Mercedes-Benz No Start No Crank? This Driver Display Message Is a Diagnostic Clue

"Take your key from ignition."

Most Mercedes-Benz owners ignore this message. Technicians shouldn't.

On DAS3-equipped Mercedes-Benz vehicles like the W204, this instrument cluster message confirms that the Electronic Ignition Switch (EIS) has successfully recognized and authenticated the remote key.

If the message appears, the key and EIS are communicating. If it doesn't, the EIS may not be recognizing the key, making this one of the quickest checks you can perform during a Mercedes no crank or no start diagnosis.

This video also shows how to confirm the result using iSCAN NX drive authorization data by monitoring:
• PID 9 – A Valid Key Was Detected
• PID 10 – Start Enable for Control Unit ESL Is Issued

Understanding these clues can help you narrow down Mercedes DAS3 faults before replacing expensive components.

Applicable to supported Mercedes-Benz DAS3 systems.

This video demonstrates how to program and commission a 4th generation FBS4 Mercedes Benz 722.9 VGS4 conductor plate using the iSCAN NX without requiring factory Xentry access or remote Support On Demand services.

Traditionally, programming a Mercedes 722.9 FBS4 conductor plate required OEM tools and theft authorization procedures through the factory system. Using the iSCAN NX together with the EM-C1 Y cable and MB-V4N2-C1 transmission component cable, technicians can now perform ECU cloning and programming in-house on supported applications.

The process uses a simultaneous connection to both the vehicle and the original transmission control unit. The original VGS4 conductor plate remains installed during the initial read and data transfer process while information is cloned to the replacement ECU. Once the transfer is complete, the replacement conductor plate can be installed and final commissioning procedures performed.

This workflow is especially valuable for shops replacing Mercedes 722.9 conductor plates, programming used donor transmission control units, or performing FBS4 transmission repairs without relying on dealer-level tooling.

The video also covers important setup and programming considerations including:

Proper use of the EM-C1 Y cable
MB-V4N2-C1 transmission connection cable setup
Stable power supply requirements
Wired communication between NX and VCI
ISM considerations when using donor transmission assemblies
Final adaptation and selected gear teach-in procedures

The ability to directly clone and commission Mercedes transmission ECUs using dedicated component cables and OE-level workflows is one of the advanced programming features available with iSCAN NX.

Land Rover Electronic Parking Brake EPB Frozen Brake Caliper Releasing | L460

Land Rover L460 models are equipped with an electronic parking brake (EPB) system. An electric actuator works in conjunction with the rear brake caliper to clamp the rear brake pads when the parking brake is applied.

A vehicle with a faulty EPB actuator or frozen caliper will prohibit your ability to enter parking brake service mode. In that situation, you can manually release the caliper to perform maintenance or repair.

Keep in mind, when replacing an EPB actuator or caliper, you will first enter ABS assembly mode. See our video on ABS assembly mode.

In this video we will provide an overview of the process on one side of the vehicle. In the event of a vehicle with no electrical power, you will need to perform this on both sides.

When complete, be sure to enable assembly and perform an EPB calibration using your iSCAN device.

Fault Code Testing 48 Volt Integrated Starter Alternator (ISA) Mercedes-Benz Mild hybrid

In this video we’re going to illustrate how to test the integrated starter alternator or ISA used by Mercedes-Benz 48 volt mild-hybrid vehicles.

The ISA has 3-phase windings with 18 coils, one side for the starter and one for the alternator. You’ll need to perform this test when a fault code is stored to either condemn or rule out the ISA as the cause.

Common fault codes for Electric Machine A or Electric Machine B N179 ISA:
P0A6400 The current value of phase W of electric machine A is too low.
P0C1900 The torque of electric machine A deviates from the specified value

You’ll need a four-way milli-ohm test meter, like this Gossen MetraHit or the Mercedes-Benz approved Hioki meter.

In this test, we will test each leg of the ISA to check resistance in the milli-ohm range.

Test specs for each leg of the ISA:
Phases U to V, then V-W and then W - U: 9.1 milli-ohm plus or minus 0.3
Phases X - Y, then Y - Z and then Z - X: 8.7 milli-ohm or minus 0.3

If any of these values are out of spec, the ISA is faulty and will need to be replaced.

What iSCAN NX Can Do That Xentry Won’t - Fix Mercedes Coding Mismatch Problems

Many Mercedes Benz technicians are familiar with the limitations built into the factory Xentry workflow. Certain programming paths, module replacements, and recovery procedures are restricted by factory guardrails that can limit repair options in the aftermarket.

This video highlights how iSCAN NX gives technicians more flexibility when working with Mercedes Benz control modules, coding, and programming functions.

With iSCAN NX, technicians can perform advanced in-device operations including:

Individual module coding
Used module overwrite procedures
Module recovery using original ECU data
Coding mismatch correction
Data transfer between donor and replacement modules
Advanced Mercedes ECU programming workflows

One example shown in this video involves a Mercedes ETC transmission control module with a no communication condition. Using a working donor module, data can be read and transferred to a replacement module, allowing the technician to recover important transmission and shift data during the commissioning process.

These types of advanced recovery functions can help shops solve problems that are difficult or impossible through standard factory workflows alone.

For independent repair facilities working on Mercedes Benz vehicles, having access to flexible OE-level programming and coding functions can mean the difference between replacing additional components, sending the vehicle to the dealer, or completing the repair in-house.

This video demonstrates how iSCAN NX can be used as a practical solution for Mercedes module recovery, transmission ECU replacement, and advanced coding situations.

Mercedes Benz Power Tailgate One Touch Failure Solution

If the one touch power liftgate button stops working on a Mercedes Benz vehicle, the problem may not be the latch, switch, or liftgate motor. In many cases, the issue is related to outdated SCN coding or a software update identified in a factory technical service bulletin.

This video explains how a liftgate operation problem can often be corrected by checking for applicable Mercedes Benz TSB information and performing an SCN coding update using the native coding and programming capabilities built into the iSCAN NX.

On certain Mercedes platforms, updated software calibration is required to restore proper one touch liftgate operation. After the SCN coding process is complete, the liftgate system must also be normalized so the control module can relearn the tailgate operating limits and positions.

The video demonstrates the normalization process and explains why this final step is important after programming or coding updates are performed.
This type of issue highlights how many modern Mercedes Benz convenience system faults are software related rather than mechanical failures. Having access to OE-level coding and programming functions allows shops to diagnose and repair these problems quickly in-house without unnecessary parts replacement.

If you are diagnosing a Mercedes Benz power liftgate problem, one touch tailgate malfunction, or intermittent trunk operation issue, checking for coding updates and normalization requirements should be part of your diagnostic process.

M256 Engine - Misfire Fault P035596 Do Not Replace Coils Before Checking This

This video covers an important diagnostic warning for Mercedes Benz M256 engines showing fault code P035596, commonly associated with a cylinder 5 ignition or misfire fault.

Many technicians see this fault and immediately replace ignition coils and spark plugs. While those components can fail, another growing issue on M256 engines is degradation of the engine wiring harness near the ignition system.

Heat exposure, tight harness routing, and repeated thermal cycling can cause the wiring insulation to become brittle and crack, especially near ignition coil connectors and areas where the harness flexes. In some cases, simply moving the harness during spark plug or coil replacement can expose damaged insulation or aggravate an existing short.

If the damaged wiring shorts internally or to ground, the result may not only be a recurring misfire, but possible damage to the ME engine control module itself.

This video explains where to inspect the harness, common areas where insulation failure appears, and why identifying the root cause before replacing ignition components can prevent expensive repeat failures and unnecessary module replacement.

When diagnosing P035596 or other M256 cylinder-specific ignition faults, always inspect:

Coil connector wiring
Harness bends and stress points
Heat affected sections near the exhaust and turbocharger
Cracked, brittle, or shedding insulation
Signs of previous harness movement or repair

Catching harness degradation early can save the customer significant cost and prevent a simple misfire diagnosis from turning into a major engine electronics repair.
