Pinpoint Test E: Check The Left-Hand Rear WSS And Circuits

NOTE: Check connectors and pins for damage/corrosion. See VISUAL INSPECTION . NOTE: Check the WSS ring condition, wheel bearing, etc. Before beginning pinpoint test, refer to the VISUAL INSPECTION .
TEST CONDITIONS	DETAILS/RESULTS/ACTIONS
E1: CHECK THE WSS OUTPUT	Disconnect ABS sensor connector, LA02. Connect a multimeter set to read alternating current volts (AC volts) between pins 1 and 2 of the sensor. Spin the wheel by hand and check the meter display. Does the sensor generate voltage? Yes Go to E2. No If the WSS ring is in good condition, install a new WSS. Refer to REAR WHEEL SPEED SENSOR .
E2: CHECK THE WSS SIGNAL CIRCUIT CONTINUITY	Make sure the ignition is off. Disconnect the ABS module connector, LF27. Measure the resistance between LF27, pin 21 and LA02, pin 01. Is the resistance less than 5 ohms? Yes Go to E3. No Repair the high resistance circuit. Refer to SYSTEM WIRING DIAGRAMS for XJR or SYSTEM WIRING DIAGRAMS for XJ8. Clear the DTC and check for normal operation.
E3: CHECK THE WSS RETURN CIRCUIT CONTINUITY	Measure the resistance between LF27, pin 22 and LA02, pin 02. Is the resistance less than 5 ohms? Yes The WSS circuits are OK. Check for DTCs indicating a possible module failure. No Repair the high resistance circuit. Refer to SYSTEM WIRING DIAGRAMS for XJR or SYSTEM WIRING DIAGRAMS for XJ8. Clear the DTC and check for normal operation.
