Viper 4811V Owner's Manual page 52

Troubleshooting: Keyless Entry
System does not Auto re-lock:
1. Is Auto re-locking programmed ON?
2. Are the door inputs connected? Either the 24-pin harness Green or Violet door trigger wires should
be connected.
Door locks operate backwards.
• This unit has easily-reversed lock/unlock outputs. Recheck wire connections to see if you have reversed
these.
Troubleshooting: Remote Start
The remote will not activate the remote start.
1. Check remote startup diagnostics.
2. Is the remote start shut OFF switch plugged in and turned ON?
3. If the vehicle has an automatic transmission, make sure the remote start is programmed for
Automatic Transmission mode.
4. Is the remote programmed to the system?
5. Can the remote start be activated manually by applying a ground pulse to the 24-pin harness
White/Blue activation input?
6. Check the harnesses and their connections. Make sure that the harnesses are completely plugged
into the remote start module. Make sure there are good connections to the vehicle wiring.
7. Check voltage and fuses on the main 6-pin harness and on the heavy gauge remote start harness.
The remote start will activate, but the starter never engages.
1. Check for voltage on the Violet starter wire two seconds after the remote start becomes active. If
there is voltage present, skip to Step 8. If there is not voltage present, advance to Step 2.
2. Check the 30A fuses.
3. If the Gray/Black wait-to-start wire is detecting ground upon activation, the starter will not crank.
4. Is the tach wire connected? If so disconnect it and remote start the vehicle to see if the Violet wire
sends out voltage. If you get voltage you will need to go to an alternate tach source, the tach wire
you are currently on has a voltage spike upon ignition power up which can cause the remote start to
not send out the crank voltage.
5. Is the vehicle a Chrysler or GM with a multiplexed starter wire? The vehicle will not crank if the
resistance is incorrect on the multiplexed accessory/starter wire.
6. Is the vehicle a GM? If so the Brown accessory needs to be powered up on some of the vehicles for
the vehicle to crank.
7. If this is a manual transmission vehicle, the clutch will need to be bypassed (see Tech Tip # 10000 at
www.directechs.com)
8. Make sure the Violet starter wire is connected on the starter side of the optional starter disable/anti-
grind relay.
9. Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank
if active.
10. Check connections. The heavy gauge remote start input wires on the heavy gauge 10-pin connector
should have a solid connection.
The vehicle starts, but immediately dies.
1. Does the vehicle have an immobilizer? The vehicle's immobilizer can cut the fuel and/or spark
during unauthorized starting attempts.
2. Is the remote start programmed for Virtual Tach or voltage sense? If so, the crank time may not be set
long enough. Voltage sense will not work on some vehicles.
3. Is the remote start in tach mode? If so has the tach been programmed to the system?
4. Check diagnostics. Sometimes a shutdown will become active during cranking or just after cranking.
