Parking Brake - VIN Range: G00442->G45170

PINPOINT TEST G295394p5 : DTC C1799; HALL EFFECT SENSOR FAILURE
G295394t17: CHECK THE HALL EFFECT SENSOR POWER SUPPLY
1. Disconnect the EPB motor electrical connector, CV07.
2. Measure the voltage between CV07, pin 03 (Y) and GROUND.
^ Is the voltage less than 3 volts?
Yes: GO to Pinpoint Test G295394tl 8.
No: GO to Pinpoint Test G295394tl 9.

G295394t18: CHECK THE HALL EFFECT SENSOR POWER SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the EPB control module electrical connector, CR32.
3. Measure the resistance between CV07, pin 03 (Y) and CR32, pin 10 (Y).
^ Is the resistance greater than 5 ohms?
Yes: REPAIR the high resistance circuit.
No: GO to Pinpoint Test G295394t19.

G295394t19: CHECK THE HALL EFFECT SENSOR SIGNAL GROUND
1. Reconnect the battery negative terminal.
2. Measure the resistance between CV07, pin 05 (WU) and GROUND.
^ Is the resistance greater than 5 ohms?
Yes: GO to Pinpoint Test G295394t2O.
No: GO to Pinpoint Test G295394t2l.

G295394t2O: CHECK THE HALL EFFECT SENSOR SIGNAL GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between CV07, pin 05 (WLI) and CR32, pin 12 (WLI).
^ Is the resistance greater than 5 ohms?
Yes: REPAIR the high resistance circuit.
No: GO to Pinpoint Test G295394t2l.

G295394t2l : CHECK THE HALL EFFECT SENSOR INPUT CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between CV07, pin 04 (YB) and CR32, pin 04 (YB).
^ Is the resistance greater than 5 ohms?
Yes: REPAIR the high resistance circuit.
No: INSTALL a new hall effect sensor. (The hall effect sensor is not available separately). Parking Brake Release Actuator - VIN Range: G00442->G34527 (70.35.451 CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, contact dealer technical support for advice on possible EPB module failure.
