A/T Control Unit
- Turn ignition on. Check voltage at each control unit terminal. See appropriate EC-AT CONTROL UNIT CHART. If voltage is not as specified at any terminal, repair or replace component(s), wiring or A/T control unit.
- Disconnect connectors at EC-AT control unit. Using an ohmmeter, connect one test lead to terminal 2S and the other to terminals 2K, 2M, 2N, 2O and 2P. See appropriate EC-AT CONTROL UNIT CHART. If continuity is present at all terminals, EC-AT is okay. If continuity is not present at any terminal, replace EC-AT.
