For 1990-2009 cars

### Circuit Description

When the TCS is enabled, the TRAC LED request from the EBTCM to the BCM (circuit 832) is at battery voltage and the BCM grounds circuit 1660. This action turns the TRAC LED on, indicating that the TCS is available.

When the driver disables the TCS by depressing the TRAC switch, the EBTCM grounds circuit 832. In response, the BCM turns the LED off by removing the ground on circuit 1660.

### Conditions for setting the DTC

DTC B0828 will set:

• | If the driver depresses the TRAC switch with the ignition in the RUN position and circuit 1660 is open or shorted to voltage.

| Important: The EBTCM does not test circuit 832 for a malfunction.

| Important: DTC B0827 will not illuminate a telltale.

• | Output from the BCM is on.

### Diagnostic Aids

Inspect the wiring, the components, and the connector for the following conditions:

• | Proper connection

• | Backed-out terminals

• | Broken connector locks

• | Corrosion in the connectors/terminals

• | Burned, chafed or pinched wires

• | A broken wire inside the insulation

• | Loose components
