TROUBLESHOOTING: “BEFORE YOU CALL” SECTION
VEHICLE STARTS BUT “CHECK ENGINE” LIGHT COMES ON OR ENGINE RUNS BADLY: (2 parts)
1. Many 1995-UP General Motors cars/trucks require a secondary ignition circuit for the Transmission computer
and other on board systems. If the vehicle is started without this wire energized, there may be a “Check Engine”
or “Service Engine Soon” light on the dash. This may cause damage if the vehicle is driven in this condition.
Check with installer to see if this circuit is present and has been properly connected to the system.
2. In some cases [commonly Nissan vehicles], an additional “Start” (Cranking) circuit is required for the vehicle to
run properly. The EZ-30 SERIES II system includes a wire that can be used for this Starter #2 circuit. Check
with your installer for details.
BATTERY REPLACEMENT
To replace the battery: Simply remove the screws on back of the transmitter and open the case. Remove the
