How to Clear Diagnostic Trouble Codes

When the sensing and diagnostic module (SDM) receives the CODE ERASE command from the scan tool, the SDM:
- Clears the entire fault memory.
- Turns OFF the warning lamp.
- Resets for fault detection.

External Fault
Service personnel can reset the SDM and turn OFF the warning lamp if the fault is an external fault.

Internal Fault
An internal fault of the SDM or a CRASH RECORDED fault code cannot be reset.
In the case of an internal fault of the SDM or a CRASH RECORDED fault code, the SDM must be replaced.

Voltage-Low Fault
The SDM will turn OFF the VOLTAGE LOW fault as soon as the voltage recovers.
