DTC Descriptor
DTC B0980 00: Transmission Sports Switch Circuit
Short to Ground
Circuit/System Description
The body control module (BCM) controls the.
Conditions for Running the DTC
The DTC can only set only when the output is actively being requested by the
BCM.
Conditions for Setting the DTC
The BCM detects a short to ground, open, or short to voltage in the horn relay
control circuit for approximately 125 milliseconds.
Action Taken When the DTC Sets
The BCM disables the output to the horn relay until the next ignition cycle.
Conditions for Clearing the DTC
• | The DTC clears when the fault is no longer detected. |
• | The current DTC will become history when the request for the output is
removed. |
• | The history DTC will clear after 50 consecutive fault-free ignition

Circuit/System Testing
- Ignition OFF, disconnect the A15 harness connector at the S73 Power/Economy
Switch.
- Ignition ON, test for 12 volts between circuit terminal J-220 and ground.
⇒ | If less than the specified range, test the reference circuit for a short to
ground. If the circuit tests normal, replace the S73 Power/Economy Switch. |
⇒ | If greater than the specified range, test the reference circuit for a short
to voltage. If the circuit tests normal, replace the A15 Body Control Module. |
- If all circuits test normal, test the S73 Power/Economy Switch.
