Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 |
Were communications established? | -- | Go to Step 2 | Go to Step 10 |
2 | Backprobe the DLC using a test lamp from terminal 16 to ground. Did the test lamp light? | -- | Go to Step 4 | Go to Step 3 |
3 | Repair the open in CKT 408 (ORN) between the IP fuse block and the DLC. Will the scan tool communicate with the EBCM? | -- | System OK | Go to Step 4 |
4 | Backprobe the DLC using a test lamp from terminal 16 to terminal 4. Did the test lamp light? | -- | Go to Step 6 | Go to Step 5 |
5 | Repair the open in CKT 441 (BLK) between the DLC and splice pack 4. Will the Scan Tool communicate with the EBCM? | -- | System OK | Go to Step 6 |
6 | Using a J 39200, backprobe the DLC from terminal 12 to the EBCM terminal 5. Does the DMM indicate continuity? | -- | Go to Step 8 | Go to Step 7 |
7 | Repair the open in CKT 396 (TANWHT) or CKT 799 (TAN/WHT) between the DLC and the EBCM. Will the scan tool communicate with the EBCM? | -- | System OK | Go to Step 8 |
8 | Using a J 39200, backprobe the DLC from terminal 12 to terminal 4. Does the DMM indicate continuity? | -- | Go to Step 9 | Go to Step 11 |
9 | Repair the short to ground in CKT 396 (TAN/WHT) or CKT 799 (TAN/WHT) between the DLC and the EBCM. Is the repair complete? | -- | System OK | -- |
10 | Refer to the scan tool instruction manual. Is the problem resolved? | -- | System OK | -- |
11 | Refer to the antilock brakes section of the manual. Is the problem resolved? | -- | System OK | -- |
