Checking cables and sensors
Check cable for power supply between wheel sensor connector:
Diagnostic trouble code (DTC) ABS-0030 Left rear wheel sensor
#1 and control module #6
Diagnostic trouble code (DTC) ABS-0040 Right rear wheel sensor
#1 and control module #22
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, voltage should be approximately 1 V under Ubat measured on the ground terminal.
Check signal cable between wheel sensor connector:
Diagnostic trouble code (DTC) ABS-0030 Left rear wheel sensor
#2 and control module #5
Diagnostic trouble code (DTC) ABS-0040 Right rear wheel sensor
#2 and control module #23
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 sensor (with the sensor connected) by switching on ignition and measuring signal from sensor between breakout box:
Diagnostic trouble code (DTC) ABS-0030 Left rear wheel sensor
#1 and ground terminal.
Diagnostic trouble code (DTC) ABS-0040 Right rear wheel sensor
#23 and ground terminal.
Voltage should vary approximately 1 V when the pulse wheel is rotating. Replace wheel sensor if voltage is faulty.
Remedy as necessary.
