REMOTE START TROUBLESHOOTING Cont.
ENGINE CRANKS VEHICLE BUT VEHICLE NEVER STARTS:
1. In some vehicles, there may be a Factory anti-theft system that will not allow the engine to run without the key in
the ignition. These systems may include Factory Security Modules, GM Passkey®/Passlock®, and RF
Transponder systems (Ford P.A.T.S.®). Many late 1990’s, 2000 and Later vehicles may include some type of
Anti-Theft system. Check vehicle owner’s manual to see if the vehicle equipped with a security system.
2. The vehicle may have more than one Ignition/or Accessory circuit that requires power for the vehicle to start.
This is common on some Toyota vehicles where (2) Ignition “ON through cranking” wires are required.
VEHICLE STARTS BUT CHECK ENGINE LIGHT COMES ON OR ENGINE RUNS BADLY:
1. Many 1995-UP GM cars/trucks require a secondary ignition circuit for the Transmission computer. If the vehicle
is started without this wire energized, the vehicle will display a “Check Engine” or “Service Engine” light on the
dash. This may cause transmission damage if the vehicle is driven. Be sure to check for any additional WHITE
(or GREEN) Ignition wires on GM cars and trucks that power up when started with the key.
2. Some Vehicles [Commonly Nissan] require 2 Start (Cranking) circuits for the vehicle to run properly. If this is the
case, then an additional relay must be installed with the output connected to the extra starter wire in the vehicle.
NO RESPONSE TO/FROM REMOTE:
1. Check for proper power/ground wiring connections.
2. Check Antenna Module connection. The antenna included with this system must be plugged in to send/receive
signals. Antenna Module gets voltage from the control module. See antenna diagrams on Page 30.
3. The Remotes may need to be reprogrammed to operate the system. See Transmitter programming.
