SUBJECT:
Flash: Erroneous Tire Pressure Monitoring DTC's on Vehicles not Equipped With Tire Pressure Monitoring System
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Wireless Control Module (WCM) with new software.
MODELS:
2007 (PM) Caliber
NOTE:
This bulletin applies to vehicles built prior to February 16, 2006 (MDH 0216XX).
SYMPTOM/CONDITION:
The Wireless Control Module (WCM) may log diagnostic trouble code for the Tire Pressure Monitoring System (TPM) on vehicles that are not equipped with the Tire Pressure Monitoring System (TPM).
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, other than for the tire pressure monitoring system, 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� diagnostic scan tool fully supports Internet connectivity. However, in order to take advantage of this feature you must first configure the StarSCAN� 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".
