MPX (Multiplex Communication) System
System Diagram MPX has several communication protocols, such as CAN, LIN, AVC-LAN, AVC-LAN plus and BEAN. CAN is classified into 2 types, V Bus, Movement Control Bus and MS Bus. V Bus and Movement Control Bus: High Speed (500 kbps) for the power train, chassis and body electrical systems. MS Bus: Medium Speed (250 kbps) for the body electrical system. Main Body ECU has gateway function which connects the V Bus and MS Bus divided into two in order to reduce a communication load. Combination Meter does not have gateway function. NOTE: One CAN bus line can connect 13 ECUs maximum. Terminating Register is located to ECM and Combination Meter for V Bus Network Gateway ECU and Suspension Control ECU for Movement Control Bus Combination Meter and Main Body ECU for MS Bus

-Q -V -C -A Operation The operation from Sitting Mode to Folding Mode is as follows Sitting Mode Folding Mode (3) Folding Switch (5) (4) (2) (1) [Operation] When one of the following conditions is met, the automatic folding-up function operates. The back door is open and the engine switch is OFF. The back door is open, the engine switch is ON and the shift lever is in the P position. (4) Push the folding switch. The No.1 & 2 rear seat lock control lever assembly operate to unlock the seatback. The seatback folds forward. At the same time, the headrest folds. The seatback lock switch turns on. Link Hook Cable

-Q -V -C -A Operation The operation from Sitting Mode to Folding-up Mode is as follows (2) Folding Mode Folding-up Mode Retract Switch (4) (8) (5) (1) (6) (3) (7) [Operation] Push and hold the retract switch. The operation from setting mode to folding mode is the same. The seat lock control lever operates to release the No.1 & 2 floor striker. The buzzer sounds twice. The seat retracts by the folding-up motor. The seat lock switch turns on and then the fold seat lock motor operates. The striker or seat is locked to the fold seat lock assembly.

Service Point (Power Seat System)
-Q -V -C -A Fold Seat Lock Assembly When the fold seat lock assembly malfunctions locking the striker,replace it in the following procedure (1) Folding-up Mode Folding Mode Reclining Cover Striker Fold Seat Lock Assembly (2) (3) Seat Back Cover (4) Malfunction Lever (3) Folding-up Motor [Procedure] Remove the reclining cover and turn over the seat back cover Disconnect the striker from the seat Remove the folding-up motor and return manually the seat to the folding mode Pull the lever of fold seat lock assembly and cancel the lock Replace a new fold seat lock assembly

-Q -V -C -A Operation The operation from Folding-up Mode to Folding Mode is as follows Folding-up Mode Folding Mode Return Switch (2) (6) (4) (1) (3) (5) [Operation] [Operation] Push and hold the return switch. The buzzer sounds twice. The striker of seat is released to the fold seat lock assembly. The seat returns by the folding-up motor. The No.1 & 2 floor striker lock. Return the seatback and headrest manually.

Multi-information Display
Power Seat System -W -Q -V -C -A Warning If the fold seat control ECU detects the malfunction, it warns as follows Failure Condition Buzzer Indicator Light Multi-information Display ON Blink When the operation switch is turned off 10 sec. O X When the engine switch is on and the shift lever is changed other than P position When the folding-up motor is stopped due to overcurrent or pulse malfunction Continued When the fold seat lock motor is stopped due to overcurrent or irregular position information When not becoming the folding mode, even if the retract switch pushes 10 sec. or more in the sitting mode When the engine switch is on or the back door is open, the seat is stopped in the middle position of its operation While pushing retract switch or return switch, the shift lever is changed other than P position While pushing folding switch, the shift lever is changed other than P position 3 times DTC is nothing. The initialization is unnecessary.

-W -Q -V -C -A Power ON Full-power Control This control outputs the maximum voltage to climate controller and fan motor when engine switch is on [MAX COOL Control] Control Contents Operation Condition The engine switch is on After turning on the climate control seat switch, turn it to MAX COOL The climate controller temperature sensor detects 0 °C (32 °F) or more Operation MAX COOL control is performed for approx. 15 minutes [MAX HOT Control] Control Contents Operation Condition The engine switch is on Turn the climate control seat switch to MAX HOT, MID HOT or MIN HOT The thermistor of the seat heater detects 30 °C (86 °F) or more* The MAX HOT control is completed* Operation When the seat heater reaches set temperature, keeps seat temperature TED operates after approx. 10 seconds Then the fan motor operates and TED keeps temperature After the certain time passes, the output voltage to the fan motor is increased every 15 seconds *: The seat heater is not operated when these conditions are met.

-W -Q -V -C -A Fail-safe When the following conditions are met, outputs of blower, Peltier element and seat heater are stopped Fail-safe Control Overcurrent protection control Failure Condition The climate control seat switch is on The current which drives the seat heater or the climate controller exceeds 10 A for 2 seconds. Recovery Condition The climate control seat switch or the engine switch is off Transient voltage drop control ECU power voltage falls 8 V or less for 10 msec. ECU power voltage reaches 10 V or more for 10 msec. Temperature sensor open/short detection control The temp. sensor detected value is 110 °C (230 °F) or more or -40 °C (-40 °F) or less for 8 consecutive seconds The normal value is detected by the temp. sensor for 8 consecutive seconds
