Schematic Reference: Door Lock/Indicator Schematics DEFINITION: This diagnostic should be used to diagnose a failure of the driver door lock actuator (lock, unlock or both). | |||
1 | Did you perform the Power Door System Diagnostic System Check? | Go to Step 2 | |
2 | Actuate all the door lock switches to both the lock and unlock positions. Did the driver door lock and unlock from all of the switches? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Did the passenger door(s) lock and unlock from all of the switches? | Go to Step 4 | |
4 | Did the drivers door lock? | Go to Step 6 | Go to Step 5 |
5 | Did the driver door unlock? | Go to Step 8 | Go to Step 11 |
6 |
Did the test lamp illuminate? | Go to Step 7 | Go to Step 13 |
7 |
Did the data value change from inactive to active when the switch was actuated? | Go to Step 9 | Go to Step 16 |
8 |
Did the test lamp illuminate? | Go to Step 14 | Go to Step 21 |
9 | Connect a test lamp between the battery positive voltage circuit on the coil side of the driver door lock relay at the fuse block and a good ground. Did the test lamp illuminate? | Go to Step 10 | Go to Step 22 |
10 | Connect a test lamp between the battery positive voltage circuit on the switched side of the driver door lock relay at the fuse block and a good ground. Did the test lamp illuminate? | Go to Step 14 | Go to Step 22 |
11 |
Did the test lamp illuminate? | Go to Step 12 | Go to Step 19 |
12 |
Did the test lamp illuminate? | Go to Step 16 | Go to Step 20 |
13 | Test for an open in the driver door unlock relay control circuit between the BCM and the driver door unlock relay. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 17 |
14 | Inspect for poor connections at the driver door unlock 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 25 | Go to Step 18 |
15 | Check for an open in the door unlock control circuit between the BCM and the door lock switches. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 17 |
16 | Inspect for poor connections at the driver door lock actuator. 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 25 | Go to Step 23 |
17 | 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 25 | Go to Step 24 |
18 | Replace the driver door unlock relay. Did you complete the repair? | Go to Step 25 | -- |
19 | Repair the open in the door lock control circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 25 | -- |
20 | Repair the open in the door unlock control circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 25 | -- |
21 | Repair the open in the driver door lock relay ground circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 25 | -- |
22 | Repair the open in the driver door lock relay battery positive voltage circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 25 | -- |
23 | Replace the door lock actuator. Refer to Front Side Door Lock Actuator Replacement . Did you complete the repair? | Go to Step 25 | -- |
24 | Replace the BCM. Refer to Body Control Module Replacement in Body Control System. Did you complete the repair? | Go to Step 25 | -- |
