Spn 523613 fmi 2 error cause

How to diagnose

Diagnostics includes collecting signs of problems in the system, scanning the electronic control system, resetting and checking all mechanisms and systems for faults in the electronic unit, inspecting all sensors that are responsible for the uninterrupted operation of the power unit.

During diagnostics of KamAZ-5490, 54115, 5308 and other models with an engine manufactured according to the international environmental standards Euro-3 and 4, the pressure level in the fuel system is measured, the performance of the generator set is tested and exhaust gases are analyzed using special equipment. They also check the winding of the electromagnetic regulator of the fuel supply system and the short circuit in the inductive sensor coils.

Equipment and programs for diagnostics

There are several scanners for detecting problems in vehicle mechanisms, for example:

1. Autoscanner DK-5. This equipment helps detect problems in the electronic unit by reading and adjusting control system indicators using a computer. This autoscanner can be used at temperatures up to +30°C and relative humidity no more than 80%.
2. Scanner EDS-24. This is a software and hardware complex designed for computer diagnostics of a cargo vehicle. It includes a USB adapter with galvanic isolation, which makes it possible to test systems in low voltage conditions.

How to reset errors

Resetting on KamAZ-4334, 5308 and other models can be done as follows:

1. Warm up the engine to operating temperature.
2. Remove the positive terminal from the battery for 5-15 minutes.
3. Connect the terminal back to the battery.
4. Turn the ignition key to the last position before starting the engine from the starter. In this case, the lights and indicators located on the dashboard should light up.
5. Leave the key in this position for 1 minute.
6. Return the ignition key to its original position.

If this does not help, then a short circuit should be made in the vehicle circuit. In this case, after resetting, you will have to replace the safety element.

How to diagnose faults on a KAMAZ truck?

Is a serious vehicle exhibiting inappropriate behavior? The vagaries of your truck can ruin business deals and lead to long periods of downtime, draining your wallet. In this article, we will tell you how to diagnose problems at an early stage in order to begin troubleshooting problems in a timely manner.

Recently, engines from the Kama Automobile Plant began to be classified according to their belonging to one or another environmental class (from Euro-0 to Euro-4). The technical implementation of the Euro-3 class, and then Euro-4, adopted in 2013, turned out to be impossible without the use of electronic engine control systems (ECM). This is what led to the opportunity to perform self-diagnosis of the car using KAMAZ universal error codes.

Ecological class Euro-4

Various configurations of KAMAZ trucks began to be equipped with engines with electronic control units (ECU). And if now the driver is concerned about unhealthy behavior during the operation of famous trucks, symptoms appear in the form of floating speed, loss of traction, unusual noises, increased diesel fuel consumption, self-diagnosis comes to the rescue.

Using information output from the ECU in the form of an error code, it is possible to indicate an accurate electrical diagnosis for KAMAZ. The process of diagnosing and deciphering codes depends on the type of electronic system installed on the truck. Before starting diagnostics, it is suggested to determine the type of ECU based on the installed engine model.

Engine Model Table

Self-Diagnostics No matter what company your V8 is made by, Cummins Inc. (Cummins) or KAMAZ LLC, it is equipped with fuel supply systems from Common Rail and exhaust gas recirculation (EGR) or neutralization systems (SCR), diagnostics will be carried out in accordance with these two types.

Engine with ECU BOSCH MS 6.1

So, let’s get comfortable in the cabin of our KAMAZ, then turn on the ignition with the usual turn of the key. Along with many other indicators, the diagnostic indicator light or “Check Engine”, or in common parlance, a submarine, lights up. The lamp lights up for 3 seconds and goes out, thereby demonstrating its functionality and the serviceability of the ECM. If the lamp does not go out or lights up while the engine is running, a malfunction has been found in the electronic system!

Diagnostic indicator lamp

Let's pay attention to the diagnostic mode rocker button (often mounted on the instrument panel on the left, under the steering wheel) or the button for this mode (often located next to the fuse box, under the panel opposite the passenger seat). The “rocker” has two extreme positions for holding and a central fixed position.

Diagnostic mode rocker button Diagnostic mode button

Lower the rocker to its highest or lowest position and hold it there for more than two seconds. Just press the button and do not release it for the above-mentioned time. After the rocker or button returns back, the diagnostic lamp will flash first in long intervals and then in short ones. The number of long flashes determines the first digit of the error code, the number of short flashes determines the second digit.

Blink Code Alarm Diagram

The diagram shows an example of obtaining code 24. We compare the error code (otherwise blink code, from the English blink - blink) with the table below.

There are often cases when the ECU has recorded several errors; to view the following code, repeat the above steps with the button or rocker. Error codes will be played cyclically. No more than five faults are recorded in the ECU memory. To delete all errors from the control unit’s memory, you must turn on the ignition and hold the “rocker” for five seconds. Thus, you can briefly rid your car of disturbing symptoms in the form of electronic restrictions.

Engine with ECU ISB CM2150

This type of ECU was installed on later KAMAZ models and the diagnostics in this case will differ from the above diagram. After turning on the ignition, the currently active fault is recorded in the memory of the electronic unit; in addition, the fault can be signaled by a red or yellow diagnostic control lamp.

Yellow and red diagnostic indicator lamps

After pressing the “rocker” in any extreme position for more than two seconds, a fault code will be displayed with a half-second interval between flashes of one of the two lamps. The error code digits are separated by a 2-second pause. Unlike the previous type of ECU, the resulting code will be three or four digits!

We compare the error code with the table below. The color of the rows in the table is correlated with the color of the diagnostic control lamp. The red color of the indication indicates the impossibility of starting or continuing driving with this malfunction; the yellow color indicates the need to eliminate the malfunction after finishing driving the vehicle.

If you do not find your engine brand or error code for the ISB CM2150 ECU in the table, be sure to write to us and we will immediately try to help.

The process of self-diagnosis of KAMAZ electronic systems in Euro-3, -4 engines differs slightly from a similar procedure in other vehicles. After pressing a certain button, one of the lamps on the dashboard or indicator unit will begin to blink at different intervals; the number of flashes of the lamp at one interval determines the digit of the code.

Video “Getting Error Codes”

The video shows an example of receiving error codes 36 and 37.

Hello! Your question has been sent to electronics specialists. Here is the answer: “The error code reads: “The fuel pump metering setpoint is implausible in the pump overflow mode.” “”Check the condition and connections of the high and low pressure hydraulic circuit components. Check and compare low fuel pressure at idle, at maximum speed without load and while driving with the maximum possible load. There should not be a pressure drop below 6 bar (gauge) (7 bar absolute), maximum pressure 8 bar gauge. If the pressure drops below 6 bar, the high pressure pump is worn out, there is resistance in the supply pipelines. Check the pumping on the coarse filter. It happens that in this pumping the rubber valve breaks and the fuel goes back.
