Operation
Two hydraulic cylinders actuated by oil from an electric-motor driven hydraulic pump are used for raising and lowering the top.

Switch 181 for operating the top is supplied from fuse 12 via red 29-pole connector 152B and 10-pole connector 98.

When the top is being lowered, current flows from pin 2 on the switch to relay 278, which is energized. The relay coil is earthed across switch 43 for the handbrake warning lamp, and the handbrake must therefore be applied before the top can be operated.

Motor 273 of the hydraulic pump (P) is now supplied across the relay contacts from battery land fuse 290 (25 A). The motor is earthed through the second relay (277) which is de-energized.

To raise the top, the direction of rotation of the motor is reversed, since relay 277 is energized instead, and relay 278 is de-energized.

For a complete description of the wiring for the lighting of switch 181 on cars for the US and CA markets and 1989 model for JP, see also the section entitled "Lighting systems, Lighting for controls - US, CA and 1989 for JP".

Fault-tracing hints
The top can be operated when the ignition switch is in the drive position and the handbrake is applied.

1. Check fuse 12 and check that the supply to it is live.
2. Check that the relays for raising and lowering the top perform correctly.
3. Check that the relays are energized at terminal 87 and that the hydraulic pump motor is energized when the switch is actuated.
4. Check the connectors, cable harnesses and earth connections.
