Question about 2006 Jeep Commander
OD'd on OD? sigh.
OD is a tranny function. (top gear, overdriven ratio)
the lamp can also show failures.... (old cars, where is this lamp>?)
all this is in the operators guide, in the glove box.
read the lamp and its modes of operation. and warnings.
07 is here, my be same,,, probably
page 134 , tow-haul switch set wrong? ERS option ! only.
does car have the EVICs display that gives message warnings?
like transmission overheated, etc.?
OD operation is complex. 4s or 5speed.
it can drop out with too cold and engine, or in 4wd.
speed, load and other conditions. including
Is the Check Engine lamp glowing , running? if yes scan it.
as this lamp also reports transmission errors. pg 176.
is your car 2wd or 4wd? ?
conditions for OD
normal engine/trans temperatures.
tow-haul , switch off.
out door temps not too cold. page 260
advice: What is the CEL doing and are all fuses good.
1: this car uses, CAN buss, a car digital network.
it can have errors, and if the OD function is acting up
the book says, do the CAN diagnostics to see if there are errors
from the Display system called CLuster, and the BCM/PCM or tranny functions.
there are 2 tranmissions ( RFE or NAG?)and 3 engines and diff, 2wd/4wd systems options. non of which were stated.
nor exactly where this light is? they never mention it in the opr guide.
