Diagnostic Test

CHECK IF THE DTC IS CURRENT
Turn the ignition off to the lock position.

CAUTION: Properly support the vehicle and raise all drive wheels off the ground.

Release the parking brake.

Start the engine in park.

Place the transmission gear selector in drive, release foot from brake.

WARNING: Be sure to keep hands and feet clear of rotating wheels.

With the scan tool, monitor the Output Speed Sensor RPM.

Is the Output Speed Sensor RPM below 100 RPM?

Yes
1. Go to 2.
No
1. Go to 9.
CHECK THE OUTPUT SPEED SENSOR
Turn the ignition off to the lock position.

Remove the Starter Relay.

CAUTION: Removal of the Starter Relay will prevent the vehicle from being started in gear.

WARNING: The Starter Relay must be removed from the PDC. Failure to do so can result in personal injury or death.

NOTE: Failure to remove the Starter Relay can cause a Transmission - No Response condition.

Install the Transmission Simulator, Miller tool #8333.

Ignition on, engine not running.

With the Transmission Simulator, set the selector switch to 3000/1000 and the Input/Output switch to ON.

With the scan tool, monitor the Input and Output Speed Sensor RPM

Does the Input Speed read 3000 RPM and the Output Speed read 1000 RPM (± 50 RPM)?

Yes
1. Replace the Output Speed Sensor per the Service Information.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
No
1. Go to 3.
CHECK THE (T14) OUTPUT SPEED SIGNAL CIRCUIT FOR AN OPEN

Turn the ignition off to the lock position.

Disconnect the Transmission Simulator, Miller tool #8333.

Disconnect the PCM harness connectors and connect Miller tool #8815.

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller tool #8815 to perform diagnosis.

Measure the resistance of the (T14) Output Speed Signal circuit from the Output Speed Sensor harness connector to the appropriate terminal of Miller tool #8815.

Is the resistance above 5.0 ohms?

Yes
1. Repair the (T14) Output Speed Signal circuit for an open.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
No
1. Go to 4.
CHECK THE (T13) SENSOR GROUND CIRCUIT FOR AN OPEN

Measure the resistance of the (T13) Sensor Ground circuit between the Output Speed Sensor harness connector and the appropriate terminal of Miller tool #8815.

Is the resistance above 5.0 ohms?

Yes
1. Repair the (T13) Sensor Ground circuit for an open.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
No
1. Go to 5.
CHECK THE (T14) OUTPUT SPEED SIGNAL CIRCUIT FOR A SHORT TO GROUND

Remove the Transmission Control Relay.

Place a jumper wire between the Fused B(+) circuit and the Transmission Relay Output circuit in the Transmission Control Relay connector.

Ignition on, engine not running.

Measure the voltage of the (T14) Output Speed Signal circuit.

Is the voltage above 0.5 volts?

Yes
1. Repair the (T14) Output Speed Signal circuit for a short to voltage.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
No
1. Go to 8.
CHECK THE (T13) SENSOR GROUND CIRCUIT FOR A SHORT TO VOLTAGE

Measure the voltage of the (T13) Sensor Ground circuit.

Is the voltage above 0.5 volts?

Yes
1. Repair the (T13) Sensor Ground circuit for a short to voltage.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
No
1. Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM per the Service Information. With the scan tool, perform Quick Learn.
2. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST .
CHECK WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.

Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

Wiggle the wires while checking for shorted and open circuits.

With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
