DTC P0600: A/T Control
- Check Input Signal Circuit
Turn ignition off. Disconnect ECM wiring harness connector. Disconnect A/T control unit wiring harness connector. Check continuity between the following connector terminals:- ECM connector terminal No. 24 and A/T control unit connector terminal No 10.
- ECM connector terminal No. 29 and A/T control unit connector terminal No 11.
- ECM connector terminal No. 30 and A/T control unit connector terminal No 12.
Continuity should be present. If continuity is present, go to next step. If continuity is not present, repair harness or connectors between ECM and A/T control unit.
- 2) Leave ignition off. Check continuity between the following terminals:
- ECM connector terminal No. 24 and ground.
- ECM connector terminal No. 29 and ground
- ECM connector terminal No. 30 and ground.
Continuity should be present. If continuity is present, go to next step. If continuity is not present, repair harness or connectors between ECM and A/T control unit.
- Disconnect ECM wiring harness connector. Check connector pins for damage or corrosion. Check all circuit connector for clean, tight fit. If fault is still present, repeat step 1).
