Pontiac Grand Prix 2004-2009 BCM Clone Service — Body Control Module Bench Programming
$249.00
Professional Pontiac Grand Prix 2004-2008 BCM cloning service. Clone service only — customer supplies original (marked “OLD”) plus a donor with the matching part number. We perform a byte-for-byte 1:1 data transfer and verify by re-reading the donor. Both modules returned to you. 24-48 hour turnaround.
Pontiac Grand Prix BCM clone by Karman Auto is a precise bench-programming workflow for the 2004-2008 Pontiac Grand Prix. Specifically, we read your original failed module, write the data byte-for-byte onto a donor you supply, and then verify the copy before shipping both back. Moreover, your VIN, immobilizer seed, and factory trim coding are preserved exactly. However, you are responsible for sourcing a donor that carries the identical factory part number — we do not sell or swap modules.
Pontiac Grand Prix 2004-2008 BCM Clone Service — Overview
The seventh-generation Pontiac Grand Prix (including the GXP with its 5.3L LS4 V8) is a W-body sedan built at GM’s Fairfax Assembly. Its BCM uniquely coordinates the Grand Prix’s “Driver Information System” with heads-up display on GT and GXP trims, plus the StabiliTrak module and its unique magnetic-selective-ride (GXP) chassis code.
What This Service Is (And Is Not)
This is a cloning service only. Karman Auto does not sell parts or donor modules. You ship us two BCMs: your original (failed) unit and a donor unit you have sourced with the exact same part number. We read the data from your original, write it byte-for-byte onto your donor, re-read the donor to verify the copy, and ship both modules back to you. The donor becomes a functional replacement for your original.
Common Reasons Pontiac Grand Prix Owners Replace This BCM
Grand Prix BCM failure symptoms: HUD that will not illuminate or displays wrong data, StabiliTrak lamp that will not clear, trunk-release from the key fob that stops working, passenger sensing mat error, and the GXP-specific magnetic ride DTC C0561 which actually originates in the BCM on this platform. Many 2004-2005 units also lose the driver-door unlock pulse after a BCM brownout.
Platform & Technical Notes
Platform: GM W-body. Module supplier: Delphi. Communication: Class 2 serial data. Security: Passlock III. Programming tool: GM SPS/TIS2Web. The Grand Prix GXP’s LS4 V8 requires specific BCM-to-PCM handshake coding that cannot be copied from a Grand Prix GT donor, so LS4 owners in particular benefit from cloning over simple donor swap.
Why Pontiac Grand Prix Owners Come to Us
We clone the exact Grand Prix configuration — GT vs GXP, coupe vs sedan, HUD-equipped vs not, sunroof equipped vs not — along with VIN, odometer, Passlock III seed, and the LS4 handshake if applicable.
Common Pontiac Grand Prix BCM Part Numbers
The BCM on the 2004-2008 Pontiac Grand Prix is commonly seen in the following part numbers. Your exact part number must match the donor you supply — mixing part numbers will not work even within the same platform family. Check the label on your original BCM before sourcing a donor.

This is a common-numbers reference. If your original carries a number not on this list, that is fine — the requirement is simply that your donor carries the same number as your original.
Shipping Instructions
After you complete checkout, your order receipt will include the shipping address for Karman Auto. Please follow these steps:
- Remove your failed BCM from the vehicle following the factory service information for your 2004-2008 Pontiac Grand Prix.
- Source a donor BCM with the exact same part number as your original. We cannot substitute part numbers.
- Mark the original module “OLD” clearly with tape, a sticker, or a permanent marker. This tells us which module to read the data from.
- Print your order receipt and enclose it in the shipping box — the receipt contains the return address we will use to ship both modules back to you.
- Pack both modules (original + donor) in anti-static bubble wrap inside a sturdy box. Ship to the address shown on your receipt.
Turnaround
Typical bench time is 24-48 hours from the moment both modules arrive at our shop. Rush service is available on request — contact us before you ship.
How to Order

Warranty
1:1 Data Transfer Guarantee
Karman Auto guarantees a byte-for-byte 1:1 data transfer from your original BCM onto your supplied donor. We read the original, write the donor, and re-read the donor to verify the copy before shipping. This is the only warranty we offer. We do not warranty the donor hardware, installation, wiring, or any unrelated vehicle issue. You are responsible for sourcing a functional donor with the matching part number.

What causes Pontiac Grand Prix (2004-2009) BCM module failure
Pontiac Grand Prix on the W-body platform was built at Fairfax Assembly. The 7th-gen Grand Prix (2004-2008) shares the BCM with Buick LaCrosse/Allure. Common failure cause: water intrusion from windshield seal on 2004-2006 first-batch W-body BCMs. Internal capacitor aging is well-documented. Grand Prix GXP variant with the 5.3L V8 LS4 adds underhood thermal stress. Other causes: jump-start spikes, alternator regulator failure, accident damage.

Same W-body hardware, different software for the LS4 V8 transverse engine’s unique cooling fan logic. Clone preserves GXP coding exactly.
Does the GTP supercharged variant clone differently?
No, same bench process. Different software flags for supercharger intercooler fan logic preserved in the clone.
How long does the Pontiac Grand Prix BCM clone take?
24-48 hour bench turnaround.
What fault codes indicate a failed Grand Prix BCM?

Will my Grand Prix HUD work after BCM clone (if equipped)?
Yes. HUD intensity and content coding lives in the BCM. Clone preserves it exactly.
Will my Grand Prix keyless entry fobs work after the clone?
Yes. Fob pairing data preserved byte-for-byte.
Do I need a donor with exact same Grand Prix part number?
Yes. Trim variants have different part numbers. Verify the white sticker.
Can the Grand Prix BCM be cloned from a Buick LaCrosse BCM?
No. Same W-body hardware but different brand-specific coding. Pontiac BCM cannot be sourced from Buick. Donor must be a Grand Prix.
Can you clone a water-damaged Grand Prix BCM?
Yes. EEPROM recovery at chip level.
Does OnStar work on Grand Prix after BCM clone?
Yes (if equipped). VIN preserved means OnStar reactivates with original subscription.
