A80 Pro Intelligent Diagnosis System
36
The Volvo series models are capable of diagnosing 10 systems in terms of self-diagnostic
functions, and in each system diagnosis, they can be divided into six modes:
1 fault code reading
2 control component action test;
3 Each control element operates simultaneously to control the test;
4 Develop component motion command control test;
5 numerical reading analysis instructions;
6 Reset the microcomputer memory command.
When diagnosing the car, you can use the jumper on the diagnostic stand directly into the
different diagnostic holes, and press the buttons on the diagnostic stand to select various specific
diagnostic modes by pressing 1 to 6 respectively.
To clear the fault code, first insert the diagnostic jumper into the corresponding diagnostic hole
of the system to be diagnosed, set the ignition switch to ON, and read the fault code first, until all fault
codes are displayed, the LED light is continuously on. From then on, press and hold the diagnostic
button for more than 5 seconds to clear the fault code.
Crown auto ABS fault self-diagnosis system
The new Crown sedan uses an anti-lock braking system (ABS). If the system fails, the fault
self-diagnosis system in the anti-lock braking system will identify the fault that occurred, and the
microcomputer (ABSECU) will represent the fault. The code is stored and the fault message is
communicated to the owner via the ABS warning light (installed in the upper left corner of the
instrument cluster).
