The rotational speed of the torque converter and the transmission shaft should be equal when the torque converter lockup engine engages. If the torque converter RPM and the transmission input shaft RPM are not equal, the required 1:1 ratio has not been achieved, and the P0741 diagnostic trouble code will be set by the PCM as an indication that the torque converter clutch circuit is out of performance or stuck off.
The circuit feed should measure 12 volts. An improper voltage reading could point to damaged wiring. Check connectors, inspect the ground circuit, and look for any frayed, cut, or loose wiring. You should also measure the resistance of the heater circuit.

If your vehicle has stored a code P2300, accompanied by a malfunction indicator lamp (MIL), it means that the powertrain control module (PCM) has detected an unexpectedly low voltage condition in the primary control circuit of the ignition coil designated with the letter A. Refer to a manufacturer specific guide to determine which is the "A" circuit for your particular application.
Primary circuits of the ignition coil are the wires which supply battery voltage to the coil. Voltage is delivered through fuses, relays, and various other sources. The high-energy ignition boot, spark plug boot, or spark plug wire is NOT considered a primary circuit.
Use the DVOM to test voltage and ground circuits at the ignition coil in question. If no voltage is detected, check the system relay and related fuses. Replace defective relays and/or blown (or otherwise defective) fuses as required.
If voltage and ground are detected at the coil, test the corresponding ground circuit at the PCM connector with the engine running. If ground pulse is detected there, suspect an open circuit between the coil in question and the PCM. If no ground pulse is discovered there, suspect a defective PCM, or a programming error.
Something to note about the C1201 code is that it can often be paired with codes C1198-C1200, which specify the actual issue with the ABS inlet valve in the left front wheel. While C1201 reports when the inlet valve has a circuit short, code C1198 tells you that there has been a circuit failure. C1199 informs you when the circuit is open with the inlet valve and C1200 indicates that the circuit is shorted to the battery. All of these issues will all cause the same symptoms, but each may require different methods of repair.
A C1201 code is almost always caused by a poor electrical connection or a wiring harness that is damaged physically. These components control the normal operating voltage levels, so anytime there is a disruption to the circuit, the ABS module will pick up on it since it is continuously tracking its performance. Another possible cause of the C1201 code is a stuck or defective solenoid pump that can disrupt the braking mechanism of the ABS and the traction control system. This also applies to codes C1198-C1200, as they can be triggered by a poor or intermittent connection at the ABS module as well.
Since the cause of the C1201 code is the ABS inlet valve, repairs will consist of replacing the old valve with a new one. This can be difficult to perform sometimes as the inlet valve is usually integrated into the ABS assembly. This also applies to C0040 and related codes if the wheel speed sensor is in question since it typically is only replaced and not repaired. For C1095 and related codes, more often than not, it requires replacing the hydraulic pump unit. However, if the issue lies with C1238 and related codes, it will require looking at the wiring harnesses and circuit systems leading from the alternator and battery to the ECU. This is a much more meticulous process and not recommended for your average car enthusiast to attempt. This is why it is recommended to contact a technician with related experience repairing these types of circuits so that you can be sure of the repair.
Check the battery and the terminal cable connections. If they look really corroded, you need to clean the battery posts and cable connectors or replace the cables and try to start the engine. Also check the starter. The solenoid attached to the top of the starter can fail, as well as the components inside. Replace starter solenoid, starter contacts, starter assembly or repair starter circuit as required.

Abstract:
This tutorial will walk the audience through an entire loudspeaker design as well as introducing the basic concepts of loudspeakers. Equivalent circuits, impedance, and Thiele-Small Parameters are shown. Inherent driver nonlinearities are explained. The effects of modal behavior and cone breakup are demonstrated. Closed Box and Ported Box systems are analyzed and several design examples are meticulously worked through, both with hand calculations and using CAD. Passive Radiator, Band Pass, and Transmission Line systems are also shown. Issues with multiple drivers and cabinet construction are discussed. Directivity and diffraction effects are illustrated. Crossover network design fundamentals are presented, with a specific design example for the previously shown ported enclosure design.
