Not positive, but i think its because of the TPMS (tire preasure monitoring system) on the car. If the tpms valve stems were removed and replaced with normal valve stems then the car will register 0 psi in the tires, causing the alarms. Once again im not a mechanic but i think thats what your problem is.

I was driving my 2007 acura rdx when I noticed the sh-awd light on. I then saw the check engine light on. Later when I turned my car on again the check engine light was still on, not the sh-awd light. ...


The SH AWD uses electromagnetic clutch in the back drive axle to change the power distribution to the rear wheels. It would have nothing to do with the P0171 error. What TPMS valve stem was bad? Because this could be a clue to what the problem is. If a rear tire is having issues it could cause the sensor to make adjustments to the system to compensate for the tire. The person that changed the TPMS might have also caused the issue when they worked on the tires.

2wd vs AWD


Page 13 of owner's manual says:
AdvanceTrac
(if equipped):
Illuminates when the AdvanceTrac
system is active. If the light remains
on, have the system serviced
immediately.
AWD locked (if equipped):
AWD
Illuminates when all wheel drive
LOCKED
(AWD) is engaged/activated. If the
light continues to flash, have the
system serviced.

Page 224:
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with an All Wheel Drive (AWD) transfer
case. With the AWD option, power is supplied to all four wheels
automatically with no need to shift between two-wheel drive and
four-wheel drive. If your vehicle is equipped with the AdvanceTrac
stability enhancement feature, you can change AWD modes, if desired,
by selecting AWD options through the message center.
For the lubricant specification and refill capacity of the AWD transfer
case refer to Maintenance and specifications chapter.
If your vehicle is equipped with AWD, a spare tire of a different
diameter than the road tires should never be used. Such a tire
could make the vehicle difficult to control as well as result in damage
to driveline components.
Utility and four-wheel drive vehicles are not designed for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
The following sections, Normal operation, Autolock operation and
Disabling AWD, apply only to vehicles which allow the driver to change
AWD modes through the message center.
Normal operation (vehicles equipped with AdvanceTrac
During normal operation:
• the AWD system is in AWD AUTO mode (AWD LOCKED will
illuminate in the message center for four seconds when you first start
your vehicle). The AWD LOCKED indicator in the instrument cluster
will also come on.
• AWD AUTO mode can be overridden by pressing SETUP in the
message center. When you first press SETUP, AWD <AUTO> will be
displayed, then if you press RESET within four seconds of pressing
SETUP, AWD <LOCKED> will be displayed. AWD <LOCKED> provides
power to all four wheels constantly which allows you to operate your
vehicle in severe winter or off-road conditions such as deep snow, ice
or shallow sand. It is not recommended that you use AWD <LOCKED>
on dry pavement.

Page 225:
• AWD <LOCKED> can be cancelled by pressing RESET in the message
center. (The AWD LOCKED display in the message center will then
turn off and the display will return to AWD <AUTO> for four seconds
when the shift is complete.)
Autolock operation (vehicles equipped with AdvanceTrac
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
• the AWD LOCKED indicator light will illuminate in the instrument
cluster and AWD DISABLED <LOCKED> will be displayed in the
message center.
• AWD LOCKED will be displayed in the message center for four
seconds and a warning chime will sound. This condition may clear
without any action being taken by the driver.
• the AWD LOCKED indicator light in the instrument cluster will turn
off when the AWD system cools down.
• When the system is sufficiently cooled down, AWD AUTO RESTORED
will appear in the message center for four seconds and a warning
chime will sound.
Disabling AWD (vehicles equipped with AdvanceTrac
When a problem is detected in the AWD system:
• the AWD LOCKED indicator light in the instrument cluster will flash
eight times every two minutes in the message center.
• The message center will then display AWD DISABLED for four
seconds, then SEE OWNER'S MANUAL. A warning chime will also
sound. The warning displays and chime will continue until RESET is
pressed (which will clear the message from the display).
• AWD LOCKED can still be engaged by pressing SETUP (the message
center will display AWD <DISABLED> LOCKED), then pressing
RESET. The AWD LOCKED indicator light will illuminate in the
instrument cluster and the message center will display AWD
DISABLED <LOCKED>.
• To disable AWD, press RESET. The system will go back to AWD AUTO
mode momentarily, then the AWD LOCKED indicator light will flash in
the instrument cluster eight times every two minutes. The display will
then show AWD <DISABLED> LOCKED for four seconds and then
turn off.

Page 226:
• If a serious problem occurs with the AWD system, the AWD LOCKED
indicator light in the instrument cluster will flash 10 times every two
minutes. The message center will also display CHECK AWD and a
warning chime will sound. You can press SETUP to check the status of
the AWD system (which will display AWD <DISABLED> LOCKED),
but the AWD system will be disabled until the system is serviced.
Driving off-road with truck and utility vehicles
AWD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
When driving at slow speeds off-road under high outside temperatures,
use 1 (First) gear when possible. 1 (First) gear operation will maximize
the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

Abs /vsa light on


A direct-sensing type Tire pressure warning system is used in TPMS
If the vehicle continues to be driven with 1 or more of the 4 inflated to a low air pressure that could cause problems during driving, this system will illuminate the tire pressure warning light to inform the driver of the low air pressure.
In addition to that, this system directly senses the air pressure of each Tire through Tire pressure warning system valve & transmitter that are attached to each wheel.
Before you could proceed you are required to please retrieve the error codes and freeze frame data to get to know about the problem.

If one tire is damaged do you need to replace all four tires on an AWD.


Not really.
While it is recommended by most auto makers and tire companies to replace tires in sets of 2 or 4 it is not a requirement.
As long as the tires are all the same size and style, you should be ok with replacing just one.

VSA shows on my dash and the vehicle seems to remain in the same gear. It can&#39;t accelerate after the car has been slowed down. The error message can only be reset when the engine is switched off...


"VSA" stands for "Vehicle Stability Assist". This system has four indicators: The ABS indicator, the VSA indicator, the VSA activation indicator and the Brake System indicator.
When the system detects a malfunction, it illuminates the appropriate indicators. Depending on the failure, it determines which indicators to illuminate.
These lights illuminating do not necessarily indicate a failure in the VSA system itself. The VSA is only PART of the computer network in your vehicle. Information is shared among several control units. Certain malfunctions in the engine control or transmission control systems can cause the VSA to be disabled and the warning lamps will illuminate.
The only way to determine the cause of the problem with your vehicle is to perform a computer network scan to find out the nature of the failure and which control module requested the VSA to be disabled.

My vsa system indicator and vsa activation indicator light came on and it will not go off even when I turn off and on my honda- what does that mean?


It's hard to said what it is without a VSA code, but the VSA system monitor the rotation of you tires. Check and make sure you have the same tire size for all four tires. If the tires are not spinning at the same ratio could cause the VSA light to come. It could be a bad sensor or even the VSA modulator itself. It's hard to said. Good luck

2006 Honda crv, vsa, abs, and triangle light are permanently on


You are talking about the VSA activation indicator (triangle with exclamation point in the middle):
This indicator has three functions:

It comes on as a reminder that you have turned off the vehicle stability assist (VSA) system.

It flashes when VSA is active.

It comes on along with the VSA system indicator (the rectangle with VSA in it) if there is a problem with the VSA system.

This indicator normally comes on for a few seconds when you turn the ignition switch to the ON (II) position, and when the ignition switch is turned to the START (III) position.

Hope this helps you understand the problem.
