Checking wiring and sensors
Check the wiring for power supply between the relevant wheel sensor:
Diagnostic Trouble Code (DTC) ABS-0010 Front left wheel sensor
terminal #2 and control module terminal #1
Diagnostic Trouble Code (DTC) ABS-0020 Front right wheel sensor
terminal #1 and control module terminal #20
for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
HINT: With the ignition on, the voltage should be approximately 1 V under Ubat measured at the ground terminal.
Check the signal cables between the relevant wheel sensor:
Diagnostic Trouble Code (DTC) ABS-0010 Front left wheel sensor
terminal #2 and control module terminal #1
Diagnostic Trouble Code (DTC) ABS-0020 Front right wheel sensor
terminal #2 and control module terminal #19
for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Check the sensor (with the sensor connected): Switch on the ignition and measure the signal from the sensor between the breakout box:
Diagnostic Trouble Code (DTC) ABS-0010 Front left wheel sensor
terminal #1 and ground terminal.
Diagnostic Trouble Code (DTC) ABS-0020 Front right wheel sensor
terminal #19 and ground terminal.
The voltage should vary by approximately 1 V when the pulse wheel is rotating. Replace the wheel sensor if the voltage is faulty.
Remedy as necessary.
