range?
Go to Step 2. Go to Step 7.
2 While ignition switch ON, check voltage
between terminal “E12-2” and “E13-15” of dis-
connected harness side TCM coupler.
Is it 10 – 14 V at “R” range and 0 V at the other
range? Go to Step 3. Go to Step 7.
3 While ignition switch ON, check voltage
between terminal “E12-3” and “E13-15” of dis-
connected harness side TCM coupler.
Is it 10 – 14 V at “N” range and 0 V at the other
range? Go to Step 4. Go to Step 7.
4 While ignition switch ON, check voltage
between terminal “E12-9” and “E13-15” of dis-
