Hi,My name is Tim,
I will do my best to assist you
sense you get the 1570 and it wont clear
i would think your problem is the pcm[computer] itself
Thank Tim. I was not wanting to hear that but it makes sense. Are there any pins i can check for power or do you suggest plugging another ECM first.
i may have a pin out test
Could it be a not reading the key issue?
i wouldnt think the keyy sense the starter does turn the engine
you areloosing injector pulse,,right?
Yea.. im loosing the injector pulse. Spark stays
im trying to find a tests for you
i dont seem to have what you need

Section through cylinder plane engine 112, 113 12 Variable intake manifold 17 Fuel rail 19 Exhaust manifold, air gap insulated 22 Variable flap R4 Spark plugs (dual ignition) Y62 InjectorThe ME fuel injection and ignition system is a further development of the LH and DI and HFM systems, respectively. The abbreviated designation ME 1.0 means: M = Engine e = Electronics 1.0 = Version (further version e.g. 2.0, 2.1, 2.7, 2.7.1 or 2.8) The following functions are combined in the ME-SFI control unit: - Fuel injection - Ignition - Electronic accelerator with cruise control and idle speed control - DTC memory/diagnostic system, complying with EURO3/4 or OBD II for (USA) - Drive authorization system. Fuel injection system The fuel is injected by electromagnetic fuel injectors. These are actuated sequentially by the ME-SFI control unit, in other words an injector is assigned to each cylinder which meters the quantity of fuel computed for the cylinder. The air mass is the main measured quantity for determining fuel metering. It is detected through the hot film mass air flow sensor or through the boost pressure sensor (when charging). The ME control unit essentially analyzes the following information: - Coolant temperature - Air mass - Engine speed - Throttle valve position - Intake air temperature - Accelerator pedal position - The vehicle speed - Knock identification - O2-sensor signals - Ethanol share in fuel tank, only (USA) Flexible Fuel Vehicle (FFV). Idle speed control The idle speed is controlled by the throttle valve actuator, which is operated by the ME control unit, by altering the position of the throttle valve. Camshaft adjustment The inlet side camshaft of the engines 104, 111, 119 and 120 is adjusted on an electronic mapped basis by the ME-SFI control unit in the mid and upper engine speed and load range in order to boost the torque and power output.Engine 137 with one camshaft per cylinder bank also has camshaft adjustment. CAN data bus Dependent on year of construction, equipment and Model, control units are cross-linked via CAN. For example: - RCL control unit - ME control unit (Engine 120: left ME control unit and right ME control unit) - AT control unit - ABC control unit - SBC control unit - ETS/SPS [ETS/PML] control unit - ESP / SPS <ESP / PML control unit - ASR/SPS control unit - Instrument cluster - Electronic ignition switch. Electronic accelerator No mechanical link between accelerator pedal and throttle valve actuator. The pedal value sensor detects the accelerator pedal input for the ME-SFI control unit. Transmission upshift delay (only AT and TWC) The shift points of the automatic transmission are delayed in line with temperature, vehicle speed and time in order to more rapidly heat up the catalytic converter to its operating temperature. ENGINE 120 There are two independent fuel injection and ignition systems fitted. A separate ME control unit is installed for cylinder 1 to 6 (right cylinder bank) and for cylinder 7 to 12 (left cylinder bank). Ignition system The high voltage is distributed without the use of moving parts, directly by the ignition coils to the spark plugs (rotorless high voltage distribution). The anti-knock control (AKC) function is integrated in the ME-SFI control unit. Engine 119, 120: an ignition coil is positioned above each spark plug. Engine 111, 104: a twin spark ignition coil is installed for each two cylinders. Engine 112, 113: two spark plugs and a dual ignition coil are installed for each cylinder. Engine 137: alternating voltage ignition system with ignition module for right and left cylinder bank, dual ignition.
please stand by
one of the other guys may have more info on this
someone will be right with you
IM going to have a salvage yard bring a ECM tomorrow to plug in. Stand by
let me know what happens
Hey Marty.. sorry already at home thinking about this car as you can imagine..I did think that Ecm would be coded thanks.
The customer only got one key with car when purchased..
I have the proper Mercedes scanner and heard there is a way to go into DAS EZL to see if key is reading.? May be the module behind instrument cluster?
Thank you for getting back to me. I'll follow up with you in the AM if its ok.
Hey Marty.. sorry already at home thinking about this car as you can imagine..I did think that Ecm would be coded thanks. The more I think about it..sounds like a Key issue
goodmorning MArty. I agree need to get another key first. Just have to get the customer to understand the workings of her problem. Ill be doing so today and will be in touch as i go ..again thank you so much.
goodmorning MArty. I agree need to get another key first. I have checked all the fuses so. Just have to get the customer to understand the workings of her problem. Ill be doing so today and will be in touch as i go ..again thank you so much.
That was not a mistake. i believe in "giving to get" so you will get the same feedback if not better.
Marty..I have looked into replacing the DAS controller behind instrument cluster. Only to find out its @ 850.00 and the dealer will not sale the unit. I'm wondering if this could be the problem in addition to the key. Trying not to have to take to dealer but I'm also a bit shakey about ordering a key and the car still doesn't start. Im guessing either way I should still get another key first. What is your thought on it possibly being the DAS CONTROLLER?
No guts no glory Marty... I'm ordering now. Should be here Tuesday. Thanks for that reply. I'll be in touch when I get the key. You have a great day
Good afternoon Marty... so i have a new key here. Is there anything i need to do before cranking the engine. As far as synching? I notice that the key is not unlocking locking doors. Have not tried to start yey.
Yea.. still no start Marty.
Will do. I got a few other things going right now so I'll do it first thing in morning
Goodmorning Marty. So what am i looking for in the short test?
me1re p1570. Fault in DAS to Engine cont module. (will not erase)
EGS 114 sporadically selector lever imp[lausible
113 sporadic fault in entire CAN communication
RV-soft top bow a23/52 limit locked
ATA-drivers door actuator alarm triggered by door, by brake, by ignition, by trunk lid
AB srs airbag malfuntion indicator a1e15i
KLA- B1420 idle speed increase
B1422 serial interface k1 from instrument cluster to Ac cont. mod
B1416 heating water pump circulation pump
b1417 duo valve y21
cannot get into HFM ME2, ME RE, LH1, LH2, EZ1, EZ2, DM, EFP,TPM, GM..
hoping this is what youre looking for. Also this morning when i turn on the key the electric fans are now running?...
Marty just for grins i double checked fuel pressure and spark. the injector noid light may flash twice then stop..almost starts when it flashes. signal goes away
hey Marty i'll try when I get to the shop this morning. Back at you as soon as. May need to ask help navigating scanner. This is probably my last day with the vehicle as I'm sure the customer is not happy with me at this point. Maybe I'll figure it out today! Fingers crossed
Marty i need to learn when to let go. Im in it too deep to continue digging. Just smooged over the customer as best as i could. Ill be eating the key and labor. I appreciate you and your time on this matter.
I did. i wanna make sure that i gave you a good rating.
