- The driver seat control unit counts the pulse and calculates the lifting
(rear) amount of the seat.
Component Function Check
1. CHECK FUNCTION
- Select "LIFT RR PULSE" in "DATA MONITOR" mode with CONSULT.
- Check lifting sensor (rear) signal under the following conditions

Diagnosis Procedure
1. CHECK LIFTING SENSOR (REAR) SIGNAL
- Turn ignition switch ON.
- Read voltage signal between driver seat control unit harness connector
and ground with oscilloscope.

2. CHECK LIFTING SENSOR (REAR) CIRCUIT
- Turn ignition switch OFF.
- Disconnect driver seat control unit and front power seat LH
[lifting motor (rear)].
- Check the continuity between driver seat control unit harness
connector and front power seat LH [lifting motor (rear)] harness
connector.

- Check the continuity between driver seat control unit harness connector
and ground.

3. CHECK LIFTING SENSOR (REAR) POWER SUPPLY
- Connect driver seat control unit.
- Turn ignition switch ON.
- Check the voltage between front power seat LH [lifting motor
(rear)] harness connector and ground.

4. CHECK LIFTING SENSOR (REAR) POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect driver seat control unit.
- Check the continuity between driver seat control unit harness
connector and front power seat LH [lifting motor (rear)] harness
connector

with temperature. Because of this, it is important
to select the engine oil viscosity based on the
temperatures at which the vehicle will be operated
before the next oil change. Choosing an oil
viscosity other than that recommended could
cause seri ...
