General Description
The 4WD vehicle measures the G-sensor signal to solve for 4WD vehicle unique problems. For example all 4 wheels are locked early on a low-friction road or control response is delayed when road friction coefficients vary. The HECU uses a filtered signal, as a supplementary value, to determine the road friction coefficient. This value is used for the accurate calculations of assumed vehicle speed, or precise division of control starting points.
DTC Description
The HECU monitors the G-sensor voltage continuously,and sets this code if the G-sensor value is either higher than 0.5G for more than 20 seconds when vehicle speed is above 10 Km/h and brake switch is OFF, or if G-sensor value is lower than 0.1G for more than 60 seconds when wheel sensor minimum value is above 0.2G.
