DeVille DTS V8-4.6L VIN 9 (2002)
This Service Procedure can be performed on Cadillacs or Oldsmobile.
1.
Prep the vehicle for Powertrain Control Module (PCM) reprogramming.
2.
Program the PCM using Techline Information System (TIS) data version # 2.0 or later, broadcast to dealers via GM Access on 2/10/03; or TIS #
2.0 or later CD-ROM mailing of 2/14/03. Refer to up-to-date Techline equipment user instructions.
3.
CALIFORNIA VEHICLES ONLY: Complete a "Proof of Correction Certificate" upon campaign completion.
4.
Install the GM Recall Identification Label.
Preferred Cadillac Reprogramming Procedure:
The following procedure should be used at dealerships supplied with the Kent-Moore J-45211 PCM wiring harness.
NOTICE:
It is critical that all J-45211 harness connections to the PCM, the Tech 2, and the power cable clips stay firmly connected throughout the entire
programming procedure. Failure to follow these instructions may cause interruption of the PCM programming, which may result in
PERMANENT DAMAGE to the PCM.
1.
Prep the vehicle for Powertrain Control Module (PCM) reprogramming.
2.
Check to ensure that both the Techline terminal and the Tech II are updated with their latest respective software. Use Techline Information System
(TIS) data version # 2.0 or later, broadcast to dealers via GM Access on 2/10/03; or TIS # 2.0 or later CD-ROM mailing of 2/14/03.
3.
Turn the vehicle ignition "OFF" and remove the key from the ignition lock cylinder. Turn off all electrical power consumers and accessories.
4.
Open the hood and check the battery voltage directly at the battery positive and negative terminals using J-39200 Digital Multimeter. If the
negative battery terminal is inaccessible, or the battery is not located underhood, check the voltage between engine block ground and the
underhood "+" junction block.
5.
If the vehicle's battery voltage is not 12.0 volts or higher, charge the battery before continuing. When finished charging the battery, disconnect the
charger from the battery before programming PCM.
6.
Locate the PCM and disconnect the vehicle harness connectors from the PCM.
7.
Connect the J-45211 harness connectors to the PCM.
8.
Connect the J-45211 power clips directly to the vehicle battery terminals. If the battery terminals are inaccessible, or the battery is not located
underhood, then connect to the engine block (ground), and to the underhood source of "B+" 12-volt power.
9.
Observe the red battery LED on J-45211. The red LED should remain lit whenever the J-45211 is connected to battery voltage. If the red LED
does not illuminate, check the tool's 5-amp fuse. If the fuse is okay and yet the red LED will not illuminate, contact Kent-Moore at
1-800-GM-TOOLS for assistance.
10.
Toggle the power switch on J-45211 to apply ignition voltage to the PCM.
11.
The yellow and green LED(s) should illuminate when the power switch is toggled on. The yellow LED monitors the ignition voltage being applied
to the control module. The green LED(s) are a feedback signal from the control module indicating that the module's internal circuits are operating.
12.
Connect the Tech II to J-45211 and enter Service Programming Systems (SPS).
13.
Select and perform Request Information.
14.
After the Tech II has completed the Information Request, toggle the J-45211 switch off.
15.
Turn off the Tech II and disconnect it from J-45211.
16.
Connect the Tech II to the Techline terminal. Download the new PCM calibration into the Tech II using the Techline Terminal and TIS 2000
software. After the download into the Tech 2 is complete, disconnect the Tech 2 from the Techline terminal.
17.
Reconnect Tech II to J-45211 and toggle the tool's power switch on.
18.
Enter Service Programming System (SPS), select and perform Program.
