How to repair a power relay in a TCM?

How to repair a power relay in a TCM?

Connect the meter between the TCR control terminal on the TCM and the relay control terminal in the fuse box. The meter should read a numeric value. If the meter read out of limits (OL) there is an open circuit. Consult the factory wiring diagram and repair the power side of the circuit as necessary.

What to do if your TCM is not working?

Turn the vehicle ignition on and use a test light to check for power to the TCR. Connect the test light between the battery negative terminal and the relay control terminal in the fuse box. The light should illuminate. If it does not, there is a problem on the control side of the circuit, or the TCM is not commanding the relay on.

How to tell if a TCM is supplying power to a TCR?

If the circuit between the TCM and TCR is good, you’ll want to check that the TCM is supplying power to the TCR. To do this, turn the ignition on and set the meter to read volts. Connect the negative meter lead to the battery ground terminal and the positive meter lead to the TCR control terminal on the TCM.

Why is my TCM Not reading the speed sensor?

A corroded connector or a problem with the wiring could be the problem, and the usual solution is to replace the input speed sensor. The speed sensors tell you how fast your output or input shaft is moving. If the TCM can’t read this information, your speedometer won’t read accurately. The output speed sensor may need to be replaced.

When is the Transmission Control Relay ( TCR ) off?

The transmission control relay (TCR) is used to supply power to the transmission solenoid pack during normal operation. When the relay is off, no power is supplied to the control pack and the transmission goes into “limp mode”. The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM).

What happens when the power relay is off?

When the relay is off, no power is supplied to the control pack and the transmission goes into “limp mode”. The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM).

What causes low voltage in the PCM relay?

If you do not find any visible damaged or disconnected wires and there are no blown fuses, then you can start to test for voltage in the PCM relay. If you do not find any low voltage at both the primary and secondary terminals on the PCM relay, then the cause of the issues is probably a defective ignition switch in the relay.
