Monitor Scantool Data

Monitor DTC Status

1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode
2. Press F4 (DTAL) to select DTC information from the DTCs menu.
3. Confirm that "DTC Readiness Flag" indicates "Complete". If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions
4. Read "DTC Status" parameter




5. Is parameter displayed "History (Not Present) fault"?

CAUTION:
- History (Not Present) fault : DTC occurred but has been cleared.
- Present fault : DTC is occurring at present time.

YES
1) Fault is intermittent caused by poor contact in the sensor's and/or the ECM's connector, which was repaired but ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure
NO
1) [With ABS] Go to "Monitor Scan tool Data" procedure
[Without ABS system] Go to "Signal Circuit Inspection[Without ABS]" procedure

Monitor Scantool Data

1. With vehicle raised on a lift, start the engine and place transaxle in Drive. Let vehicle idle and verify speedometer indicates approx. 10 km/h or more (6 mph or more) on the instrument cluster.
2. Connect Scantool and select ABS system.
3. Monitor the "WHEEL SPD SENSOR-FR" parameter on the current data list.
A. Specification : 10 km/h or more (6 mph or more)
4. Is value within the specification?
YES
1) Wheel speed sensor is OK. Go to Go to "Signal Circuit Inspection[With ABS]" procedure
NO
1) Check for open or short circuit between wheel speed sensor (FR) and ABS control module If problems are found, repair as necessary and go to "Verification of Vehicle Repair" procedure.
If OK, Check wheel speed sensor (FR) as follow:
-Gap between ABS sensor and trigger wheel (Air gap : 0.3-1.1 mm (0.011-0.043 in))
-Trigger wheel condition
-Sensor resistance : Approx. 1,300-1,500 Ohms at 20 °C (68 °F)
Replace wheel speed sensor as necessary and go to "Verification of Vehicle Repair" procedure.
