    • The SKSNG204D4T requires an EIS modification. Professional installation highly recommended. The EIS may be sent to Mid City Engineering for modification. Please contact Mid City Engineering at 312-421-1114 or sales@midcityengineering.com if you would like to send in the EIS

    • Click here for EIS modification instructions

    • Make sure that you are using the correct soldering equipment detailed in the EIS modification instructions. If incorrect equipment is used the EIS could be damaged. Board level soldering is required.

    • After EIS jumper is installed and EIS is reassembled, connect the EIS to the OEM harnessing and start vehicle with push to start and make sure that vehicle starts, runs, and operates normally and free from any errors before moving to the next step.

  1. The 10-pin green or white connector will need to be modified slightly to fit into the T-harness. See pictures. There is a small keying tab on the top of the connector. Using a small cutting tool, carefully cut off the keying tab flush with the shell of the connector. See pictures. Plug the modified blue or green 10-pin plug into the blue male 10-pin plug on the SKS T-harness

    • Connect blue female 8-pin connector from T-harness to rear of EIS where blue 8-pin factory plug was removed.

    • Start vehicle manually to verify vehicle is operating correctly and free from errors

    • If the vehicle does not start, check T-harness connections and make sure that module is plugged in. Verify that LEDs on SmartKey Starter module are on

  2. Remove battery from key Insert key in key box as shown in picture. The key must be in the positioning shown in the picture. If key is not positioned far enough forward into the bracket or too far forward, the remote start will not work
    • Remove battery from key

    • Insert key in key box as shown in picture. The key must be in the positioning shown in the picture. If key is not positioned far enough forward into the bracket or too far forward, the remote start will not work

    • Close and secure key box lid with provided screws

    • If the key box lid is not closed and any light is getting into the box, the remote start will not work.

    • Connect 20-pin connector from T-harness to 20-pin connector on SKSNG module

    • Plug 2-pin white plug from supplied key box to 2-pin white connector on SKSNG module labeled KEY

    • Make sure that vehicle is in safe position to start

    • To test remote start, press the panic button on the OEM remote 1X

    • If the OEM key does not have a panic button, use LOCK-UNLOCK-LOCK sequence from OEM key to remote start

    • The same control on OEM key (panic button or L-U-L) to remote stop

    • Remote start vehicle. Once vehicle is started, to perform key takeover press the push to start button 1X

    • Parking lights will flash 3X and vehicle can be shifted into gear.

    • Remote start vehicle

    • Once vehicle has remote started, press the brake pedal and confirm that vehicle shuts down

    • Open hood

    • Using factory remote, press and release panic button (1) time or press LOCK-UNLOCK-LOCK if no panic button and confirm vehicle does not remote start- parking lights should flash (7) times

    • Re-install the EIS in the dash

    • Use zip ties to mount key box module and SmartKey Starter module together

    • Compustar Drone: Connect to the GRAY 4-Pin port labeled DRONE on the SmartKey Starter module.

    • Directed Smart Start: Connect 4-pin D2D cable from Smart Start to white 4-pin port labeled D2D on the SmartKey Starter module. Cut and insulate blue and green data wires (leaving only black and red for power and ground.

    • Connect 3-pin ESP plug from Smart Start to 3-pin white plug on SmartKey Starter labeled Smart Start. Do not ground gray wire from Smart Start.

    • Compustar DAS II sensor: Connect to 4-pin RED port labeled SENSOR on the SmartKey Starter module

    • Compustar RF remotes: Connect Compustar antenna to 4-pin BLUE port on the SmartKey Starter module labeled 4PANT

    • AM remotes are NOT supported

    • Compustar remote programming: Cycle key from off to ignition 5X- parking lights will flash 1X after the 5th cycle. After the 5th cycle, press the button on the antenna (if antenna has a button) and press LOCK on each Compustar remote. Parking lights will flash when each remote is paired. Parking lights will flash 2X when exiting programming

    • Directed RF remotes: to add Directed remotes, a Directed XL202 RF to data converter must be used. Connect the XL202 to the 4 pin white plug labeled D2D on the SmartKey Starter module. Connect Directed RF antenna to XL202 and follow XL202 programming instructions

    • Remote starter must be turned off (valet mode) any time the vehicle is being serviced or undergoing any diagnostic tests or parked in a location where it is not safe for the vehicle to start

Conclusion

Troubleshooting:

If vehicle receives the command, but fails to remote start, the parking lights will flash a # of times. The number of parking light flashes corresponds to an error code. To troubleshoot no remote start count the number of parking light flashes.

Note: after a brief pause, the error code may be followed by a shutdown sequence of 3X flashes after the initial code

Error codes:

4 Flashes: Valet mode. The remote start is in valet mode (remote start off). Click here for valet mode instructions using the instrument cluster menu.

5 Flashes: Wrong variant. Power cycle modules and try again.

6 Flashes: Brake depressed. The vehicle sees that the brake is depressed. If the brake pedal is not pressed down, it is possible that the brake switch is out of alignment. Check brake switch above brake pedal. If brake switch is out of alignment, you may see brake lights on all the time when the vehicle is started.

7 Flashes: Hood open. The remote start will not work if the hood is open or latch is not fully closed.

8 Flashes: RPM overrev. Vehicle sees that RPM is too high.

9 Flashes: Not seeing the key.

Check key box and connections:

Verify placement of key. If key is too far forward in key box or not far enough forward, there will be a key error.

Check to make sure 2-pin white port is plugged into SKS module and RJ cable from EIS is connected to key box. Make sure connections are secure.

Make sure key box is fully closed and secure and no light is entering key box.

Check EIS connections:

If there is an issue with the EIS modification, there can be a key error (9 or 11 flashes).

10 Flashes: Communication error. Check connections and power cycle module.

11 Flashes: Not seeing the key.

See 9 flashes (same error)
