- Clear the DTC from the PCM memory using the WDS or equivalent.
- Verify the following conditions and correct if necessary:
- All accessory loads (A/C, headlights, blower fan, rear window defroster) are off.
- Initial ignition timing and idle speed are within the specification.
- TEN and GND of DLC are not connected.
- Verify that all of the following PIDs are within the following specifications. All PIDs must be within specifications from Step 5 to Step 6.
- BARO:more than 72.3 kPa {542 mmHg, 21.3 inHg}
- IAT:5-35°C {41-95°F}
- FTL:15-85%
- B+:above 10.9 V
- With the vehicle stopped, race the engine at the engine speed indicated, and then drive the vehicle as shown in the graph. The driving conditions before driving at constant speed are not specified. If possible, monitor RPM PID for engine speed and FAN2 PID (with A/C), FAN1 PID (without A/C) for cooling fan status during this procedure.
