Procedures/Diagnostic Mode 03: Interrogating Fault Memory
2. If necessary, erase the DTC memory. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Scan Tool Testing and
Procedures/Diagnostic Mode 04: Reset/Delete Diagnostic Data
3. If the DTC memory was erased, generate readiness code. See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
