Compare the scan tool readings with the numbers listed on the Transmission Simulator. Do the readings on the Transmission Simulator match the scan tool readings ± 0.2 volts? Yes >> Replace Transmission Solenoid/TRS Assembly per the Service Information. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMIS- No >> Go To 4 4. CHECK THE (T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO Turn the ignition off to the lock position. Disconnect the Transmission Simulator, Miller tool #8333. Disconnect the TCM harness connector. Measure the resistance between ground and the (T54) Transmission Is the resistance below 5.0 ohms? Yes >> Repair the (T54) Transmission Temperature Sensor Signal circuit for a short to ground. Perform 45RFE/545RFE TRANSMISSION VERIFICATION No >> Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or Perform 45RFE/545RFE TRANSMISSION VERIFICATION 5. 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 DTC EVENT DATA to help identify the conditions in which the DTC was set. Were there any problems found? Yes >> Repair as necessary. Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMIS- No >> Test Complete. 21 - 456 AUTOMATIC TRANSMISSION 545RFE - ELECTRICAL DIAGNOSTICS - (DIESEL) KJ |
