Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
Ignition Switch Key Capture Solenoid Control (Ignition Lock Cylinder Solenoid) | B3601 02 | 1 | -- | -- |
Ignition Switch Key Capture Solenoid Ground (Ignition Lock Cylinder Solenoid) | -- | 1 | -- | -- |
1. Ignition cannot be turned ON or OFF |
The body control module (BCM) applies voltage to the key capture solenoid (ignition lock cylinder solenoid) under specific conditions to allow the ignition to be turned ON or OFF.
This DTC runs in all ignition modes
The BCM detects a voltage level on the control circuit less than 2 volts when the key capture solenoid (ignition lock cylinder solenoid) is commanded ON.
The key capture solenoid (ignition lock cylinder solenoid) output is disabled.
• | A current DTC will clear when the condition for setting the DTC is no longer present. |
• | A history DTC will clear after 40 malfunction-free ignition cycles. |

Control Module References for scan tool information
With the key in the vehicle, observe the scan tool Key Capture Solenoid Command parameter while cycling the ignition switch ON and OFF. The parameter should cycle between On and Off.
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp is always ON, test the control circuit for short to voltage. If the circuit tests normal, replace the BCM. |
⇒ | If the test lamp is always OFF, test the control circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If greater than the specified value, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If the test lamp is always ON, test the control circuit for a short to ground. If circuit tests normal, replace the park switch (transmission control replacement). |
⇒ | If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If circuit tests normal, replace the park switch (transmission control replacement). |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
