Sidekick 4 Door 4WD L4-1.8L DOHC MFI 16V (1996)
This system controls the TCC relay, one of the components that controls the torque converter clutch. A circuit diagram of this system is shown in Figure
1.
The TCC solenoid valve, under the control of the A/T oil pressure switch and TCC relay, opens and closes the A/T oil passage to lock and unlock the
torque converter clutch.
The ECM controls the relay using information from the following sensors:
^
Throttle Position Sensor (TPS)
^
Camshaft Position Sensor (CMP)
^
Engine Coolant Temperature Sensor (ECT)
^
Vehicle Speed Sensor (VSS).
The ECM engages the relay only under the following conditions:
^
Engine is running
^
Engine coolant temperature is above 60°C (140°F)
^
Throttle valve opening is between 6.40 and 62.5
^
Vehicle speed is higher than - 40 mph (64 km/h, 8-valve engine) or - 47 mph (75 km/h, 16-valve engine, late type ECM only).
Battery voltage is applied to the TCC solenoid valve under the following conditions:
^
The relay is ON
