Title

C1233, Replaced Anti-Lock Brake Module Connector

Complaint

The customer states the anti-lock brake system (ABS) light is on.

Cause

Connected a scan tool and found code C1233 – Right Front Wheel Speed Circuit Open Or Shorted. Performed a road test, used the scan tool to monitor live data and found the right front ABS wheel speed sensor signal parameter was not present. Visually inspected the right front ABS wheel speed sensor wiring harness and found no obvious signs of damage. Disconnected the right front ABS wheel speed sensor connector, visually inspected the connector and terminals and found no obvious signs of damage. Sprayed the right front ABS wheel speed sensor with water, used a multimeter to measure the resistance of the sensor and found the measured resistance was within specifications. Performed a visual inspection of the anti-lock brake module and found the connector was damaged.

Correction

Replaced the anti-lock brake module connector, cleared codes, performed a road test and verified the vehicle operated properly. The ABS light did not illuminate and no fault codes returned.

The benefit of R1234yf is simple. The new refrigerant lasts only 11 days in the atmosphere compared to 13 years for R134a. This is why the EPA is requiring R1234yf to be installed in all new systems by 2021. The European Union required the changeover on Jan. 1, 2017.
So, what does this mean for independent shop owners and technicians? Currently, there are approximately 20 million vehicles on the road with R1234yf in the HVAC system. It is not a question of if, but when your shop will have to deal with one of these systems. While working on R1234yf systems is not that different from the R134a variety in operation or theory, identifying the refrigerant and recharging the system has some new twists.
