DTC Descriptor
DTC B0980: Transmission Sport Switch Circuit Short to GroundDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Signal | B0980 | 1 | -- | -- |
Ground | -- | 1 | -- | -- |
Transmission Hold Mode Inoperative | ||||
Circuit/System Description
The transmission hold switch is an input to the instrument panel cluster (IPC). The switch signal circuit is supplied a reference voltage from the IPC. When the hold switch is pressed the reference voltage is closed to ground. When the reference voltage is low the switch is determined to be active.
Conditions for Running the DTC
Ignition voltage is greater than 9.5 V.
Conditions for Setting the DTC
The hold switch signal circuit is low for greater than 60 seconds.
Action Taken When the DTC Sets
The transmission hold mode will be disabled.
Conditions for Clearing the DTC
The current DTC clears when the fault is no longer present.

Circuit/System Verification
Ignition ON, observe the scan tool Hold Switch parameter while pressing and releasing the hold switch. The reading should change between Active and Inactive.
Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the hold switch.
- Test for less than 10 Ω between the ground circuit terminal 2 and ground.
- Ignition ON, verify the scan tool Hold Switch parameter is Inactive.
- Install a 3A fused jumper wire between the signal circuit terminal 1 and the ground circuit terminal 2. Verify the scan tool Hold Switch parameter is Active.
- If all circuits test normal, test or replace the hold switch.
| ⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
| ⇒ | If not the specified value, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the IPC. |
| ⇒ | If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the IPC. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
