TE11 - Check Continuity of TFT and SIG RTN Circuits

- Key "OFF".

- Transmission connector disconnected.

- Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

- Install breakout box, leave PCM disconnected.

- Measure resistance between Transmission Fluid Temperature (TFT) circuit at transmission vehicle harness connector and TFT test pin 49 at breakout box.

- Measure resistance between SIG RTN circuit at transmission vehicle harness connector and test pin 46 at the breakout box.

- Are both resistances less than 5.0 ohms?

Yes -- Go to TE12. TE12 - Check TFT Circuit For Short to VPWR

No -- Service open circuit(s). Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
