PINPOINT TEST G426404p4 : DTC B2828: EVAPORATOR TEMPERATURE SENSOR CIRCUIT TEST

G426404t11 : CHECK THE EVAPORATOR TEMPERATURE SENSOR CIRCUIT FOR OPEN CIRCUIT
1. Disconnect the battery negative terminal.
2. Disconnect the rear climate control module connector RA01.
3. Disconnect the evaporator temperature sensor connector RA10.
4. Measure the resistance between the rear climate control module connector RA01, pin 09 (G) and evaporator temperature sensor connector RA10, pin 01 (G).

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO

G426404t13 : CHECK THE EVAPORATOR TEMPERATURE SENSOR CIRCUIT FOR SHORT TO B+
1. Reconnect the battery negative terminal.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the rear climate control module connector RA01, pin 09 (G) and GROUND.

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
INSTALL a new evaporator temperature sensor. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, INSTALL a new rear climate control module.
