Auto Shutdown (ASD) Relay
WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
The ASD relay is a cut-off relay for the following components.
- Fuel Injector Driver Module
- Ignition Coil
- Low-Pressure Fuel Shutoff Solenoid
When ignition switch is turned to RUN position, PCM energizes ASD relay, which powers these components. If PCM does not receive a crankshaft signal shortly thereafter, PCM will de-energize ASD relay, and power to these components is cut off.
