Dear Forum Gurus...
my e320 1995
wagon is in limb home mode! The RPM are limited to 1500 rpms and it idles at 1000rpm! I know everybody would say wiring harness - NO it is not it was replace... Next would be the OVP... NO it is new also...
The next ones would say read the error code! Here we goo... (YES I cleared the old ones!)
PIN 8 shows...
- 8 Idle
speed control (ISC) system at upper or lower control stop or CC or EA indicates "limp
home" mode.
45 Fuel safety shut-off of electronic accelerator or
cruise control active
Pin 14 shows...
2 EA/CC/ISC control module (N4/1) or
Safety contact switch (M16/1s1) or Stop lamp
switch or Cruise control switch or Actual
value potentiometer or Starter lock-out/back-up
lamp switch or engine speed signal or
vehicle speed signal or closed throttle position
switch or safety relay in EA/CC/ISC control module
11 Closed throttle recognition signal to engine control module (HFM-SFI or Left LH-SFI)
Fuel safety shut-off to engine control module (HFM-SFI or left or right LH-SFI)
Now things get trickier! - Not knowing what to do I replaced the ETA! Mainly because in the manual there is a scenario described between a mismatch between the readings from the two potentiometers in the ETA if the cruise control is not activated...
HOWEVER I replaced the ETA and same story..
I will check the wiring next but what I noticed that the ETA seems to be operated at 5 V! This is highly unusual for a
car electronic and would it point to the unit itself being shoot?
Has anybody one of these units laying around in the Nashville area so I could check it? Obviously it has to work and come out of a running car!
OR anybody with a scan tool which can read the sub codes!
ANY other suggestions?
Cheers,...
