B2736; PEDAL TRAVEL SENSOR CIRCUIT FAILURE

G307559t53: CHECK THE PEDAL TRAVEL SENSOR SUPPLY VOLTAGE
1. Disconnect the brake pedal travel sensor electrical connector EC10.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between EC10, pin 01 (G) and GROUND.
^ Is the voltage less than 10 volts?
-> Yes
-> No

G307559t54: CHECK THE PEDAL TRAVEL SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the resistance between EC10, pin 01 (G) and EC30, pin 26 (G).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G307559t55: CHECK THE PEDAL TRAVEL SENSOR SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC10, pin 01 (G) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
Contact dealer technical support for advice on possible ABS/DSC module failure.

G307559t56: CHECK THE PEDAL TRAVEL SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between EC10, pin 02 (B) and EC30, pin 24 (B).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G307559t57: CHECK THE PEDAL TRAVEL SENSOR GROUND SUPPLY CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Reconnect the ABS/DSC module electrical connector EC30.
3. Turn the ignition switch to the ON position.
4. Measure the resistance between EC10, pin 02 (B) and GROUND.
^ Is the resistance greater than 5 ohms?
-> Yes
Contact dealer technical support for advice on possible ABS/DSC module failure.
-> No

G307559t58: CHECK THE PEDAL TRAVEL SENSOR GROUND CIRCUIT FOR SHORT TO B+
1. Measure the voltage between EC10, pin 02 (B) and GROUND.
^ Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G307559t59: CHECK THE PEDAL TRAVEL SENSOR SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the resistance between EC10, pin 03 (U) and EC30, pin 40 (U).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G307559t60: CHECK THE PEDAL TRAVEL SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC10, pin 03 (U) and GROUND.
^ Is the resistance less than 10,000 ohms?
- Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G307559t61: CHECK THE PEDAL TRAVEL SENSOR SIGNAL SIGNAL CIRCUIT FOR SHORT TO B+
1. Measure the voltage between EC10, pin 03 (U) and GROUND.
^ Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
Contact dealer technical support for advice on possible active booster failure. TEST the system for normal operation. if the DTC is repeated, contact dealer technical support for advice on possible ABS/DSC module failure.
