LR ABS wheel-speed sensor (-): O
Is there continuity?
2
INSPECT ABS WHEEL-SPEED SENSOR WIRING HARNESS FOR SHORT TO GROUND
Disconnect the ABS wheel-speed sensor connectors.
Inspect for continuity between the following DSC HU/CM connector terminals
(vehicle harness-side) and body ground:
RF ABS wheel-speed sensor (+): F
RF ABS wheel-speed sensor (-): C
LF ABS wheel-speed sensor (+): AG
LF ABS wheel-speed sensor (-): AJ
RR ABS wheel-speed sensor (+): AA
RR ABS wheel-speed sensor (-): X
LR ABS wheel-speed sensor (+): L
LR ABS wheel-speed sensor (-): O
Is there continuity?
YesRepair or replace the wiring
harness, then go to Step 5.
No Replace the ABS wheel-speed
sensor, then go to Step 5.

INSPECT FOR OPEN CIRCUIT IN ABS WHEEL-SPEED SENSOR WIRING HARNESS
Inspect for continuity between the DSC HU/CM connectors (vehicle harness-
side) and the following vehicle harness-side connector terminals of the ABS
wheel-speed sensors:
RF ABS wheel-speed sensor (+): F—A
RF ABS wheel-speed sensor (-): C—B
LF ABS wheel-speed sensor (+): AG—A
LF ABS wheel-speed sensor (-): AJ—B
RR ABS wheel-speed sensor (+): AA—A
RR ABS wheel-speed sensor (-): X—B
LR ABS wheel-speed sensor (+): L—A
LR ABS wheel-speed sensor (-): O—B
Is there continuity?
YesGo to the next step.
No Repair or replace the wiring
harness, then go to the next step.

INSPECT ABS WHEEL-SPEED SENSOR WIRING HARNESS FOR SHORT TO POWER
SUPPLY
Inspect for voltage between the following DSC HU/CM connector terminals
(vehicle harness-side) and body ground:
RF ABS wheel-speed sensor (+): F
RF ABS wheel-speed sensor (-): C
LF ABS wheel-speed sensor (+): AG
LF ABS wheel-speed sensor (-): AJ
RR ABS wheel-speed sensor (+): AA
RR ABS wheel-speed sensor (-): X
LR ABS wheel-speed sensor (+): L
LR ABS wheel-speed sensor (-): O
Is the voltage 1 V or less ?
YesGo to the next step.
No Repair or replace the wiring
harness, then go to the next step.
5
VERIFY THAT THE SAME DTC IS NOT PRESENT
Reconnect all disconnected connectors.
Clear the DTCs from the memory.
YesRepeat the inspection from Step 1.
If the malfunction recurs, replace
the DSC HU/CM, then go to the
