If you have the OBDLink Bluetooth (link) and planning on installing it permanently in your truck, here is what I did:
1.) Download the necessary software and tools:
-STN Term (at the bottom of the page)
-The most recent firmware version (I used 2.2.2)2.) Update the firmware:
-connect the OBDLink via usb to the computer
-extract (unzip) the downloaded firmware
-run "StnFirmwareUpdater.exe" from the extracted file
-make sure the correct com port and firmware file are selected and select "upload firmware"
-if it succeeded close the updater.3.) configure the sleep settings:
-run "stnterm.exe" you downloaded.
-select the correct com port and click ATI, you should get a response with the current version
-type in "STSLVLW >14.00, 2" (this wakes the device if the voltage is greater than 14 volts for 2 seconds) click send, you should get a "ok" response.
-type in "STSLVLS <13.80, 30" (this will put the device in sleep state if the voltage is less than 13.80 volts for 30 seconds) click send, you should get a "ok" response.
-type in "STSLVL on,on" (this turns on both voltage sleep and wake triggers) click send, you should get a "ok" response.4.) verify that the settings and commands worked:
-click "ATZ" in stnterm (this reboots the device) you should get a "ok" response.
-type in "STSLCS" (this shows the current power save settings) click send, you should get a list that should look like this:5.) Make sure it works:
if all the settings look correct you are good to go.Code:CTRL MODE: NATIVE PWR_CTRL: LOW PWR = LOW UART SLEEP: OFF, 1200 s UART WAKE: ON, 0-30000 us EXT INPUT: LOW = SLEEP EXT SLEEP: OFF, LOW FOR 3000 ms EXT WAKE: ON, HIGH FOR 2000 ms VL SLEEP: ON, <13.80V FOR 30 s VL WAKE: ON, >14.00V FOR 2 s VCHG WAKE: OFF, +0.20V IN 1000 ms
-Plug it into your truck and watch the alternating led, if it goes off after 30 seconds it is in sleep mode.
-Start the engine, the led should come on and alternate again.
-Your good to go!
I did this with a 2011 V6 WITH the tow package (larger battery and alternator), you may have to adjust the voltages to your truck.
If at any time the commands do not reply with "ok" use the ATZ to reboot the OBDLink at try the command again.
I am using a DROID2, I have both DashCommand and Torque for Android. (they both work with the OBDLink)
Any questions just ask
