A: PROCEDURE
1. Activation of malfunction indicator light. 
                                                                  
2. Malfunction indicator light does not come on. 
                                                                  
3. Malfunction indicator light does not go off. 
                                                                  
4. Malfunction indicator light does not blink at a cycle of 3 Hz. 
                                                                  
5. Malfunction indicator light remains blinking at a cycle of 3 Hz.
