Relay tripped shutdown - Yamaha RX-V661 Receiver

P0685 DODGE - Auto Shutdown Relay Control Circuit Failure
Possible causes - Faulty Engine Control Module (ECM) power relay
- ECM power relay harness is open or shorted
- ECM power relay circuit poor electrical connection
- Faulty (ECM
Possible symptoms:
Engine Light ON (or Service Engine Soon Warning Light) P0685 Dodge Description: Short or open in Auto Shutdown (ASD) relay circuit, this relay is under the hood in the relay center.

Jeep doesn't use a fuel pump reset AKA "Inertia activated fuel pump cut off switch" You have what is called the ASD relay under the hood that will trip the pump power in a crash. Follow the link for more info on the ASD Symptoms of Bad or Failing Automatic Shutdown Relay YourMechanic Advice

P0685 CHRYSLER - Auto Shutdown Relay Control Circuit Failure

Short or open in Auto Shutdown (ASD) relay circuit
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
Possible Causes
- ASD relay circuit is open or shorted
- Failed Auto Shutdown relay
- Failed ECM
Tech Notes
Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

P0688 CHRYSLER - Auto Shutdown Relay Control Circuit Low

The Front Control Module (FCM) has detected the supply voltage below an acceptable value
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
Possible Causes
- ASD relay circuit is open or shorted
- Failed Auto Shutdown relay
- Failed ECM
Tech Notes
Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

gee 1, last year of Cherokee is 2001, so you meant Grand right??????
gee2, wont start or stalls, no other symptoms????? just 1 DTC, no others using a real scan tool? that be first huh?
Geewise 3, what engine, wow, wrong car, no engine or country.?

the FSM covers this, and the ASD has 8 ways to trip off line'
UP TO 8 ways , just like old wonder bread had.

answering for 2004 GC, (i actually look it up in the real book)
not google butchered DTCs.
P means power train, 1 means factory codes.
a 3 coin toss lands...
2004 GC, vin N, 4.7L v8 automatic,


it reads. verbatim.
Trouble Code: P1389
No Auto Shutdown Relay Output Voltage To PCM
Number of Trips to Set Code: 1

• Catastrophicmonitor failure.

Trouble Code Conditions:
Engine cranking; and the PCM did not detect any voltage on the ASD Relay Output circuit to the PCM during the CCM test.
Possible Causes:

1. ASD relay connector is damaged, loose or shorted
2. ASD relay output circuit is open between the relay and PCM
3. ASD relay power circuit is open (test power from Fused B+)
4. ASD relay is damaged or has failed
5. PCM has failed (nah)

it means, to me.

• the relay is unplugged
• or fuse blown "fused B+" (a top reason, world wide)
• the relay is bad.

Its called an EEC relay, should be in the relay box or along the fender near the battery.

There is no switch. The relay gets a signal from the computer. If there is no signal from the crank position sensor the computer will not close the relay. If it runs with the relay bypassed, chances are good that the relay itself is bad.

the auto shut down relay is not like a fuse that can shut the engine off the name it has actually has not much to do with its function.. the relay is controlled by the computer .. its main function is to stop run-on and turns off o2 heaters power to coil and injectors if you had the key in the run position and engine not running your battery would dies faster than a drive in movie.. but anyway if your stalling and think its the relay failing just swap it with another one that looks the same from the PDC.. what you may have is a bad fuel pump or even a crank sensor have you had it scanned for codes? sometimes but not always you may have a code for lean upstream o2 if the pump is failing but not always.. and for the crank sensor you may have a crank shaft position sensor performance or cam/crank sensor code ..

Auto shutdown relay and fuel pump relay are by the battery under a cover.
