Troubleshooting, general work
instructions
When troubleshooting, it’s important that the work is structured and
logical. The point of the troubleshooting described in the mainte-
nance manual is to exclude components as error source so that the
real error source can be pin-pointed. A proposal for structured work
method is described below.
When troubleshooting, it’s important to understand how the ma-
chine functions, certain malfunctions can be pin-pointed directly us-
ing function descriptions. In the sections
0–12 there are descriptions
of the machine’s different functions.
Troubleshooting procedure
1 Check that there is battery voltage available.
• Battery disconnect switch, must be in position 1.
• Battery voltage, should be 22–30 V.
• Fuses, check that they are intact.
2 Check that all oil and fluid levels are normal.
• Fuel
• Engine oil
• Transmission oil
• Oil for brake system
• Hydraulic oil
• Coolant
• Washer fluid
3 Check if there are error codes.
4 If there are error codes, use the error code lists as a guide. See
Troubleshooting with error code, example page 5 .
In the error code lists there are recommended actions for every
error code. Error code lists are found in section
D Error codes .
5 If there is no error code, or problem remains, use the function
description for function in question in section 0–12 .
In the function description there’s information about which
components are involved in the function and how these com-
ponents work together. In certain cases, there’s information
about which conditions apply to enable activation of the func-
tion. Measuring points are marked with flags (C for pressure
check connections, D for diagnostic menu).
