SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Suddenly it happens, your PHP page shows this message in red: "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data" and you don't know why.

Somewhere in your code, you were using curl and were playing with the headers. You must have inserted this command:

header('Content-Type: application/json'); 

To Fix this error: you need to insert this statement right after you are done with JSON.

header('Content-Type: text/html; charset=utf-8');

Mercedes Benz Diesel CDI EGR Emulator Circuit Diagrams

Mercedes EGR Emulator Circuits for Electric Wahler EGR on Diesel Engine For any car fitted with a MAF you can't just block the  EGR valve  as the MAF detects the reduced airflow when the valve operates. If it fails to report this reduction the ECU throws a code, turns on the MIL light and engages Limp Home mode. The  EGR valve  is operated in varying degrees whenever the engine is in cruise mode. A circuit has to be designed that reduces the MAF output voltage whenever the  EGR valve  is called to actuate. Having seen a mod on another forum I decided to give it a go and installed it last night. The circuit is really simple. The  EGR valve  transducer is fed with constant 12v which is proportionately shunted to Gnd to create the potential to activate the transducer, to engage the EGR solenoid and allow hot gasses into the intage via the  EGR valve  in varying degrees. The MAF is in the cold air intake. the EGR gasses enter further downstream. the MAF then monitors the red

Lots of these Messages about the Diagnostic Service Host in the System Log On Windows 7/10 Machines Attached to A Domain The Diagnostic Service Host service failed to start due to the following error: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration.  The good news is that you can fix it using active directory group policy or the Local Security Policy and just adding a few things to the Local Policies.  Same fix applies to both Windows 7 and Windows 10.  To Fix this using any Policy, you must be running a Professional or Enterprise version of Windows. If you have Home Edition, sorry. Here's How to Fix It You see this in your system logs repeatedly, and its dragging down your computer and making it run slow.
