Is DTC U0300:00 present in the ABS module or SASM?
Yes If DTC U0300:00 is present in the ABS module, GO to P5 If DTC U0300:00 is present in the SASM, GO to P6 No The concern was caused by a incomplete or improperly programmed BCM, the repair is complete. - P5 CHECK FOR CORRECT ABS (ANTI-LOCK BRAKE SYSTEM) MODULE OPERATION
- Ignition OFF.
- Disconnect ABS module C135 .
- Using a good light source, inspect all disconnected electrical connectors for the following:
- corrosion - install new connector or terminal and clean the module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- spread terminals - install new terminals as necessary
- Connect ABS module C135 . Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new ABS module and HCU. REFER to: Hydraulic Control Unit (HCU) . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. - P6 CHECK FOR CORRECT SASM (STEERING ANGLE SENSOR MODULE) OPERATION
