Power relay control circuit high.

If a defective control module is suspected the better option would be to refer the application to the dealer or other competent repair facility for professional diagnosis and repair. This diagnostic trouble code dtc is a generic powertrain code which means that it applies to all 1996 newer vehicles vw bmw chrysler acura audi isuzu jeep gm etc. The circuit that powers the electromagnet s coil is completely separate from the circuit that is switched on or off by the relay s switch so it s possible to use a relay whose coil requires just a few volts to turn a line voltage circuit on or off. It is referred to as the transmission control relay output circuit or switched battery.

This diagnostic trouble code dtc is a generic powertrain code and applies to many obd ii vehicles 1996 newer. When the relay is off no power is supplied to the solenoid pack and the transmission is in limp in mode. It is referred to as the transmission control relay output circuit or switched battery. In most cases when the pcm stores a p0687 code it s because it has detected overly high voltage from its power supply.

It s a contact type relay activated with a signal wire from the ignition switch. When the relay is off no power is supplied to the solenoid pack and the transmission is in limp in mode. P0686 ecm pcm power relay control circuit low p0687 ecm pcm power relay control circuit high. Battery positive voltage is supplied.

What does that mean. Ecm pcm power relay control circuit high. The pcm powertrain control module also known as ecm or engine control module in other vehicle makes comes with a power relay that provides battery voltage safely to the right pcm circuits. Tcm power relay control circuit high.

The powertrain relay is a normally open relay. The relay armature is held in the open position by spring tension. Codes related to p0685. Learn what engine control module power relay control circuit high means location and how to repair.

Although generic the engines differ between brands and may have slightly different causes for this code. What does p0887 mean. The relay output is fed back to the powertrain control module. A p0687 code is stored when the pcm powertrain control module detects an incorrect abnormal or erratic voltage reading from the relay control circuit that supplies it with its power.

The relay output is fed back to the powertrain control module.
