Shift Position Signal

Tt Voltage Measurement:

- Warm up the engine.

Coolant temperature: 80°C (176°F)

- Turn the O/D switch to ON.
- Place the pattern select switch in "Normal" and the shift lever into the D range.
- During a road test (above 10 km/h or 6 mph) check that voltage at the Tt terminal is as indicated below for each up-shift position.

Tt Voltage Measurement:

Table

- If the voltage rises from 0V to 7V in the sequence shown in the table, the control system is okay.

HINT: Determine the gear position by a light shock or change in engine rpm when shifting. The lock-up clutch will turn ON only infrequently during normal 2nd and 3rd gear operation. To trigger this action, press the accelerator pedal to 50% or more of its stroke. At less than 50%, the voltage may change in the sequence 2V - 4V - 6V - 7V.
