Anytime there is an electrical issue, first check to ensure the LED light for the Power input (bottom right
corner) of the TCM is turned on when the key switch is in the Off position. If the light is not on:
a. Check the battery disconnect switch to ensure it is turned on.
b. If the battery disconnect switch was already turned on, the TCM may be in ‘Sleep’ mode. Turn the
battery disconnect switch off for 10 seconds and then back on to ‘Wake’ the TCM.
c. Check the 15 amp fuse in slot #10 of the rear fuse panel. Replace this fuse, if necessary.
Next, turn the key switch to the On position and check to see if any of the other lights turn on. If no other
lights turn on, check the 5 amp fuse in slot #9 of the rear fuse panel. If any other lights turn on, you can
start troubleshooting the rest of the TCM functions.
