Bosch 147, 156, 159, 166, 2400 2011 Technical Manual

If you work on bikes with Magnet Marelli ECUs – specifically the 5AM and 5SM units found on early 2000s Ducatis and Moto Guzzis – you’ve been stuck with an immobilizer that won’t talk. The ECU sees a key code mismatch, the engine cranks but won’t fire, and you’re guessing which wire to jump. That guessing stops the second you open this Bosch 147, 156, 159, 166, 2400 2011 Technical Manual. It’s the factory document for the diagnostic tools that handle IMM/CONFIG E2P utility functions. 48 pages, straight from Bosch’s 2011 release.

The manual doesn’t waste space with theory. Page one kicks off with a table listing every Ducati model that uses the 5AM or 5SM ECUs – from the 996 Desmoquattro all the way to the 1198S. Next column: which ECU version, and what the IMM & CONFIG ERASE function does. Same for Moto Guzzi vehicles. If you’ve ever swapped an ECU into a Monster 1000 without clearing the immobilizer memory, you know the bike won’t start. This manual walks you through the exact procedure to reset that data without bricking the module.

IMM/CONFIG E2P Utility Functions – Why This Matters

Most aftermarket scan tools give you a generic ‘erase immobilizer’ button that either does nothing or locks the ECU forever. Bosch’s own manual – for the 147, 156, 159, 166, and 2400 tool platforms – specifies which vehicles support the function, what the software version must be (list updated PM22:34 08/11/2011), and how to confirm the erase completed. No guesswork. You pick the vehicle from the list, confirm the ECU brand and version, then run the function. If the tool says ‘done’, the bike starts. If it doesn’t, you know you have a hardware problem, not a software problem.

Does This Manual Cover Your Bike?

Check the tables. The manual lists every Ducati Multistrada from 620 to 1100, every Monster from 620 to S4R S, the SportClassic GT 1000, the SportTouring ST3 and ST4S, the Streetfighter 1099, and all Superbikes from 749R to 1198S. If you’ve got a Moto Guzzi with a 5AM ECU (like the Griso 1100 or Breva 1200), that’s in there too. The list is focused on vehicles that used Magnet Marelli ECUs between 2001 and 2011. Older bikes with Siemens or Marelli IAW 59M aren’t covered – you’d need a different Bosch manual for those. But if your Ducati or Guzzi has a 5AM or 5SM, this is the only manual that tells you exactly how to unlock the ECU after an immobilizer lockout.

3 Steps to Use the Config Erase Function Safely

First: connect your Bosch tool (147, 156, 159, 166, or 2400) to the diagnostic port. Second: navigate to the IMM/CONFIG menu. Third: select the exact vehicle model from the list – don’t guess based on engine size, the manual uses the exact model year and ECU version. For example, the 2008 Hyperstrada 1100 and the 2006 Hyperstrada 1100 use the same ECU but the software version differs. Pick wrong, and you risk corrupting the E2P. The manual’s table includes model years where needed, so you match the VIN to the entry. Only then run the erase function. After the tool confirms success, cycle the ignition and start the bike. If it fires, you’re done. If not, verify the key transponder and antenna ring – this manual doesn’t cover those, but it tells you the function worked.

Get the Right Diagnostic Procedure

Don’t rely on forum thread that says ‘jump pin 4 to ground’. That’s how you fry an ECU. Bosch’s own procedure uses the tool’s dedicated CAN or K-line communication – the manual specifies which protocol each model uses. The 5AM ECUs communicate on K-line, the 5SM on CAN. Hook up your tool wrong, and the immobilizer stays locked. This manual gives you the pinout reference and the required tool firmware version. You’ll also find a list of Bosch Vehicle Component Applications Index D1 that cross-references ECU brands with Bosch tool compatibility. If you’re working on a 2010 Ducati 848 EVO, the manual tells you the ECU is a 5AM and the tool needs firmware version XX (table lists it). After that, you can navigate to the CONFIG E2P section and pull the immobilizer code or erase it. Same for Moto Guzzi – the OCR shows the beginning of a Guzzi table, so expect that section in the PDF.

For the home garage guy: this manual isn’t for rebuilding engines. It’s for fixing electronics that keep the engine from starting. If you own a Ducati and swapped the ECU, or you bought a wrecked bike with a locked immobilizer, this is the cheapest way to get it running without paying a dealer $200 to press a button. The manual expects you to own a Bosch diagnostic tool (147,156,159,166, or 2400). If you don’t have one, you’ll need to buy or borrow one – but the manual itself is the key to using it correctly.

Source Authenticity: OEM Bosch vs. Aftermarket Copies

This isn’t a scanned copy of a photocopy. It’s the original 2011 PDF from Bosch – 48 pages, clean text, no OCR errors. I’ve seen aftermarket versions that blur the voltage specs or miss a column in the vehicle list. This one has the full table with all Ducati models, including the 2008 and 2009 variants that later aftermarket docs dropped. The PDF includes the original Bosch watermark and the file date: 08/11/2011. When you’re dealing with ECU reprogramming, one wrong bit can cost you a $500 module. OEM documentation is the only thing I’ll trust under the hood. Aftermarket manuals? I’ve seen torque specs listed in Nm that were actually foot-pounds – never again. Stick with the factory prints.

Related manuals worth having: Bosch NG6, NG10 Technical Manual – 204 Pages of Factory Hydraulic Specs and Bosch KTS 550 2004 Technical Manual – Factory Specs. Both cover different aspects of Bosch diagnostics. For general transmission work, see the Manual Transmission section on Wikipedia, and for older vehicle ECUs, check the Manual Transmission basics – but those are no substitute for the factory Bosch procedure.

Q: Is this manual for the Bosch 147 diagnostic tool or the machine tool?

The models 147, 156, 159, 166, and 2400 refer to Bosch diagnostic platforms (KTS series) used for vehicle electronics. This manual covers the IMM/CONFIG E2P utility function for those tool versions when working on Magnet Marelli ECUs.

Q: Does it cover the Bosch 2400 tool?

Yes.

Q: Can I use this manual to reprogram the ECU on a 2006 Ducati Multistrada 1000 DS?

Immobilizer erase only. The manual covers the IMM & CONFIG erase function, not full ECU remapping. For the 2003-2006 Multistrada 1000 DS with IAW 5AM ECU, the manual lists the exact procedure to clear the immobilizer memory. You’ll need a different Bosch manual for power tuning. The vehicle list includes that model with year (2003) in parentheses – always check the year column when selecting in the tool.

Q: Is the manual available in hard copy or only PDF?

Digital access only from AutoRepairManuals. The PDF is searchable, printable, and watermarked. 48 pages, 2011 release. You can view it on a tablet or print the relevant pages for the bay. I keep mine on a ruggedized laptop so grease doesn’t destroy it.

Don’t waste time chasing immobilizer ghosts. Get the factory document that tells you exactly which bikes, which ECUs, and which tool firmware work. This manual will save you from buying a new ECU because you guessed wrong. Access the Factory Manual now and put it in your diagnostic folder. You’ll reference it the next time a Ducati or Moto Guzzi rolls in with a no-start and a flashing immobilizer light.
