(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND1 CIRCUIT)
OK -- Continue to next step.
5. RECONFIRM DTC
(a) Reconnect the skid control ECU connector.
(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related
Diagnostic Procedures/Problem Symptoms Table.
B -- REPLACE BRAKE ACTUATOR ASSEMBLY See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Hydraulic Control Assembly - Antilock Brakes/Service and Repair/Removal
A -- CHECK FOR INTERMITTENT PROBLEMS See: Accessories and Optional Equipment/Antitheft and Alarm

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1232,C1243,C1245:
Acceleration Sensor Stuck Malfunction
DESCRIPTION
The skid control ECU receives signals from the yaw rate and acceleration sensor via the CAN communication system.
The yaw rate sensor has a built-in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2).
If there is a malfunction in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123 (Lost
Communication with Yaw Rate Sensor Module) and U0124 (Lost Communication with Lateral Acceleration Sensor Module) are set.
These DTCs are also output when calibration has not been completed.
