1995 W124 E320 wagon Check Engine codes 2, 6, 17
The "CHECK ENGINE" light illuminated on our 1995 E320 wagon with ASR (HFM electronics).
The vehicle has the 16-pole Diagnostic Connector with an LED.
I pulled the following number of blinks:
2, 6, and 17
I have two manuals for both analog and digital fault codes for the HFM M104 engine.
Which one do I use to decipher (analog or digital) ?
If analog:
2 = Engine coolant temp. sensor
6 = Not Used
17 = Injector, Cylinder
If digital, do I use the "OB15" or the "MB" key:
OB15
2 = engine coolant temperature sensor, open circuit
6 = hot film air mass sensor signal too high
17 = ISC (idle speed control) at upper control stop area, malfunction
MB
002 = engine coolant temperature sensor, short circuit
006 = intake air temperature sensor, short circuit
017 = throttle valve potentiometer drive value implausibly high
Thanks,
:-) neil
