If there is any problem in the CAN bus lines, an incorrect
diagnostic  trouble  code  may  be  set.  Prior  to  this
diagnosis, diagnose the CAN bus lines. (Refer to GROUP
54D, Trouble code diagnosis P.54D-17
).

If the ABS-ECU connector is disconnected or the battery
terminal is disconnected when the ignition switch is ON,
this diagnostic trouble code may be set.

Since the failure information stored in the past is erased
after this diagnosis is carried out, reproduce the state of
malfunction.

ANTI-LOCK BRAKING SYSTEM (ABS) DIAGNOSIS

CIRCUIT OPERATION
The  ABS-ECU  stores  diagnostic  trouble  codes  and  failure
information in the EEPROM*.

NOTE: 

 *:EEPROM (Electrical Erasable and Programable ROM)

DTC SET CONDITIONS
This diagnostic trouble code is set when the failure information
stored  in  the  EEPROM  is  not  reliable.  The  failure  information
stored in the past is not output, and only this diagnostic trouble
code is set.

PROBABLE CAUSES

Disconnection  of  the  ABS-ECU  connector  or  the  battery
terminal when the ignition switch is ON

Loose battery terminal

Abnormality in battery

Damaged wiring harness and connectors

ABS-ECU malfunction
