2004 MITSUBISHI ENDEAVOR Abs sensor

between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the TCL/ASC electronic control unit
(TCL/ASC-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The TCL/ASC-ECU monitors the signals from each ABS sensor while the vehicle
is being driven. If any faults below are found in these sensor signals, the ECU will
set the relevant diagnostic trouble code.
Missing sensor signal Sensor signal, which will not be created under normal operation Significant difference among the ABS sensor signals
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Malfunction of the ABS sensor or ABS rotor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to "HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
.
