Volkswagen Sharan Training Manual – 2011 Electrics & Electronics

If you’re chasing an electrical gremlin in a 2011 Volkswagen Sharan, you don’t need aftermarket guesswork. I’ve been an ASE Master since ‘96 and I’ve watched techs burn three days on a wiring hunt because they used a diagram from a forum. This Training Manual is OEM Volkswagen material – 40 pages of design and function for the Sharan’s electrical and electronic systems. It won’t give you step-by-step repair instructions (that’s the service manual’s job), but it will show you exactly how the systems talk to each other. That’s what you need when a KESSY module won’t wake up or the RNS 315 goes dark.

Vehicle Electrical System and Networking Concept

This section lays out the networking architecture. The 2011 Sharan uses a CAN-bus system that links the convenience electronics, powertrain, and infotainment. Understanding the topology is critical before you start pulling fuses. The training manual diagrams show which control modules are on which bus – page references are in the TOC. You’ll save yourself a lot of backprobing by reading this first.

KESSY Keyless Entry and Start System (KESSY): What the Manual Teaches

The KESSY system controls door locking, unlocking, and engine start without touching the key fob. The manual walks through the transponder coil, the starter button logic, and the switching off procedure. If you’ve had a Sharan come in with a “Key Not Detected” message and you’re fighting the ESL (electronic steering column lock), you need the factory description. It explains how the ESL and KESSY interact – something the aftermarket wiring books always get wrong.

Does This Training Manual Cover Diagnostic Procedures?

Straight answer: no. This is a self-study programme, not a service manual. It describes function – so you understand why the system behaves a certain way. For diagnostics you’ll want the official workshop manual. But after you read this, you’ll know exactly which components to test and what signals to expect. Pair it with a proper scan tool and you’ll cut diagnosis time in half. If you’re a pro, you already know this. If you’re a DIYer, this is the missing piece that turns wiring diagrams into usable information.

RNS 315 and Aerial Systems – Factory Specs

This chapter covers the RNS 315 radio/navigation system, the aerial diversity system, and the UMPP mobile phone preparation. Page references for the RNS 315 map update procedure are in the Service section. You’ll also find details on the internal flash memory and how the system handles phone pairing. Don’t trust a third-party PDF for aerial part numbers – use the factory drawings here.

Service: Replacing the Electronic Steering Column Lock (ESL)

One of the most common failures on this generation Sharan is the ESL. The manual shows the correct replacement procedure – including the teach-in using the transponder coil. If you skip the teach-in you’ll have a steering column that won’t unlock. I’ve seen DIYers scrap the column because they didn’t follow the factory sequence. The manual also covers updating the RNS 315 software (requires a specific SD card format).

Why Factory Documentation Beats Aftermarket

Aftermarket manuals cut corners. They reuse diagrams from other models and guess at wire colors. This Volkswagen Sharan Training Manual was printed by the engineers who designed the car. The glossary even defines terms like “transponder coil” and “electrical steering column lock.” When you’re dealing with the engine start/stop logic on page 20, you want the real thing, not a copy.

Frequently Asked Questions

Is this the same as a service/repair manual?

No. This is a training manual (self-study programme) that explains system design and function. It is not a step-by-step repair guide with torque specs. Use it to understand how the electronics work before you touch the wiring.

Will this manual help me fix a KESSY module that won’t start the engine?

It will help you understand the KESSY communication flow and the role of the ESL transponder coil. The actual diagnostic steps need a workshop manual and scan tool, but without this knowledge you’ll waste time chasing wrong circuits.
