TIRE PRSSR CONTROL UNIT I7K3 or I7K4

[TopGun2000]

Any difference between them? either is about $340

The latest part # for I7K3 is 955 618 160 06

The latest part # for I7K4 is 955 618 160 13

After finding another nail in one of the tires, I am going to add TPMS for my 04 CTT just for peace of mind

I7K3 = Tire Pressure Monitoring, 433 MHz

I7K4 = Tire Pressure Monitoring, 315 MHz

[TopGun2000]

Thanks Loren. I assume the larger the part# is, the better quality/design the part should be

I guess I will just get the I7K4 with part# 955 618 160 13

The difference between 17K3 and 17K4 is the radio frequency ROW versus US 433/315 MHz.

[Loren]

Yes, RFM is correct 315 MHz is US frequency.

great, i will get the I7K4 set including the control unit, antenna, and sensors. :D

Does your 04 CTT have any prewiring installed from the factory for the TPMS or is this going to be a completely new installation?

i heard that there is an open connector where you can just plug in your control unit. you will probably need factory software, PST2 or PWIS to activate it.

i will check the wiring before i actually place the order.

I previously had made some enquiries at the dealers to do the exact same thing your planning.

They all said it could only be done at the factory and was too complicated to install after the car was built. (Apparently the antenna wiring from each wheel well has to be run to the control box etc.)

I hope you prove them wrong as I would like to retro install myself.

Good Luck. :thumbup:

April's Excellence has a good article on the TPMS.

I'd REALLY like to know if this is possible as well... Please post the result of your investigation. Thanks!

the installation should be fairly straightforward

1, the control unit is located under the dash near the foot brake

2, one antenna for each wheel under each wheel's housing liner (a little bit more work than the control unit)

3, ask a tire shop to install the wireless sender unit for all the wheels

4, ask a dealer to reprogram the control unit and related components

now just need to verify if the factory wiring exists for the control unit and antenna

total cost will probably be around $700 (assuming you can handle step 1 & 2)

If the prewiring is installed it would be a bonus for sure.

Hate to jump in late here but according to my literature the US frequency for the TPMS is 433 mhz.
