Inhibit Inputs

The Memory Seat ECU (Z146) will not permit movement to the memorized position when the ignition is position 2 unless the handbrake is applied and vehicle speed is below 6 kmh. Vehicles equipped with an automatic transmission must also be in PARK or NEUTRAL for operation to occur.

The ECU monitors the Handbrake Switch (X191) position at terminal C1/13. When the handbrake is in Position 1, the brake is applied and ground is applied to the ECU terminal.

Vehicle speed is monitored by the ECU at terminal 01120 through the speed output signal supplied by the Vehicle Speed Sensor Buffer (Z160).

The ECU monitors gear position through the Starter Inhibit/Reverse Switch (X167). The switch grounds the ECU at terminal C1/24 when the transmission is in PARK or NEUTRAL.
