If DTCs are displayed in "PID 02":
- Repair stored malfunctions according to DTC table:
- SAE P0xxx-DTCs. Refer to SAE P0xxx-DTCs
- SAE P1xxx-DTCs. Refer to SAE P1xxx-DTCs
- SAE P2xxx-DTCs. Refer to SAE P2xxx-DTCs
- SAE U0xxx-DTCs. Refer to SAE U0xxx-DTCs
- End diagnosis and switch ignition off.
NOTE:
- The DTC table is sorted by SAE code.
- "Emission"-relevant malfunctions are indicated in the instrument cluster via the Malfunction Indicator Lamp (MIL). Refer to Malfunction Indicator Lamp (MIL) in instrument cluster
- Erase DTC memory after repairing malfunction. Refer to Diagnostic mode 4: Reset/erase diagnostic data
