No wheel speed sensor output signal.
• Malfunction of wheel speed sensor
• Improper installation of wheel speed sensor
• Malfunction of rotor (excitor)
• Malfunction of wiring harness or connector
• Malfunction of HECU
DTC No. C1101, C1102 Voltage out of range
(Low and over voltage)
Probable cause
The voltage of the HECU power supply drops lower than or
rises higher than the specified value. If the voltagereturns to
the specified value, this code is no longer output.
• Malfunction of wiring harness or connector
• Malfunction of HECU.
If battery voltage drops or rises during inspection, this code will be output as well. If the voltage returns to the standard
value, the code is no longer output. Before carrying out the followinginspection, check the battery level, and refill if
necessary.
DTC No. C1604 HECU Hardware
(EEPROM and ECU failure)
Probable cause
The HECU always monitors the solenoid valve drive circuit. It
determines that there is an open or short-circuit in the
solenoid coil or in a harness even if no current flows in the
solenoidor through the HECU.
• Malfunction of wiring harness
• Malfunction of HECU
