Jeep Asd Relay

ASD or Automatic Shutdown Relay (ASD) controlled far and wide the facility provide modules like ignition coil, fuel pump, and different parts. The main purpose is to close off the fuel power and different ignition programs whilst you off the automobile key. It helps to forestall your automotive from dieseling, firs, and different varieties of issues.Jeep uses and engine control device this is constructed by way of Chrysler. The ASD relay (Automatic ShutDown relay) is controlled by the PCM (Powetrain Control Module). The PCM wishes to peer a CKP signal (Crankshaft Position Sensor) and CMP (Camshaft Position Sensor) signal in the right kind sync before the ASD relay will probably be grew to become on by way of the PCM.1993, 1994, 1995 4.0L Jeep Grand Cherokee. ASD relay troubleshooting notes: The auto shut down (ASD) relay will get power from fuse #6 (15 Amp) and fuse #2 (20 Amp) of the Power Distribution Center (PDC). The PCM turns on the ASD relay and the gasoline pump relay at the exact same time and thru' the same circuit (PNK cord).Shop AutoZone for Jeep Compass Multiple Purpose Relay.

Diagnose a no start Jeep condition

Why your Jeep gained’t start

If you personal a overdue style Jeep with a no start Jeep drawback, this newsletter would possibly lend a hand. This help article pertains to 2010 through 2012 Jeep Avenger, Jeep Compass and Jeep Patriot, even though the trouble taking pictures applies to many other Jeep and Chrysler products since they all use identical wiring

The symptoms seem as a crank, no start where the starter engages and turns the engine but it is going to no longer stir up.

How the Jeep system works

The ignition switch on past due fashion cars doesn’t if truth be told switch power to the starter, ignition or fuel system. The transfer acts handiest as a sign to the PCM/frame control module. When you turn the key, the PCM/BCM anti-theft machine determines whether you’re the usage of the proper key. If so, the PCM supplies floor to the car shutdown relay (ASD), often known as the MAIN relay which then operates to offer power to the definitely built-in power module (TIPM) which provides power to the fuel injectors and ignition coils. If there’s a topic with the ASD relay or the wiring to the ASD relay, you’ll get a no get started Jeep condtion.

What goes incorrect with Jeep beginning gadget?

In their knowledge, Chrysler positioned the ASD relay below the battery and at the back of the motive force’s facet headlight. Over time, corrosion can rot out the wires to the ASD relay socket.

Diagnose no start Jeep

Here’s where to start out your analysis. First, scan for hassle codes. If the ASD relay or wiring are bad, you will get a P0685-ASD/MAIN CONTROL CIRCUIT or P0688-ASD RELAY CONTROL SENSE trouble code.

Check fuses first:

The battery supply power to the TIPM. Fuse 33 10A within the TIPM provides energy to 1 facet of the ASD relay regulate coil at the purple/light blue wire. Fuse #18 40A supplies energy to the ASD relay contacts on the pink/yellow wire.

Once the important thing passes the anti-theft take a look at, the PCM supplies ground to the control coil facet of the ASD relay at the brown white twine. Once the ASD relay receives flooring from the PCM, the contacts shut and the relay sends power again to the TIPM on the brown/white twine. The TIPM routes that energy to Fuse 32 30A, Fuse 26 15A and Fuse 23 15A.

Fuse 32 sends power back to the PCM so the PCM can observe the status of the ASD.

Fuse 26 supplies power to the gasoline injector and Fuse 23 provides energy to the ignition system

So test all the ones fuses

Then test ASD relay wiring

Shops have found serious corrosion at the ASD relay socket terminals that has ended in corrosion all the means down some wires. Shops have also discovered damaged wires beneath the ASD major relay box so far as 3” clear of the field. How to check Jeep primary relay

Remove the principle relay from the socket. Check for corrosion. If just right, use a virtual voltmeter to check for power in the main relay socket. With the key became to the RUN place, test for battery power on two terminals and floor on one terminal within the socket. If you don’t see battery voltage on two terminals and the fuses indexed above take a look at just right, check the purple/light blue wiring from the TIPM to the main relay box. If you don’t see ground from the PCM within the socket, take a look at for floor on the brown/white cord coming from the PCM. If you continue to don’t see ground and also you don’t have an anti-theft issue, you could have a nasty ignition transfer. Grab a wiring diagram and specifications and check for right kind IGNITION switch operation.

If you see those voltages and flooring, put the relay again in the socket and check for battery voltage on the red/yellow wire. If you don’t see battery voltage, chances are high that the relay is bad.
