DTC P0600: A/T Control
NOTE:
In case of the diagnostic item, the freeze frame data will not be stored in the ECM. This diagnosis does not have 2 trip detection logic, and will not light up the MIL.
- Check Input Signal Circuit
- Turn ignition off. Disconnect ECM wiring harness connector. See Figure. Disconnect A/T control unit wiring harness connector. See Fig 1. Check continuity between the following connector terminals: See Fig 2.
- 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.
- Leave ignition off. Check continuity between ground and the following terminals:
- ECM connector terminal No. 24.
- ECM connector terminal No. 29
- ECM connector terminal No. 30.
Continuity should not be present. If continuity is not present, repair harness or connectors between ECM and A/T control unit. If continuity is present, go to next step.
- Check ECM and A/T control unit wiring harness connector pins for damage or corrosion. Check all circuit connector for clean, tight fit. If fault is still present, repeat step 1).
