V 8.3 pcbv7.3/8.1 AutoCommand® “Add-On” Remote Control Car Starter Model 20022 Installation Manual For use on automatic vehicles only. For gasoline or diesel vehicles. 7955 Cameron Brown Court Springfield, Virginia 22153 USA www:designtech-intl.
LIMITED WARRANTY Congratulations on your purchase of the AutoCommand® Remote Car Starter. The AutoCommand® Remote Car Starter system allows you to start the car by remote control from the comfort of your home or office in order to cool it down in the summer or heat it up in the winter. DesignTech International, Inc.
Important Note: Make sure that all drivers who will be operating the AutoCommand® are fully aware of the safety precautions installed and their limitations. Stress the importance of switching the On/Off control switch to the “OFF” position (down) every time the car is serviced. Show the user how the control switch must be turned off and on again after pulling out the key before leaving the car.
1. Remove the top and bottom halves of the steering column shroud. 2. Locate the small three wire harness (with White, Black and Yellow wires) running down from the ignition key cylinder on the top right hand side of the steering column into the instrument panel. 3. Cut the Yellow wire in half and bare back the Black wire. 4. With the ignition key in and turned to the “ON” or “RUN” position, measure the resistance between the key side of the Yellow wire and the Black wire.
Most of the 1990-1995 Cadillacs have a slight variation on the wiring for the VATS system. On these cars, there is an ORANGE wire (actually a vinyl sleeve) that contains smaller wires. This is located underneath the steering column next to the YELLOW sleeve that is labeled “Air bag wiring” -- do not cut this Yellow sleeve. Slit the ORANGE sleeve open to expose two pairs of wires which are either both white, OR both yellow, OR both black.
POWER & IGNITION WIRES C. You can choose the next option by pushing the left button again to index to the next option. When you get to the next option you want to change, simply repeat Step B above. After six seconds, the AutoCommand® automatically exits the programming mode (Three LED flashes). The AutoCommand® module will be installed under the dash once all wiring has been completed. Do not mount the module at this time! You will need to check the diagnostic light (LED) as the installation progresses.
#1 sets the starting method. The factory setting uses “No-Tach” starting. If you wish to use the tach to start, follow the instructions in 12A. #2 is for the choice of run times. 4 Blue Wire (14 AWG) Ignition 1 Connect the LIGHT BLUE wire to the ignition 1 wire of your vehicle. This wire will measure +12V on the test meter in the “run” and “start” position, and is off (ground) in the “lock/off” and “accessory” positions). #3 will add 50% more crank time to “No-Tach” starting.
Control Harness (All wires are the smaller 18 AWG size) 9. Violet Wire 20. Trouble Shooting with the Self Diagnostics Hood Pin Switch Control Harness The hood pin switch MUST be installed with the AutoCommand®. It prevents operation of the AutoCommand® when the hood is open. Connect the VIOLET wire to the hood pin switch using the red connector.
16. Brown Wire Acc. Pulse Control Harness The optional BROWN wire is the Accessory Pulse output which gives out a 1 second transistor ground output just as the Accessory wire comes on. This is important in some vehicles to control the defroster or to control the GM R.A.P. system. Again, this is a 400 mA transistor ground output which MUST drive a relay (not included). 17.
OPTIONAL STEPS 12A. Tach Rate Learning Note: Only use if the tachometer sensing method is chosen. A. B. C. D. E. F. G. H. I. Many of the optional steps require a relay to be hooked up. The most common relay used for this type of application is the Bosch type automotive relay P/N 0332 209150. Use the diagrams below for a typical hookup. If you use another type of relay, then you need to know that pins 85 and 86 in this diagram represent the coils of the relay.
