SEAFETY PRECAUTIONS CRITICAL INFORMATION - READ THOROUGHLY An ECU could be damaged if an error occurs in the communication while reprogramming the ECU. Confirm all work is performed as described in these instructions. 1. STABILIZE THE POWER TO THE PERSONAL COMPUTER SIDE a) Be sure to connect the personal computer to an external AC power supply. NOTE: The ECU could be damaged if the battery voltage of the personal computer drops while reprogramming. b) Turn off the screen saver and power saving mode of the personal computer so that the power to the hard disk is kept supplied. NOTE: If the screen saver or power saving mode launches while reprogramming, the communication may be disconnected, resulting in the damage of the ECU. c) DO NOT block the ventilation opening for the cooling fan of the personal computer. NOTE: If the ventilation opening for the cooling fan is blocked with a sheet cover or the like, the personal computer may be heated excessively, causing the operation of the personal computer to stop. Due to the stop of the operation, the communication for reprogramming signals could be stopped, resulting in the damage of the ECU. V. CALIBRATION ID VERIFICATION 1. CHECK FOR DTC’S Using a Techstream, perform a Health Check to check for any Diagnostic Trouble Codes. NOTE: This Campaign covers only the software update to the DCM, as detailed in these instructions. It does not cover the diagnosis or replacement of any other systems on the vehicle. a) 2 2. CHECK CURRENT CALIBRATION a) Locate the Calibration column for the Telematics in the Stored Data tab for this vehicle. b) Check the Calibration ID of the Telematics ECU (DCM). Old Calibration FDC40.48.10 FDC40.58.10 Proceed to section VI. SHIPPING MODE VERIFICATION on p.4 Check the Calibration ID of the Telematics ECU (DCM). New Calibration FDC40.48.11 FDC40.58.11 Campaign complete. Return the vehicle to the customer. 3 VI. SHIPPING MODE VERIFICATION 1. Not in Shipping Mode Proceed to section VI. VEHICLE PREPARATION on p.4 a) CHECK TELEMATICS DATA LIST Select the “System Select” tab at the top left of the screen, select “Telematics” and click the right-arrow. b) Select “Data List.” c) Check to see if the Telematics Activation Status value is “Shipping.” Check to see if the vehicle is in Shipping Mode.

VEHICLE PREPERATION 1. a) CHECK DCM RECEIVING LEVEL Confirm that the DCM signal reception level shown in the upper right corner of the head unit display is not out of range. If the display shows poor or no connectivity, move the vehicle to another safe location with adequate signal reception. NOTE: • • 2. Refer to the image below for target signal reception. Full signal is not required but you must have at least one bar. VEHICLE PREPERATION a) Confirm the following conditions (Example): • Vehicle in the IG position (engine off). • Turn off all electrical accessories (i.e. air conditioning system, • Open the driver’s door window. audio system, etc.) • Transaxle in P range. • Hedadlight switch in the DRL OFF position.(w/ DRL OFF position) • Parking brake engaged. • Windshield wiper switch in the OFF position. NOTE: The electric fan does not operate during reprogramming, so stopping fan operation is unnecessary. b) 3. a) b) When the vehicle has no “off position” in the light control switch: 1) Turn the IG ON. 2) Set the light control switch to the AUTO position and make sure that the exterior lights are turned on. 3) Light up the automatic light control sensor with work light to keep the exterior lights turned off. CONNECT THE 12V BATTERY TO A POWER SUPPLY Connect the DCA-8000 battery charger to the 12V battery. Tap the Reflash icon from the Main Menu screen of the DCA-8000. A power supply MUST be used during reprogramming. ECU damage will occur if the battery voltage is not properly maintained during this re-flash procedure. NOTE: A power supply must be connected directly to the 12V battery terminals and NOT the remote jump posts under the hood (if equipped). 5 4. VERIFY TECHSTREAM SETUP a) Verify that the Techstream meets the following conditions: • The latest version of software is loaded. • The Techstream is connected to a 120V source. • The DLCIII cable is in good condition. The Techstream’s battery voltage must also be maintained during the re-flash procedure. Be sure to plug the Techstream into a 120V outlet during this procedure. VIII. UPDATE CALIBRATION Red Indicator Not Illuminated Not Illuminated 1. REPROGRAM CALIBRATION ID a) Confirm that the red indicator next to the SOS button is not illuminated. If the red indicator remains illuminated for longer than 2 seconds after IG-ON, there is a problem with the system that must be resolved before continuing.
