Need some help or ideas. EU- Spec, 1990 300ZX Twin Turbo Targa Manual 2+2 The ABS light appears when I start driving, but disappears after the car is shut down. Any possible reason for this? I’ve already checked a few things: all ABS sensors have been cleaned and inspected, and the wiring shows no signs of wear or damage. The ABS control unit showed five long red lights, which should indicate code 50, but as far as I know, it’s not an official code. The speedometer isn’t working, so that might be related to why the ABS light turns on after driving. We removed the Vehicle Speed Sensor (VSS) located near the transmission, and everything appeared fine—nothing out of place. The VSS should send data to the ECU, right? Before it goes to the speedometer. Any help would be greatly appreciated. Thanks! Eric
