I have successfully installed an MSM-1 Sound Module and FS-IA10B 10 channel receiver into a Tamiya Scania 770S tractor truck and I’m using a Flysky AFHDS2A 10 channel radio.
I have 40 LED lights installed in various locations and have tested and confirmed all lights and sounds function properly. After testing and completing the build I reassembled the truck for a "test drive”. When I throttle up the radio transmitter, the engine sound starts as normal and all 40 lights and sounds work properly. When I increase the speed, the sound follows correctly and all lights work. When I put it into reverse, then white reverse/back up lights flash for a second and everything turns off and the MSM-1 module flashes a blue light 4 times then turns green again. If I repeat the process it acts the same way again. But, if I put the throttle stick in the reverse position, the sound tries to start/make a sound, the rear lights flask for a second and the MSM-1 blue light flashes 4 times again. Sometimes when I start the system, the engine comes on as if it was throttled up high instead of an idling sound. Meanwhile all the servos and running equipment seem fine.
I’m frustrated with all this as I have triple checked all wires, connection, and grounds. Remember at one point everything worked just fine. By the way, I’m suing a new Zeee Power brand 7.2V 5000Ah NiM battery and the transmitter shows both the TX and RX battery as full.
l would greatly appreciate your assistance as I would love to complete this project.

Re: MSM-1 acting strange
The blue LED always flashes a few times when the processor starts up. This normally only happens when the power supply is applied. But it looks like this also happens when you reverse. I can't say why this is happening yet.
This could be due to a voltage drop, or an interference caused by the motor.
Can you test whether the error occurs when the motor is not connected to the ESC?
Do you happen to have the K-USB-2 data cable? Then we might be able to see something via the diagnostics.
When the processor restarts, it always reads the neutral position of the throttle channel. If this happens while you're still applying throttle on the radio, an incorrect neutral position is read. This is the reason why a throttle signal is sometimes detected even though the stick on the radio is in neutral. However, this effect disappears if the processor doesn't restart.
