ACTION:
If you have a BR FLUID LEVEL LOW [C1155] DTC stored:
Check the brake linings for wear. This code is typically stored because of low brake fluid level caused by worn brake linings. With brake application and vehicle movement code C1155 may be detected as fluid level nears the low level line in the brake fluid reservoir.

- If the brake linings are not worn, proceed with diagnosis using standard Warranty Repair Practices.
If you have a PRESS SEN CIRCUIT [C1142] DTC stored:
- Check the adjustment of the Brake Pedal Lamp Switch. Proceed with diagnosis using standard Warranty Repair Practices.
IMPORTANT NOTES:
- If you also have ACC CONT [C1185], ECD MODE MALF [C1A26] or VDC CONTROL UNIT, and ABS/TCS/VDC CIRC [C1A04] codes all stored in combination, they may have been stored as a result of the C1155/C1142 code storing and require no diagnosis or repair.
- The BR FLUID LEVEL LOW [C1155] or PRESS SEN CIRCUIT [C1142] codes may be causing the other three DTCs to store without any actual incidents in the other three circuits.
