Circuit/System Test

C0293 01 or C0293 06

1. Ignition OFF, disconnect the harness at the S91 Electric Parking Brake Switch.

2. Test for B+ between the B+ circuit terminal listed below and ground:

* Terminal 4

* Terminal 5

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

K83 Electric Parking Brake Control Module.

瀚慖f greater than the specified range, test the B+ circuit for a short to voltage. If the circuit tests normal, replace the K83 Electric Parking

Brake Control Module.

3. Disconnect the harness at the K83 Electric Parking Brake Control Module.

4. Ignition ON, test for less than 1 V between the following signal circuit terminals at the electric parking brake switch harness connector and

ground:

* Terminal 1

* Terminal 2

* Terminal 3

* Terminal 7

瀚慖f greater than the specified range, test the signal circuit for a short to voltage.

5. Test for infinite resistance between the signal circuits listed below and ground:

* Terminal 1

* Terminal 2

* Terminal 3

* Terminal 7

瀚慖f less than the specified value, test the park brake signal circuit for a short to ground.

6. Test for less than 5 Ohms between the following signal circuit terminals:

* Electric parking brake switch harness terminal 1 and the electric parking brake control module terminal N

* Electric parking brake switch harness terminal 2 and the electric parking brake control module terminal C

* Electric parking brake switch harness terminal 3 and the electric parking brake control module terminal B

* Electric parking brake switch harness terminal 7 and the electric parking brake control module terminal D

瀚慖f greater than the specified range, test the signal circuit for an open/high resistance.

7. If all circuits test normal, test or replace the S91 Electric Parking Brake Switch. If DTC resets, replace the K83 Electric Parking Brake

Control Module.

C0293 08

Remove the EPB fuse and reinstall. Verify DTC C0293 08 is not set.

If DTC C0293 08 is set replace the electric parking brake switch.

Component Testing

1. Ignition OFF, disconnect the harness connector at the electric parking brake switch.

2. Test for infinite resistance between the terminals listed below with the switch in the inactive state:

* B+ terminal 4 and the park brake switch signal terminal 1

* B+ terminal 4 and the park brake switch signal terminal 2

* B+ terminal 5 and the park brake switch signal terminal 1

* B+ terminal 5 and the park brake switch signal terminal 2

* Park brake switch signal terminal 3 and the park brake switch signal terminal 1

* Park brake switch signal terminal 3 and the park brake switch signal terminal 2

* Park brake switch signal terminal 7 and the park brake switch signal terminal 1

* Park brake switch signal terminal 7 and the park brake switch signal terminal 2

瀚慖f less than the specified range, replace the electric parking brake switch.
