6.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE ESP LATERAL ACCELERATION SENSOR
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 Lateral Acceler-
ation Sensor Signal circuit.
Is the resistance below 100 kohms?
Yes
>> Repair the ESP Lateral Acceleration Sensor Signal circuit
for a short to ground.
Perform ABS VERIFICATION TEST.
No
>> Go to 7

MEASURE THE RESISTANCE BETWEEN THE ESP LATERAL ACCELERATION SENSOR SIGNAL CIRCUIT
AND THE SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance between the ESP Lateral Acceleration Sensor
Signal circuit and the Sensor Ground circuit in the ESP Lateral Accel-
eration Sensor harness connector.
Is the resistance below 100 kohms?
Yes
>> Repair the ESP Lateral Acceleration Sensor Signal circuit
for a short to the Sensor Ground circuit.
Perform ABS VERIFICATION TEST.
No
>> Replace the ESP Lateral Acceleration Sensor. (Refer to 5 -
