The data bypass kit's LED does not turn on when the module is plugged in. The bypass kit is unable to power up. Either there is no power (+12vDC) on the red wire, or no ground (0vDC) on the black wire. Measure the voltage across these terminals and ensure the unit is getting 12vDC when the vehicle is idle, during crank and running with the key.
The data bypass kit's LED remains on when programming and never goes out. The bypass kits output data wire wire is not connected to pin #2 of the vehicles OBDII connector (violet) under the dash, or the bypass kits ground-out-while-running input wire is always at ground even when the remote-starter is shut down. If the battery of the vehicle is disconnected or drops below 3vDC the bypass kit will lock itself and once the battery is reconnected the vehicle will need to be started with the key at least on...
The vehicle's horn honks everytime the remote-starter or aftermarket alarm sends a lock and/or unlock pulse to the bypass kit. (A) The bypass kit is receiving a double-lock or double-unlock pulse from the remote-starter or after-market alarm. (B) The remote-starters unlock & disarm or lock & rearm wires are connected together to the bypass kit which will cause the bypass kit to receive a double-lock and/or double-unlock pulse depending on the timing of the remote-starters outputs. (A) Reprogram the...
The bypass kit programs successfully and the remote-starter is able to start the vehicle numerous times until the dash and/or steering column cover is re-assembled at which time the remote-starter is no longer able to bypass the PATS/Transponder system. The PATS/Transponder ring has been misplaced or damaged during the re-assembly process. Disassemble the steering column cover and inspect the bypass kits transmission ring. Depending on the ring being used... (A) If the bypass kit's ring is a copper c...
The installer is unable to program the bypass kit's onboard transponder into the vehicle's BCM (Body Control Module). In the majorority of these cases the remote starter timing is not fast enough to enable the vehicle's ignition and the bypass kit's transponder output so the vehicle's BCM times-out in the middle of the installation programming procedure. The vehicle and bypass kit will need to be 'hot-wired' near the end of the programming sequence in order to enable the Bypass kit's output before the B...
The bypass kit is unable to lock and/or unlock the vehicle. The connected remote-starter or alarm does not have a perfect ground on the lock/unlock signal. Some modules have short-circuit protection by using either an internal diode, transistor, or resistor which prevents the lock/unlock output pulse from having a ground that is at a low enough potential for the bypass kits' input to recognize. Try grounding the bypass kits' lock/unlock input manually to chassis ground. If the locks function properly th...
The bypass kit will not program while the data portion (if applicable) may work on some vehicles. The internal transponder on these bypasskits can only be programmed once. When they are programmed into the vehicles' control module they are slightly modified and cannot be used again. Some distributors were unaware of this, and there have been a few reports where there have been some used bypass kits recirculated back to our customers. This problem should be assumed as a last resort. If all else fails it...
