Circuit Description
The body control module (BCM) controls the automatic transmission (A/T) shift lock control solenoid ground circuit and monitors the voltage of the ground control circuit.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2713 Gearshift Lock Circuit High
Conditions for Running the DTC
The controlled ground circuit of the A/T shift lock control solenoid must be ON.
Conditions for Setting the DTC
| • | The BCM detects the controlled ground circuit voltage is approximately equal to battery voltage in the ON state. |
| • | The condition above must be present for more than 0.3 second. |
| • | This DTC will be set after 20 seconds due to possible false failures. |
Action Taken When the DTC Sets
The BCM stores DTC B2713 in memory.
Conditions for Clearing the DTC
| • | The BCM determines that the controlled ground circuit of the A/T shift lock control solenoid is no longer shorted to battery voltage. |
| • | A history DTC B2713 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present. |
| • | A scan tool may be used to clear the DTC. |
Diagnostic Aids
| • | If DTC B2713 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent Conditions and Poor Connections . |
| • | The following conditions may cause an intermittent malfunction to occur: |
| - | An intermittent short to battery voltage in the controlled ground circuit of the A/T shift lock control solenoid |
| - | The A/T shift lock control solenoid coil is shorted to battery voltage internally. |
| - | The BCM is shorted to battery internally. |
