TRAILER BRAKE PROBLEM CHECK | (a)
Immediately after turning the ignition switch to ON, check the manual
trailer brake output slider (trailer brake control switch) operation
condition. OK: Immediately
after turning the ignition switch to ON, the manual trailer brake output
slider (trailer brake control switch) does not operate continuously for
1 minute or more. | OK |
