Diagnostic Aids

By manipulating the harnesses at the various connectors it is often possible to isolate the cause of the circuit interruption. This harness can then be removed and repaired. Inspect for any damage to the harness which could cause an intermittent open or short to ground or backed out terminals at the instrument cluster connectors, broken connector locks, improperly formed or damaged terminals. The multimeter allows continuity of the wiring harness circuit 1061 to be checked.

  1. Install a scan tool.
  2. Turn the ignition ON, with the engine OFF.
  3. With the scan tool, observe the ABS Data display.
Does the Tech 2 display ABS information?
Go to Step 3  Go to Scan Tool Does Not Communicate with UART Device

  1. Turn the ignition OFF.
  2. Remove the instrument cluster. Refer to Instrument Panel Cluster (IPC) Replacement .
  3. Disconnect the electronic brake control module (EBCM).
  4. Check continuity of the universal asynchronous receiver transmitter (UART) circuit between the EBCM and the instrument panel (I/P). Refer to Circuit Testing .
Is continuity present?
Go to Step 4  Go to Step 6 
4 Check the UART circuit between the EBCM and the I/P for a short to ground. Refer to Circuit Testing
Is a short present?
Go to Step 7  Go to Step 5 
5 Check the UART circuit between the EBCM and the I/P for a short to voltage. Refer to Circuit Testing .
Is a short present?
Go to Step 8  Go to Step 9 
6 Repair the open or high resistance in the ground in the UART circuit between the EBCM and the I/P. Refer to Wiring Repairs in Wiring Systems.
Did you complete the repair?
Go to Step 9  -
7 Repair the short to ground in the ground in the UART circuit between the EBCM and the I/P. Refer to Wiring Repairs in Wiring Systems.
Did you complete the repair?
Go to Step 9  -
8 Repair the short to voltage in the ground in the UART circuit between the EBCM and the I/P. Refer to Wiring Repairs in Wiring Systems.
Did you complete the repair?

  1. Use the scan tool in order to clear the DTCs.
  2. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
Does the DTC reset?
Go to Step 2  System OK
