DTC 61 – ABS PUMP MOTOR CIRCUIT
DESCRIPTION
The ABS 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 relay of the module (does not follow these commands).
INSPECTION
STEP
1 1) Check pump motor referring to item "ABS
HYDRAULIC UNIT OPERATION CHECK" in this
section.
Is it in good condition?
2 1) Ignition switch OFF.
2) Disconnect ABS hydraulic unit/control module
connector.
3) Check for proper connection to ABS hydraulic
unit/control module connector at terminal "E20-23".
4) If OK, then measure voltage between terminal
"E20-23" of module connector and body ground.
Is it 10 – 14 V?
3 Measure resistance between terminal
"E20-22" of ABS hydraulic unit/control module
