under the frame rails just forward of each spring mount. See WARNING "Lift only one end..." in General
Warnings on page 1-1. See also following WARNING.
WARNING
• Keep people and equipment clear from rotating rear wheels. Do not allow persons under the car.
Contact with rotating rear wheels could result in serious personal injury.
2. With the batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on the A2
motor terminal (white wire) and connect the red (+) probe to the A1 (green wire) motor terminal.
3. With Tow/Run switch in the RUN position, place the Forward/Reverse switch in the FORWARD position, turn key
switch to the ON position and slowly press accelerator pedal.
4. As the accelerator pedal is pressed, the voltage reading should increase from approximately 5 volts RMS when
the throttle position sensor activates, to approximately 48 volts RMS with the accelerator pedal fully pressed.
See following NOTE.
NOTE: Voltage can vary depending on controller speed setting as well as which zone a Guardian equipped vehicle
is located.
Example: Speed setting 1 may only read 30 volts.
4.1. If there is no voltage reading, check the throttle position sensor. See Test Procedure 4 – Throttle Position
Sensor Voltage on page 11-16. Also check the continuity of the large posts of the solenoid. See Test
Procedure 22 – Solenoid Continuity on page 11-32.
