Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Scan Tool Testing and
Procedures/Diagnostic Mode 3: 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 4: Reset/Delete Diagnostic Data
3. If the DTC memory was erased, generate readiness code.
-
End of diagnosis.
