after rotate tires, reset TPMS?

[MikePhDPE]

i can't find my owner's manual. i rotated my tires, now the CEL came on and the trip meters, avg speed, average and inst mpg in the DIC all say "---". is there something i need to do to reset the TPMS?

Mike,

According to the manual the monitors have to be matched, including after rotation. Here is the process per the manual.

Greg

TPMS Matching Process for Vehicles
with Remote Keyless Entry (RKE)
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter’s LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner’s sensor is ready to be learned.
5. Remove the valve cap from the tire’s valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to
the tire/wheel position.
6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound
to indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS learn
mode, or if communication with the receiver stops, or
if the time limit has expired, turn the ignition switch to
LOCK/OFF and start over beginning with Step 2.

Also don't forget to re-torque your lug nuts after about 100 miles.

But before you move the vehicle, reset air pressure in each tire to proper inflation level (remember that you have either raised or lowered them all)

I prefer lowering the pressure and them adding air rather than raising and then lowering.

i tried this procedure and i could get to step 4 but step 5 would not work. it would not chirp and move to the next tire. i tried releasing air for just 8 seconds, i tried for much longer. every time it waits like sixty seconds, chirps twice and exits programming mode. i'll check the DIC and it will show the correct tire pressure but as LR instead of LF. after this i tore down my house looking for the manual and found it finally to check if my manual had the same procedure. it does.

i'm thinking it's just very finicky about how long the air is released, etc. any hints/tips??

thanks,
mike.

Mike, I believe the manual said you had two minutes to complete the process per wheel. If you took longer than two minutes the process will stop and you will have to start over. Not sure if this is causing your issue or not.

that's about right. the problem is that when i release or add pressure to the first wheel it won't chirp and move to the next wheel. now it's worse, the speedometer won't work.

There is no way for the Tire Pressure Monitor to know that you rotated your tires.

The "---" in TPM means that the system has lost it's memory.

With other functions effected, you have a problem with something. Not a Tire Pressure Monitor postition relearn issue.


What else besides rotate your tires did you do this weekend?

Off topic.......Small Dealer......love your avitar.......The Seven Ups is one of my favorite movies....When Scheider and one of his team break into Fester's house.....great scene!!....By the way, just found out that Roy Scheider died yesterday Feb. 10th....great actor.......sorry.....back on topic!

Thanks.

Had loaded up a bunch of pictures over the weekend for possible new avatars. One of them was The Seven-Ups with one of the Pontiacs used in the film. But with Roy's passing, substituted this one.

Oh, and Vincent Spano, James Garner and Burt Reynolds should see their doctors today.

i reset it and now the meters all read 0 instead of --. but the speedometer still doesn't work. and the inst mpg always reads 0 so i'm guessing it isn't reading the vehicle speed.

[MikePhDPE]

took it to the dealer. apparently when i changed the tranny fluid, i damaged a wire from the vehicle speed sensor. they "repaired the wire". now it all works. haven't tried resetting the TPMS yet, just got it back. there's now a rattle, i think when they put the exhaust back on they left it too close to a heat shield or something. i'll realign it tomorrow morning.

You changed the transmission fluid on your 08?

Dude; chill.

[MikePhDPE]

well it had 10k miles on it. i figured i'd change it when i changed the diff fluid.

Does this procedure need to be done any time the wheels are removed? Or only when rotating?
