1.
Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused
by interference from other electrical systems, and mechanical or chemical damage.
2.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.
3.
Has a problem been found?
YES
▶
Repair as necessary and then go to "Verification Of Vehicle Repair" procedure.
NO
▶
Go to "Power Circuit Inspection" procedure.

Is the measured voltage within specifications?
YES
▶
Go to "Signal Circuit Inspection" procedure.
NO
▶
Check for open or short to GND in wheel speed sensor harness(FL) between terminal "1" of the wheel speed
sensor(FL) harness connector and terminal of the HECU harness connector. Repair as necessary and then go to
"Verification Of Vehicle Repair" procedure.
▶
If OK, Substitute with a known-good HECU and check for proper operation. If problem is corrected, replace HECU
and then go to "Verification Of Vehicle Repair" procedure.

GENERAL DESCRIPTION
E511D3E6
Refer to DTC C1200.
DTC DESCRIPTION
EEC18A75
The ABS ECU monitors the wheel speed sensor signal continuously. This code is set when an abnormal signal due to air
gap problem or an abnormal speed change ratio are detected at the vehicle speed between 10 km/h to 80 km/h. Warning
lamp is turned OFF unless additional faults are detected when the IG KEY is turned ON again, and wheel speed is more
than 12 Km/h.
DTC DETECTING CONDITION
E11689A9
Item
Detecting Condition
Possible cause
DTC Strategy
• Signal monitoring
Monitoring
Period
• The monitoring is active from 10 km/h to
80 km/h and if no ABS-control is active at a
front wheel and a rear wheel.
Case1
Enable
Conditions
• Every time, if a gap in the wheel speed sensor
signal occurs cyclically with one wheel rotation,
a fault counter is increased by one. If the fault
counter exceeds its limit of 6, a wheel specific
fault is stored in the EEPROM.
Monitoring
Period
• Continuous
Case2
Enable
Conditions
• If following interference and signal disturbance
is detected, a failure is set after 10 s.
non-plausible high frequency received.
non-plausible high wheel acceleration.
non-plausible high wheel jurk.
non-plausible delta T and edges at low speed.
Fail Safe
Refer to DTC C1200.
• Improper installation of wheel
speed sensor
• Abnormal Rotor and wheel
bearing
• Inoperative Wheel speed
sensor
• Inoperative HECU
