1 | Did you perform the Diagnostic System Check - Vehicle? | -- | Go to Step 2 | Go to Diagnostic System Check - Vehicle in Vehicle DTC Information |
2 |
Do the Door Lock Switch Data parameters change state properly with each door lock switch activation? | -- | Go to Step 3 | Go to Step 4 |
3 | Did all the door lock actuators lock and unlock with both switches? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 6 |
4 |
Does the test lamp illuminate? | -- | Go to Step 5 | Go to Step 12 |
5 | With a DMM, measure the available voltage at the inoperative door lock switch signal circuit. Is the measured voltage within the specified range? | 10-12 V | Go to Step 9 | Go to Step 7 |
6 |
Did the test lamp illuminate with each scan tool lock and unlock command? | -- | Go to Step 10 | Go to Step 8 |
7 | Test for an open in the door lock switch signal circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 16 | Go to Step 11 |
8 | Test for an open in the door lock actuator lock and unlock control circuits. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 16 | Go to Step 11 |
9 | Inspect for poor connections at the door lock switch. 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 16 | Go to Step 13 |
10 | Inspect for poor connections at the 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 16 | Go to Step 14 |
11 | Inspect for poor connections at the body control module (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 16 | Go to Step 15 |
12 | Repair the open in the door lock switch ground circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | -- | Go to Step 16 | -- |
13 | Replace the door lock switch. Refer to Door Lock Switch Replacement . Did you complete the repair? | -- | Go to Step 16 | -- |
14 | Replace the door lock actuator. Did you complete the repair? | -- | Go to Step 16 | -- |
15 | Replace the BCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the repair? | -- | Go to Step 16 | -- |
16 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
