Tire Monitor System - Sensor Programming Methods
NUMBER: 08-009-06GROUP: Vehicle Performance
DATE: February 17, 2006
THE StarSCAN(R) FLASH FILES FOR THIS BULLETIN ARE AVAILABLE VIA THE INTERNET.
THE FLASH FILE WILL BE AVAILABLE ON THE NEXT StarSCAN(R) UPDATE CD RECEIVED AFTER CD 6.05.
SUBJECT:
Tire Pressure Monitoring (1PM) Sensor Programming Methods
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Wireless Control Module (WCM) with software that provides an alternative tire pressure sensor programming option.
MODELS:
2007 (PM) Caliber
NOTE:
This bulletin applies to vehicles built prior to February 16, 2006 (MDH 0216XX).
SYMPTOM/CONDITION:
Anytime the WCM or a TPM pressure sensor is replaced, the WCM must learn the new TPM sensors ID's. The current and new TPM sensor learning process is outlined below:
NOTE:
It is recommended that the WCM be flashed so the new sensor learn process will be used
Current TPM Sensor Learning Process
^ The vehicle must sit at zero speed for 20 minutes or more before the TPM system can learn the new TPM sensors.
^ The TPM sensor learning process will start automatically once the vehicle speed reaches 25 MPH.
^ The vehicle speed must stay above 25 MPH continuously for a minimum of 10 minutes to complete the TPM sensor learning process.
If the TPM sensor learning process does not complete the TPM system will store a DTC in the WCM, C151C - Tire Pressure Sensor Missing after 10 minutes of driving. The TPM lamp will flash and dashes will replace the tire pressure information on the EVIC screen for the affected sensor.
New TPM Sensor Learning Process After Flash
The updated TPM sensor learning process is outlined below:
^ The vehicle must sit at zero speed for 20 minutes or more before the TPM system can learn the new TPM sensors.
^ The TPM sensor learning process will start automatically once the vehicle speed reaches 25 MPH.
^ The vehicle speed has been above 25MPH for a minimum of 10 minutes to complete the TPM sensor learning process.
The updated software will eliminate the need to stay above 25 MPH continuously, allowing for stop and go city driving.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with TechCONNECT and the appropriate Diagnostic Procedures, verify all systems are functioning as designed. If DTCs are present, record them on the repair order and repair as necessary before proceeding further with this bulletin.
NOTE:
There are two methods to download flash files to StarSCAN(R). The first (preferred) method is to download the flash files to the StarSCAN(R) from the internet. The second method is to download the flash files from the StarSCAN(R) Software Update CD.
SPECIAL TOOLS / EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, in order to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. For instruction on setting up your StarSCAN(R) for the dealer's network; refer to the StarSCAN(R) Quick Start Networking Guide available on the website under the "download center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Power ON the StarSCAN(R).
5. Retrieve the old WCM part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the appropriate ECU (WCM) in the list of modules.
c. Record the WCM "Part Number", displayed on the "ECU Overview" screen, for later reference.
6. Download the flash file from the internet to the StarSCAN(R). Using the StarSCAN(R) at the "ECU Overview" screen:
a. Select "More Options"
b. Select "ECU Flash".
c. Select "Browse for New File". Follow the on screen instructions.
d. Select "Download to Scantool".
e. Select "Close" after the download is complete, then select "Back".
f. Highlight the listed calibration.
g. Select "Update Controller".
h. When the WCM update is complete, select "OK".
NOTE:
Due to the WCM programming procedure, a DTC may be set in other modules (PCM, ECM, BCM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
REPAIR PROCEDURE - USING SOFTWARE UPDATE CD TO RETRIEVE THE FLASH FILE:
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
NOTE:
For detailed information on the operation of the StarSCAN(R), refer to the Quick Reference documentation provided in the StarSCAN(R) documentation kit. In addition, more recent information may also be available at the website. Look under "Training Aids" and also under "Download Center > Frequently Asked Questions" for more help.
1. Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.
2. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
3. Power ON the StarSCAN(R).
4. Retrieve the old WCM part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the appropriate ECU (WCM) in the list of modules.
c. Record the WCM "Part Number", displayed on the "ECU Overview" screen, for later reference.
5. Insert the StarSCAN(R) Software Update CD into the TechCONNECT or equivalent PC. The StarSCAN(R) Software Update CD will start automatically. Select "Download Flash Updates".
6. At the "Select a method for looking up controller flash updates." screen:
a. Select "Enter part number". Enter the WCM "Part Number" recorded in Step # 4 when prompted to do so.
b. Using the mouse highlight the appropriate "Calibration". Select "Next".
c. Follow the on screen instructions.
d. When completed, proceed to Step # 7.
7. With the StarSCAN(R) powered OFF, connect the USB Key and Gender Changer to the StarSCAN(R) USB port (Fig. 1).
8. Connect the StarSCAN(R) to the vehicle (if not already connected).
9. Power ON the StarSCAN(R).
10. Download the flash file from the USB key to the StarSCAN(R). Using the StarSCAN(R) at the "Home" screen:
a. Select "Flash Download", then select "Retrieve files from the USB storage device"
b. Highlight the appropriate calibration. Select "Download to Scan Tool"
c. When the download is complete, select "Close" and "Back".
11. Reprogram the WCM. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View".
b. Select "More Options".
c. Select "ECU Flash".
d. Highlight the appropriate calibration.
e. Select "Update Controller". Follow the on screen instructions.
f. When the WCM update is complete, select "OK".
NOTE:
Due to the WCM programming procedure, a DTC may be set in other modules (PCM, ECM, BCM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
