Overview
Below you will find the Brake Set Alert Troubleshooting guide. In this guide, you'll find symptoms, possible faults and signal information to assist you.
Symptom | Possible Fault | Signal Information |
LED does not turn ON | Check fuses | |
LED does not turn ON | Check ignition circuit | 12V with ignition ON |
LED does not turn ON | Check LED circuit | Black wire = +Vbatt, Red wire = LED trigger (ground or open), Green wire = Green LED trigger (ground or open) |
LED does not turn ON | Check TCM wire is not grounded when the speed is lower than 7mph | TCM wire 105 is open circuit<7mph, ground> 7mph |
Symptom | Possible Fault | Signal Information |
LED is Turning RED | Check the door correctly presses the door switches | Door switches have +12V when pressed and Open circuit when released |
LED is Turning RED | Check LED circuit | Black wire = +12V, Red wire = Red LED trigger ground |
LED is Turning RED | Check the pressure sensor | Closed circuit with 90psi of pressure |
LED is Turning RED | Check TCM wire is not grounded when the speed is lower than 7mph | TCM wire 105 is open circuit<7mph, ground> 7mph |
Symptom | Possible Fault | Signal Information |
LED is turning green | Check the door switches are not stuck pressed or short circuited | Door switches have +12V when pressed and Open circuit when released |
LED is turning green | Check LED circuit | Black wire = +12v, Green wire = Green LED trigger ground |
LED is turning green | Check the pressure sensor | Closed circuit with 90psi of pressure |
LED is turning green | Check TCM wire is not grounded when the speed is lower than 7mph | TCM wire 105 is open circuit<7mph, ground> 7mph |
Symptom | Possible Fault | Signal Information |
LED is OFF | Check LED circuit | Black wire = +12v |
LED is OFF | Check TCM wire is not grounded when the speed is lower than 7mph | TCM wire 105 is open circuit<7mph, ground> 7mph |
Symptom | Possible Fault | Signal Information |
