____________________________________________ Transmission/Transfer Case 5-59 ® 05745159 DTC P0712 Fluid Temperature Circuit Low/High Step Action Value Yes No 1 Perform transmission fluid checking procedure. — Go to Step 2 — 2 1. Install the scan tool. 2. Turn the ignition switch to “on” position. Important: Before clearing DTC(s), use the scan tool to record “Freeze Frame” and “Failure Records” for reference, as data will be lost when 3. Record the DTC “Freeze Frame” and “Failure Records.” Does the scan tool display a “TFT Sensor” signal voltage less than 0.2 volts Go to Step 3 Refer to Diagnostic Aids 3 1. Turn the ignition “off.” 2. Disconnect the transmission 20-way harness connector. 3. Turn the ignition “on.” Does the scan tool display a “TFT Sensor” signal voltage greater than 4.92 volts Go to Step 4 Go to Step 8 4 1. Install 05743837 Jumper Harness on transmission side of the 20- 2. Using multimeter and Connector Test Adapter Kit, measure resis- Is resistance high? Check charging system Refer to Diagnostic Aids Go to Step 6 5 1. Remove transmission oil pan. 2. Check the internal wiring harness for a short to ground. Was a problem found? — Go to Step 7 Go to Step 6 6 1. Disconnect the internal wiring harness. 2. Measure the resistance of TFT sensor. Is the resistance high? — Refer to Diagnostic Aids Go to Step 7 7 Replace the internal wiring harness. — Go to Step 11 — 8 Check circuit 359 for short to ground. — Go to Step 11 Go to Step 9 9 Check the TCM/PCM for faulty connections. — Go to Step 11 Go to Step 10 10 Replace the TCM/PCM. — Go to Step 11 — 11 1. After the repair is complete, use the scan tool to select “DTC,” then 2. Select “Specific DTC” and enter DTC “P0712.” 3. Ensure the following conditions are met: • TFT sensor indicates a voltage greater than 0.33 volts for 10 sec- onds. Has the last test failed? — Begin diagnosis again, Go to Step 1 Repair ver- ified, exit DTC table. |
