Where is the ASD relay on a 2002 Jeep Liberty? ›

To locate the ASD relay look under hood in the bay. The "R39" relay is connected to the Jeep's ASD and is found in the "power distribution box" on the drivers side of the bay next to the firewall. The 2002 jeep liberty asd relay is located in the main fuse panel under the hood.

Well in fact is the fuse related to the Junction Box itself in the Power Distribution Center. As I had sent my question I discovered that that fuse ("JB Power") in fact conects the Junction Box with the Power Distribution Center.

The 2002 Jeep Liberty speedometer fuse can be found in the fuse panel that is under the driver's side of the dash. This controls all the gauges in the dash so if they are all not working that is the most likely culprit.

To locate the fuse specification chart for your vehicle or to learn how to change a fuse, refer to the "Fuses" section of your Owner's Manual.

If it fails, your engine will not crank, and it cannot be jumpstarted. If you are experiencing a no start condition, it may be the ASD relay, but it could be another problem. Seek immediate professional diagnosis and replacement by one of our expert mechanics.

The automatic shutdown (ASD) relay powers the ignition coils, fuel injectors, and alternator field in many Chrysler vehicles. If this part fails, the engine can stall, fail to crank, or lag while accelerating. The ASD relay is in the junction box under the hood.

They are all different types of fuses and relate to how they work. gFF fuses have a thinner element so they are faster operating than gG fuses. gG is a general-purpose fuse that can cope with lower overload current faults but will clear high short circuit faults. They are not as fast operating as other fuses.

A shunt is a part with an accurately known small resistance. It's easy to measure the voltage across this resistance as a measurement of current ( I = V/R). A fuse is a protective device whose resistance burns into a open circuit when rated current is exceeded.

gF fuse-links are for domestic use. gI-gG and aM fuse-links are for industri- al applications. Most ratings are available with an optional indicator. All industrial fuse-links have the option of a built-in striker. All cylindrical fuse-links have ceramic bodies and silver-plated ferrules.

On a newer model car the ECU/ECM controls everything ignition related AT LEAST. Timing, ignition, air. When the fuse blows, the engine control unit/module loses power and is unable to control the ignition process, the throttle (drive by wire) shuts and fuel ceases to be commanded to move. No spark is commanded to fire.

Can a blown fuse stop the speedometer? ›

Faulty fuses or wiring issues can also be the culprit of a bad speedometer, especially in older vehicles.

There is no fuse specific to the speedometer or odometer. Fuses that could affect the odometer can be found in the under hood fuse center, number 60 and the instrument center fuses number 14 and 15.

Generally the manufacturer's brand name and the actual part number should be enough to identify the right fuse. Unfortunately, this information is not always provided on the fuse, so this guide will help you to interpret the information that you might find on the fuse.

How many fuse boxes does a car have? Usually, you will find two fuse boxes in the car. One is located under the hood and the other is found in the dashboard or near the steering wheel.

The most straightforward is to inspect the fuse itself, where the amperage rating is typically noted on or near the top of the fuse. The second is to check the fuse diagram in the vehicle, to understand which fuse type is in each slot.

The ECM-power relay is verified that it needs to be replaced. The relay is located in the engine main fuse relay control box. The defective ECM-power relay is removed from the control box by pulling it straight up and out of socket. The new ECM-power relay is installed into the socket and the engine scanned for codes.

Diagnosing a failing accessory relay is as simple as placing your fingertips on its housing, flipping its switch, and checking for the presence of a small click-like pulse or noise.

A P0122 code is the generic OBD-II code defined as “Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input.” This code relates to the vehicle's Engine Control Module (ECM) and TPS Sensor Circuit A output voltage and is triggered when the voltage falls below the sensor's anticipated range.
