Each XPRESSSTART is equipped with a (4) pin and a (3) pin connector at the end.
The (4) pin connector is designed to accept a D2D cable from an XL202 RF translator module to provide the ability for adding long
range remotes and 2 way capability to the XPRESSSTART. There is no programming required for the module. The remotes need to
be programmed to the XL202 which should have instructions provided with it.
The (3) pin connector is designed to accept the ESP cable that comes with the Directed SmartStart module (DSM100, DSM200 or
DSM250). The cable can be plugged directly in to the port. The power and ground must be connected (soldered and taped) to the
XPRESSSTART harness. Please see the below diagram. DO NOT USE THE 4 PIN PLUG ON A SMARTSTART MODULE.

Troubleshooting Diagnostic Flashes
While running on remote start, any of the following will cause vehicle shut down.
•opening the hood (7 flashes)
•depressing the brake pedal (6 flashes)
•increasing the RPM over normal idle (8 flashes)
•three failed starts/low RPM (9 flashes)
•communications error (10 flashes)
The vehicle will be limited to (5) remote starts between normal keyed operation.
If the lights flash (5) times the starter is out of sync with the vehicle. This is a rare occurrence. Should it happen, you must start the
vehicle with the key or the KeylessGo button for at least one minute to synchronize.
