The second drawing shows which is the Check Engine light. If the bulb is suspected to be burned out, I couldn't find the instructions on disassembling the instrument cluster, but the warranty time is listed at only 0.3 hours and 0.5 hours when not in warranty. The non-warranty times are more realistic. Half an hour is not much time which suggests the job is pretty straight-forward and easy to figure out.
Without having one to look at, the typical procedure would be to find screws to remove the trim panel around the cluster. Some just snap off. Look for four or more screws holding the cluster in place. Remove those, then pull the cluster out. There will be a wiring harness connected to it. There's usually a tab to press while pulling the connector out.
Up through much of the 1990s, most bulbs are pressed into small black sockets, then those sockets are placed in holes on the rear circuit board. Twist those sockets counter-clockwise about 1/8th turn, then pull them out. Pull the bulb out of the socket.
Some manufacturers used the same type of socket but the bulbs were hard-wired into them. For those, you have to buy a new socket with the bulb already in it. There were two different sizes of bulbs and sockets. The common one, often referred to as a number "194", or I call them a "peanut" bulb because that's about their size. Those are commonly used for night-time backlighting. The smaller size is about half the size of the 194.
The Check Engine light gets turned on for about five seconds for a bulb check when the ignition switch is turned on. It is powered by the Engine Computer.
