ABS/EBD Diagnostic
Trouble Codes (DTCS)
WSS MONITORING
18
1. If the CPU cannot be activated or the CPU fails, the
ABS indicator light comes on, but the DTC is not
memorized.
2. When the same DTC is detected more than once,
the later one is written over the old one.
Therefore, when the same problem is detected
repeatedly, it is memorized as one DTC.
3. The DTCs are indicated in the order they occur.
4. The DTCs are memorized in the EEPROM
(nonvolatile memory) and cannot be canceled by
disconnecting the battery. Most DTCs must be
cleared with the Hi-Scan Pro.
The ABS control module is located on the HECU, and
receives operational power from the 10A ABS fuse.
Two-30A fuses supply B+ power for pump and
solenoid operation. The inputs include the 4 WSS and
brake lamp ON switch. Outputs include the HSP serial
data line, CAN bus, and Instrument Cluster.
Each of the four WSSs is monitored constantly once
vehicle speed exceeds 1.25 mph (2 km/h). Any
condition that causes an out of specification reading
for a wheel sensor will be detected by the HECU and
cause a DTC.
