瀚慖f greater than the specified range, test the signal circuit terminal 4 for a short to voltage. If the circuit tests normal, replace the trailer

brake control module.

6. Install a 3 A fused jumper wire between the signal circuit terminal 4 and the 5 V reference circuit terminal 3. Verify the scan tool Manual

Apply Switch parameter is greater than 90 percent.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the trailer brake control module.

7. Verify the scan tool Redundant Manual Apply Switch parameter is greater than 90 percent.

瀚慖f less than the specified range, test the signal circuit terminal 5 for a short to voltage. If the circuit tests normal, replace the trailer brake

control module.

8. Install a 3 A fused jumper wire between the signal circuit terminal 5 and the 5 V reference circuit terminal 3. Verify the scan tool Redundant

Manual Apply Switch parameter is less than 2 percent.

瀚慖f greater than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal,

replace the trailer brake control module.

9. Ignition ON, test for 4.8-5.2 V between the signal circuit terminal 6 and ground.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the trailer brake control module.

瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the trailer brake control

module.

10. If all circuits test normal, test or replace the trailer brake controller switch panel.
