TF13 - Check TSS Circuit Continuity
- Key "OFF".
- Transmission 12 pin connector disconnected.
- Install breakout box or 4EAT tester. Leave Powertrain Control Module (PCM) disconnected.
- Measure resistance between test pin 24 and TSS(+) circuit at transmission 12 pin vehicle harness connector.
- Measure resistance between test pin 44 and TSS(-) circuit at transmission 12 pin vehicle harness connector.
- Are both resistances less than 5.0 ohms?
Yes -- Go to TP14. TF14 - Check PCM For Internal Shorts
No -- Service open circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
