Chevrolet HHR BCM clone by Karman Auto is a precise bench-programming workflow for the 2006-2011 Chevrolet HHR. 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.
Chevrolet HHR 2008-2011 BCM Clone Service — Overview
The Chevrolet HHR shares its BCM with the Cobalt and Pontiac G5 on the GM Delta platform, but the HHR adds retro styling features — panel-van variant (no rear windows), SS turbocharged 2.0L LNF with its unique boost-control coding, and a standard cargo management system that the BCM controls via dedicated body-style bytes.
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 Chevrolet HHR Owners Replace This BCM
HHR-specific BCM symptoms: panel version (cargo delivery variant) loses its unique door/window disable coding after a donor swap, SS turbocharged 2.0L exhibits “Engine Power Reduced” due to BCM-to-PCM handshake fault, rear hatch wiper runs continuously, and the retained accessory power timer (15 minutes on HHR vs 10 on Cobalt) reverts to wrong value. The classic “ignition switch recall” symptom — key rotating out of Run under knee pressure — is often misdiagnosed as BCM when it is the lock cylinder.
Platform & Technical Notes
Platform: GM Delta (shared with Cobalt, G5, Pursuit, Ion). Module supplier: Delphi E37-family. Chip: Freescale 68HC12. Communication: Class 2. Security: Passlock III. Programming tool: GM SPS/TIS2Web. HHR-specific body-style bytes and SS LNF handshake cannot be transferred by SPS alone — cloning is required to preserve HHR behavior on a donor.
Why Chevrolet HHR Owners Come to Us
Our HHR BCM clone carries over your exact configuration to the donor you supply: panel vs wagon body, LE5 2.4L vs LNF 2.0L turbo, manual vs automatic, standard vs SS trim, VIN, odometer, and Passlock III. Verified by re-read after the write.
Common Chevrolet HHR BCM Part Numbers
The BCM on the 2008-2011 Chevrolet HHR 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 2008-2011 Chevrolet HHR.
- 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
Add this Chevrolet HHR BCM clone service to your cart and complete checkout. Your receipt will include our shipping address. Ship us your marked original BCM plus a matching-part-number donor with the receipt enclosed. We clone, verify, and return both modules to you.

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 Chevrolet HHR (2008-2010) BCM module failure
HHR was built at Ramos Arizpe Assembly (Mexico) on the GM Delta platform shared with Cobalt. Distinctive 5-door retro wagon body has unique tailgate latch and cargo light circuits routed through the BCM. HHR Panel (commercial windowless variant) adds different rear-door coding. Common failure cause: water intrusion + internal capacitor aging on 2008-2009 first-batch HHR BCMs. Other: jump-start spikes, accident damage.
Chevrolet HHR (2008-2010) BCM clone — frequently asked questions
Can you clone a 2008-2010 Chevrolet HHR BCM?
Yes. Karman Auto clones every HHR BCM across LS, LT, SS, SS Turbo, and HHR Panel commercial variants for 2008-2010. 27 years of GM Delta-platform expertise.
Does the HHR SS Turbo use the same BCM as base HHR?
Same Delta platform hardware, different SS-specific software for boost gauge interaction. Clone preserves the SS Turbo coding exactly.
Can you clone the HHR Panel (commercial windowless variant) BCM?
Yes. HHR Panel has unique rear-door coding (no windows means no power-window relay activation). Clone preserves Panel-specific configuration exactly.
How long does the HHR BCM clone take?
24-48 hour bench turnaround. USPS Priority same day cloning is complete.
What fault codes indicate a failed HHR BCM?
B1325, B2960, U1000, U0140. DIC: “Service Theft System”.
What causes Chevrolet HHR BCM failure?
Water intrusion from windshield seal failure (Ramos Arizpe-Assembly HHRs are prone to this), internal capacitor aging on 2008-2009 boards, jump-start spikes.
Will my HHR keyless entry fobs work after the clone?
Yes. Fob pairing data preserved byte-for-byte.
Will OnStar work on HHR after BCM clone?
Yes (if equipped). VIN preserved means OnStar reactivates with original subscription.
Do I need a donor with exact same HHR part number?
Yes. Trim variants have different part numbers. Verify the white sticker.
Can you clone a water-damaged HHR BCM?
Yes. Water from windshield seals is a common HHR cause. EEPROM recovery at chip level.
Does the HHR cargo light circuit reset after BCM clone?
Yes. Cargo light timer is BCM-controlled. Clone restores operation.
Will my HHR rear hatch release work after BCM clone?
Yes. Rear hatch release command flows through the BCM. Clone preserves this exactly.
Does the BCM clone affect heated seat operation on HHR LT?
No. Heated seat control preserved in clone.
Is Chevrolet HHR BCM cloning legal?
Yes. Module cloning for repair is fully legal in all 50 states.
Why choose Karman Auto over a GM dealer for HHR BCM?
HHR was discontinued in 2011 with Delta platform retirement. Dealer Tech 2 reflash on used donor BCM costs $400-$800. Karman Auto clones for $249.
