DTC 2-1

NOTE: Before troubleshooting DTC 2-1, remove the ABS B2 (15 A) fuse in the under-hood fuse/relay box for three seconds to clear the ABS control unit's memory, then test drive the car. If the ABS indicator light stays off, the probability is that the car was driven with the parking brake applied.

If the parking brake has been released, the following items are possible causes. If they are OK, check the ABS control unit connectors for good connection. If not loose or disconnected, substitute a known-good ABS control unit and recheck.
- The parking brake is applied for more than 30 seconds while driving.
- The brake fluid level in the master cylinder is too low.
- GRN/RED wire is shorted between the brake system light and parking brake switch.
- GRN/RED wire is shorted between the brake system light and brake fluid level switch.
- The brake system light is blown.
- GRN/RED wire has an open between the brake system light and the ABS control unit.
