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 G295394t18.
No
GO to Pinpoint Test G295394t19.

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. CLEAR the DTC. TEST the system for normal operation.
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 G295394t20.
No
GO to Pinpoint Test G295394t21.

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. CLEAR the DTC. TEST the system for normal operation.
No
GO to Pinpoint Test G295394t21.

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. CLEAR the DTC. TEST the system for normal operation.
No
INSTALL a new hall effect sensor. (The hall effect sensor is not available separately). 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.
