USER MANUAL For DS2020/2021

Chapter 4 - 4

B. DTC Erase (Clear fault code)

1. Pulse signal type

a. Pulse signal type does not support bi-directional serial communication,

therefore, a scanner is unable to send a command to the control module

to erase the DTC information from memory.

These old cars require you to remove battery terminal to clean up

diagnostic information from control module memory.

Removing the battery terminal will get rid of all information contained in

the car stereo and other electronic devices. And it may not effectively

erase the fault codes in some cars. Refer to the original repair manual

for further information.

Check if DTC information is properly removed by reading the trouble

code again after erasing the code.

2. Serial communication type

a. DS2020/2021

sends a command to the control module to erase DTC

information stored in memory, and the control module replies thereupon.

b. Check if DT

C information is properly removed by reading the trouble

code again after erasing the code
