(NovaVortex Wrote: under live data is the 4 wheel speed sensors reading km as you drive. i had isuzu yesterday and only 3 were reading and found wire broken inside sleeving on the fourth one. i personally dont think is power problem becuase you only complain of L/R wheel fault. if power problem then all should give fault, actually should say NO COMMUNICATIONyes..under the live data - 4 wheel sensors Front Left, Front Right, Right Rear - 0 when ideal (but reads soonest i start drive.But the Left Rear - Read 40976 (In Red) when idle - and does not change when driving.An again when i disconnected it completely from the inner sleeve. Same reading on it. i change it with the one on the right rear (same reading).)
