Mx13 Ecm Pinout

By | September 11, 2023

The MX13 ECM pinout is a critical reference for anyone working on or servicing a Mercedes-Benz MX13 engine. This article will provide a detailed overview of the MX13 ECM pinout, including information on the location of each pin, the function of each pin, and the wiring harness that connects to the ECM.

MX13 ECM Pinout Overview

The MX13 ECM is located on the left side of the engine, behind the intake manifold. The ECM is a black, rectangular module with a number of pins on the bottom. The pinout for the MX13 ECM is shown in the following table. | Pin Number | Description | |---|---| | 1 | Ground | | 2 | +12 V Battery | | 3 | CAN High | | 4 | CAN Low | | 5 | LIN | | 6 | K-Line | | 7 | M-Line | | 8 | Accelerator Pedal Position Sensor (APPS) | | 9 | Engine Coolant Temperature Sensor (ECT) | | 10 | Intake Air Temperature Sensor (IAT) | | 11 | Mass Air Flow Sensor (MAF) | | 12 | Manifold Absolute Pressure Sensor (MAP) | | 13 | Camshaft Position Sensor (CMP) | | 14 | Crankshaft Position Sensor (CKP) | | 15 | Knock Sensor (KS) | | 16 | Oil Pressure Sensor (OPS) | | 17 | Fuel Level Sensor (FLS) | | 18 | Transmission Gear Position Sensor (TGS) | | 19 | Auxiliary Input 1 | | 20 | Auxiliary Input 2 | | 21 | Auxiliary Input 3 | | 22 | Auxiliary Input 4 | | 23 | Auxiliary Output 1 | | 24 | Auxiliary Output 2 | | 25 | Auxiliary Output 3 | | 26 | Auxiliary Output 4 |

MX13 ECM Wiring Harness

The MX13 ECM is connected to the vehicle's wiring harness by a 30-pin connector. The connector is located on the bottom of the ECM. The following table provides a list of the wires in the MX13 ECM wiring harness, along with their color and function. | Wire Color | Function | |---|---| | Black | Ground | | Red | +12 V Battery | | Yellow | CAN High | | Green | CAN Low | | Blue | LIN | | White | K-Line | | Orange | M-Line | | Brown | Accelerator Pedal Position Sensor (APPS) | | Gray | Engine Coolant Temperature Sensor (ECT) | | Pink | Intake Air Temperature Sensor (IAT) | | Violet | Mass Air Flow Sensor (MAF) | | Tan | Manifold Absolute Pressure Sensor (MAP) | | Light Blue | Camshaft Position Sensor (CMP) | | Yellow Green | Crankshaft Position Sensor (CKP) | | Dark Green | Knock Sensor (KS) | | Orange Red | Oil Pressure Sensor (OPS) | | Brown Black | Fuel Level Sensor (FLS) | | Light Green Black | Transmission Gear Position Sensor (TGS) | | White Black | Auxiliary Input 1 | | Orange Black | Auxiliary Input 2 | | Violet Black | Auxiliary Input 3 | | Tan Black | Auxiliary Input 4 | | Light Blue Black | Auxiliary Output 1 | | Yellow Green Black | Auxiliary Output 2 | | Dark Green Black | Auxiliary Output 3 | | Orange Red Black | Auxiliary Output 4 |

How to Read the MX13 ECM Pinout

The MX13 ECM pinout can be used to troubleshoot problems with the engine control system. To read the pinout, first identify the connector that is connected to the ECM. The connector will have a number of pins, each of which is labeled with a number. The pinout table can then be used to identify the function of each pin. For example, if you are troubleshooting a problem with the engine coolant temperature sensor, you would look for the pin in the pinout table that is labeled "ECT". The pinout table will tell you that the ECT sensor is connected to pin 9. You can then use this information to trace the wiring harness from the ECM to the ECT sensor. By understanding the MX13 ECM pinout, you can quickly and easily troubleshoot problems with the engine control system.
