C1275 Longitudinal G Sensor Range/Performance error - Scantool Diagnostics:_:Monitor Scantool data

Monitor Scantool Data

1. Connect scantool to Data Link Connector(DLC)
2. Ignition "ON" & Engine "OFF".
3. Start and drive vehicle in gear and maintain vehicle speed is approx. 10km/h or more (6mph or more) and then accelerate and decelerate the vehicle several times.
4. Monitor the "G-sensor" parameter on the Scantool.
A. Specification : Below 0.4G (at a uniform speed)
It is a normal condition if the data is changed while accelerating or decelerating the vehicle




Fig 1) Test Condition : Drive vehicle in 10km/h or more (6mph or more)
Normal Data
5. Is parameter displayed within specifications?
YES
1) Fault is intermittent caused by poor connection in G sensor harness and/or HECU's connector or was repaired and HECU memory was not cleared.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
