Entering and Using the Speedometer Diagnostic Mode
You can use the speedometer diagnostic mode to check/reset several indicators, icluding the service interval light (that little wrench you wish would go away but don't know how to reset).
A couple things to know: First, the wrench displays as long as you are in diagnostic mode. Second, THE DIAGNOSTIC MODE REQUIRES THE TRANSMISSION TO BE IN NEUTRAL. If the speedo isn't displaying an "N" in normal mode, then the speedo can't tell if the machine is in the right gear. This will cause the diagnostic mode to not come up when you turn the key on. It also means you will have to check these circuits the old fashioned way.
1. Turn key off for 10 seconds. Place the gear lever in the Neutral position and set your parking brake.
2. Hold Reverse Override button in while turning key on (don't start the engine). You can let it go after the key is on.
3. First you should briefly see a screen that displays the software version loaded on the ECU then it will move to Screen 1. If you use the Reverse Override button it will scroll through the diagnostic screens just like when you are selecting the tach, odo, & hours in normal mode.
Screen 1 = Battery Voltage
Screen 2 = RPM (will indicate "0" unless you started the engine upon entering diagnostic mode, which is OK to do).
Screen 3 = AWD Diagnostics. Tells you whether there is power going to the AWD coil when you move the switch.
Screen 4 = Gear Circuit Diagnostics. Since you are in neutral, the initial value should be screen that brings up the "N" gear indication and the number 158, or close to it. This screen is telling you how much resistance in ohms the gear indicator switch has for a given gear. Move the shift lever to each gear and the corresponding letter and resistance value should pop up as you land on each gear.
P = 23
R = 75
N = 158
L = 297
H = 628
The speedo translates these values into a gear indication on the LCD. The manual says a 10-20% variation is OK. If any of the indications are “0” it could be wiring or the switch. If there is a value other than “0” and out of spec then you need a new switch. It's an easy 5 minute job but the switch is a bit pricey. Also, the speedo controls the AWD engagement. If your speedo isn't showing a "L" or "H" then your AWD isn't engaging in that range. The workaround in a pinch is to hold the Reverse Override button when you need AWD in the forward ranges. That's only in the forward ranges. AWD still won’t work in “R” if the speedo won’t display the “R”.
Screen 5 = Programmable Service Interval Setting. Resets the wrench light. To reset it or to set it to a different interval, hold the Reverse Override button in until the wrench flashes and release it. Use the button to set it to the deisred interval. To exit just wait until the wrench light stops flashing. To disable it, hold the button in for 7 seconds until the word "OFF" appears.
Screen 6 = Miles/Kilometers Toggle. Hold the button in until the letters flash. Use the button to select the desired reading. Wait until the wrench stops flashing and it is set.
