Warning: The center mounting block contains parts that are sensitive to the level of static electricity that builds up on human skin. With the harness connector disconnected, loose contacts are free to conduct static electricity to these parts, rendering them inoperable or even damaging them. Damage may not be noticeable and not immediately apparent Expensive repairs can be avoided by following these basic rules:
- A) Hold the ECU only by the body: do not touch the contacts of the unit with your fingers or tools.
- b) When working on the ECU, ground yourself from time to time by touching metal objects such as unpainted water pipes. This will allow the static electricity to drain from your body.
- V) Do not leave the ECU disconnected longer than necessary for operation.
Removing
1. Disconnect the negative battery terminal.
2. To get to the connectors on the bottom of the unit, remove the cover from the bottom of the instrument panel on the driver's side.
3. Disconnect all plugs from the multi-pin connector on the back bottom side of the center mounting block. Each multi-pin plug is different in shape, so it can only be installed in the corresponding socket. However, we recommend labeling each plug.
4. Turn away bolts of fastening of the main tire of grounding to a partition of a motor compartment behind a panel of devices. Record the location of each of the ground wires.
5. Working in the engine compartment, unscrew the screws and remove the additional relay holder.
6. Remove the cover from the fuses on the central mounting block.
7. Turn away two screws and two nuts of fastening of the block to a partition of a motor compartment.
8. Pull the block forward and up, then unscrew the wire terminals and disconnect the plugs. Write down their location as you remove them.
9. Remove the central mounting block from the engine compartment.
