1 | Did you perform the Door System Diagnostic System Check? | Go to Step 2 | |
2 | Verify that all door locks and switches are inoperative. Do the power door locks operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring System | Go to Step 3 |
3 |
Do the door lock actuators lock and unlock with each command? | Go to Step 4 | Go to Step 7 |
4 | With the scan tool, monitor the door lock and unlock switch parameters while activating the door lock switches to the lock and unlock positions. Do the scan tool parameters change with each switch activation? | Go to Step 14 | Go to Step 5 |
5 | Is the LOCK/MIRROR fuse open? | Go to Step 16 | Go to Step 6 |
6 | Probe the supply side of the LOCK/MIRROR fuse with a test lamp connected to a good ground. Does the test lamp illuminate? | Go to Step 12 | Go to Step 18 |
7 | Is the DR LCK fuse open? | Go to Step 17 | Go to Step 8 |
8 | Probe the supply side of the DR LCK fuse with a test lamp that is connected to a good ground. Does the test lamp illuminate? | Go to Step 9 | Go to Step 18 |
9 | Are both lock and unlock functions inoperative? | Go to Step 19 | Go to Step 10 |
10 |
Did the test lamp illuminate? | Go to Step 15 | Go to Step 20 |

12 | Test the battery positive voltage circuit from the LOCK/MIRROR fuse to the door lock switches for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | Go to Step 11 |
13 | Inspect for poor connections at the I/P fuse block harness connectors. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | Go to Step 14 |
14 | Inspect for poor connections at the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | Go to Step 21 |
15 | Inspect for poor connections at the door lock relay. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | Go to Step 22 |
16 | Repair the short to ground in the battery positive voltage circuit from the LOCK/MIRROR fuse to the I/P fuse block. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | -- |
17 | Repair the short to ground in the battery positive voltage circuit from the BODY fuse to the door lock switches. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | -- |
18 | Repair the open in the battery positive voltage circuit. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 23 | -- |
19 | Repair the open in the door lock relay ground circuit. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you complete the repair ? | Go to Step 23 | -- |
20 | Repair the open or short to ground in the door lock relay control circuit. Refer to Wiring Repairs and Connector Repairs in Wiring Systems. Did you complete the repair? | Go to Step 23 | -- |
21 |
Did you complete the replacement? | Go to Step 23 | -- |
22 | Replace the appropriate door lock relay. Did you complete the repair? | Go to Step 23 | -- |
23 | Operate the system in order to verify the repair. Did you find and correct the condition? | System OK | Go to Step 2 |
