B. Auxiliary Speed Sensor ([SIGNAL GENERATOR or MAGNET & COIL PICK-UP KIT (KIT# 250-4165)] Raise
one (1) of the vehicle drive wheels (both drive wheels on a limited slip differential) and block the non drive wheels.
Use a support stand for safety. Spin the drive wheel by hand as fast as possible (You must spin the wheel at least
4.8 KPH (3 MPH) or faster in order to test an auxiliary speed signal.) The LED should flash and continue to flash at
the same rate. If so, continue to Step 9; if not, go to Step 8Bi.
i. Check steps to entering Diagnostic Mode and test again.
ii. Check Programming Switch# 10. It should be OFF for Sine Wave Input. If set incorrectly, reset and reenter
Diagnostic Mode.
Step 9:
Your Cruise Control 2 has successfully passed the Self Diagnostic Testing Procedure. If it still does not function, test
your TACH signal.
X. TACH SIGNAL TESTING PROCEDURE
Step 1: Turn the cruise control switch OFF.
Step 2: Turn the ignition to the OFF position.
Step 3: Standard Control Switch (all except HND-2): Press and hold the RESUME/ACCEL button while you
turn the ignition switch to the ON position and start the engine. Now release the the RESUME/ACCEL slide
switch.
HND-2 Control Switch: Turn the ignition switch to the ON position and start the engine, hold the
RESUME/ACCEL button down while you turn the cruise control switch to the ON position.
Step 4: The Diagnostic LED should be flashing. Rev the engine, the LED should flash faster at higher RPM's.
If so, your TACH signal is valid, if not, go to Step 4a.
a. Check steps to entering Diagnostic Mode and test again.
b. Either your TACH wire is incorrect or your connection is bad. Inspect your TACH connection and
reenter Self Diagnostic Mode.
XI. CONTROL SWITCH TESTING PROCEDURE
Utilize the following continuity charts to test your control switch if you suspect that it is not functioning
properly. You need to unplug the 10-pin connector from the CRUISE MODULE to perform these tests.
1. Ground the test light lead and verify that the light works by probing a known power source.
2. Follow the test charts below using the appropriate chart for your control switch.
