terminal side)
[D]: ABS control module connector (viewed from
terminal side)
DTC Detecting Condition
The ABS (ESP®) control module monitors the voltage at monitor terminal of pump motor circuit constantly with the
ignition switch turned ON. It sets this DTC when the voltage at the monitor terminal does not become high / low
according to ON/OFF commands to the motor driver (transistor) of the module (does not follow these commands).
DTC Troubleshooting
Step
1 Was "ABS Check" performed?
2 1) Turn Ignition switch to OFF position.
2) Disconnect ABS (ESP®) control module connector.
3) Check for proper connection to ABS (ESP®) control
module connector at terminal "E03-1" (or "E53-32").
4) If OK, then measure voltage between terminal "E03-1"
(or "E53-32") of module connector and body ground.
Is it 10 – 14 V?
3 Measure resistance between terminal "E03-13" and "E03-
26" (or "E53-16" and "E53-47") of ABS (ESP®) hydraulic unit
/ control module connector and vehicle body ground.
Is resistance less than 1
