DTC C1296: ABS Malfunction [10/2020 - ]: Procedure

1. Clear the DTC.

   Chassis > Brake > Clear DTCs 

2. Turn the ignition switch off.
3. Turn the ignition switch to ON again.
4. Drive the vehicle, accelerate to a speed of 20 km/h (12 mph) or more, and check if the speed sensor DTC (vehicle stability control system DTC) is output.

   Chassis > Brake > Trouble Codes 

   Result

   Result	Proceed to
   Vehicle stability control system DTC (speed sensor or acceleration sensor DTC) is not output	A
   Vehicle stability control system DTC (speed sensor or acceleration sensor DTC) is output	B

   HINT: 

   When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.

Result: 

B 

REPAIR CIRCUIT INDICATED BY OUTPUT CODE (VEHICLE STABILITY CONTROL SYSTEM). Refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2020 - 08/2021]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [08/2021 - ] 

Result: 

A 

See step  2

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Chassis / Four Wheel Drive / Data List.
5. Read the value displayed on the Techstream.

   Chassis > Four Wheel Drive > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   FR Wheel Speed	Front wheel speed sensor RH reading	Min.: 0 km/h (0 mph) Max.: 326 km/h (202 mph)	0 km/h (0 mph): Vehicle stopped	No large fluctuations when driving at a constant speed.
   FL Wheel Speed	Front wheel speed sensor LH reading	Min.: 0 km/h (0 mph) Max.: 326 km/h (202 mph)	0 km/h (0 mph): Vehicle stopped	No large fluctuations when driving at a constant speed.
   RR Wheel Speed	Rear wheel speed sensor RH reading	Min.: 0 km/h (0 mph) Max.: 326 km/h (202 mph)	0 km/h (0 mph): Vehicle stopped	No large fluctuations when driving at a constant speed.
   RL Wheel Speed	Rear wheel speed sensor LH reading	Min.: 0 km/h (0 mph) Max.: 326 km/h (202 mph)	0 km/h (0 mph): Vehicle stopped	No large fluctuations when driving at a constant speed.

See step  3

1. Enter the following menus: Chassis / Four Wheel Drive / Data List.
2. Read the value displayed on the Techstream.

   Chassis > Four Wheel Drive > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Forward and Rearward G	Forward and Rearward G	Min.: -25.10 m/s2 Max.: 24.90 m/s2	Approximately 0 +/-0.13 m/s2 while stationary	Changes in proportion with acceleration during acceleration/deceleration.

   Chassis > Four Wheel Drive > Data List 

   Tester Display
   Forward and Rearward G

   OK

   The yaw rate and acceleration sensor (airbag sensor assembly) output value is normal.
