CM6200 Install Guide
STEP 1: Start the vehicle with the key. Allow time for the engine to idle down.
STEP 2: Test wire and make connection. At idle the tach wire should test between 1 to 4 Volts AC. As the
vehicle RPM's increase the voltage on the meter will also increase. Always solder tach connections.
STEP 3: Learn tach. While the vehicle is at idle, hold the foot brake and activate the remote start function
on the remote control for 2.5 seconds. The
parking lights will flash once and the siren will
chirp once to confirm a good tach signal. The
parking lights will flash two times and the siren
will chirp two times to indicate the tach did not
learn. Two seconds following the two flashes,
the number of parking light flashes will indicate
the cause of the error:
Alternator Sensing
Alternator sensing is an alternative method the remote start can utilize to determine if the engine is running.
This is different than the no tach sensing mode so a connection must be made. IMPORTANT: The remotes
must be coded prior to setting up alternator sensing.
STEP 1: Change Option 2-10 to setting 2 - Alternator sensing.
STEP 2: Test wire and make connection. The stator wire is found at the vehicle's alternator. Change your
multimeter to DC voltage before testing for this wire.
A. At rest, with the ignition off, the stator wire should test 0V DC.
B. Turn the ignition to the run position. The stator wire should now test between 4 – 6V DC.
C. Start the vehicle with the key. The stator wire should now test between 12 – 14V DC at idle.
STEP 3: Process complete – no further programming is required.
Tachless Mode – (Automatic Transmission Vehicles Only)
Tachless sensing is an alternative engine sensing mode. It does not require a connection to the vehicle other
than the main ignition harness.
STEP 1: Change Option 2-10 to setting 3 – No tach sensing.
STEP 2: Process complete – there is no further programming required other than adjusting crank time
when necessary (see below).
Adjusting Crank Time: To adjust minimum crank times, refer to Option 2-12. To help ensure successful
starting, the system will automatically add additional crank time to the 2nd and 3rd start attempts. In
addition, there is a built in "Smart Resting Mode". Traditional tach sensing is still highly recommended for
colder climates.
