PINPOINT TEST G256924p8: B2810; VENT SOLENOID CIRCUIT FAULT
G256924tl 1: CHECK THE VENT SOLENOID SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal. 2. Disconnect the ASU electrical connector, CR91. 3. Disconnect the vent solenoid electrical connector, EC62. 4. Measure the resistance between CR91, pin 10 (YU) and EC62, pin 02 (YU).
^ Is the resistance greater than 5,000 ohms?
- Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924tl 2.

G256924t12: CHECK THE VENT SOLENOID SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Reconnect the battery negative terminal. 2. Measure the resistance between CR91, pin 10 (YU) and GROUND.
^ Is the resistance less than 10,000 ohms?
^ Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924tl 3.

G256924t13: CHECK THE VENT SOLENOID SUPPLY CIRCUIT FOR SHORT TO B+
1. Measure the voltage between CR91, pin 10 (YU) and GROUND.
^ Is the voltage greater than 3 volts?
^ Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
^ No
GO to Pinpoint Test G256924tl 4.
