Machine failures are unavoidable and sometimes really upsetting when there is no technician to turn to. So this is an article that can help you save much time and unnecessary repair cost. 

Here you're getting to know the conversion of the SAE fault code to the Volvo excavator fault code, the Volvo EC140CL fault code and the Volvo EC210B fault code etc. Details are as follows:

Machine serial number:

　　EC330B 10236

　　EC360B 10829

The maintenance tool VCADS Pro uses a SAE type of fault code. The design of the SAE fault code includes identification numbers such as MID, PID and FMI.

MID: Message Identification Deion (indicating control component identification). Each control component has a unique number.

PID: Parameter Identification Deion (represents the identification of parameters/values). Each parameter has a unique number.

PPID: Proprietary Parameter Identification Deion (represents Volvo unique parameter value / identification). Each parameter has a Volvo unique number.

SID: Subsystem Identification Deion (represents component identification). The SID numbers are determined by which control component (MID) they are transmitted from. Each control component has its own sequence of SID numbers. The exceptions are the SID numbers 151-255, which are common to all systems.

PSID: Proprietary Subsystem Identification Deion. (Indicating Volvo unique component identification).

FMI: Failure Mode Identifier (indicating the type of fault identified).

The troubleshooting information is based on the fault code of the Volvo excavator. When reading the fault code on VCADS Pro, the SAE fault code must be converted to a Volvo excavator fault code for further troubleshooting. The following is a conversion table for the SAE fault code to the Volvo excavator fault code.

Model: Volvo 240 excavator

Engine part fault code:

The ER32 is the fault of the flow control valve (the hydraulic hammer option). The standard excavation does not carry this. If the alarm occurs, it may be a false alarm of the VECU or a line problem.

ER31 is the fault of the power shift valve (proportional solenoid valve on the hydraulic pump)

1-2. The battery relay is abnormal.

A-1. No electromechanical A adjustment.
