1140-ESP BRAKE PRESSURE SENSOR 1 CIRCUIT (CONTINUED)
6.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE ESP BRAKE PRESSURE SENSOR 1
SIGNAL CIRCUIT
Turn the ignition off.
Disconnect the CAB harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the ESP Brake Pressure
Sensor 1 Signal circuit.
Is the resistance below 100k ohms?
Yes >> Repair the ESP Brake Pressure Sensor 1 Signal circuit for
a short to ground.
Perform ABS VERIFICATION TEST.
No >> Go to 7
7.
MEASURE THE RESISTANCE BETWEEN THE ESP BRAKE PRESSURE SENSOR 1 SIGNAL CIRCUIT AND
THE SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance between the ESP Brake Pressure Sensor 1
Signal circuit and the Sensor Ground circuit in the ESP Brake Pres-
sure Sensor 1 harness connector.
Is the resistance below 100k ohms?
Yes >> Repair the ESP Brake Pressure Sensor 1 Signal circuit for
a short to the Sensor Ground circuit.
Perform ABS VERIFICATION TEST.
No >> Replace the ESP Brake Pressure Sensor 1. (Refer to 5 -
BRAKES/ELECTRICAL/PRESSURE
REMOVAL).
Perform ABS VERIFICATION TEST.
8.
CHECK THE ESP BRAKE PRESSURE SENSOR 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE
Turn the ignition off.
Disconnect the CAB harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the 5-Volt Supply circuit at the ESP Brake
Pressure Sensor 1 harness connector.
Is the voltage below 1.0 volt?
Yes >> Go to 9
No >> Repair the 5-Volt Supply circuit for a short to voltage.
Perform ABS VERIFICATION TEST.
