B1960 - Recliner Pot Feedback Circuit Short to Battery

DTC B1960 - Recliner POT Feedback Circuit Short To Battery

B1960-1 - Rerun Self-Test

- Turn ignition switch to RUN.
- Turn ignition switch OFF. These two steps "wake up" the driver seat module.
- Open driver side door. This disables delay accessory function.

NOTE: Seat will move a short distance in each direction during self-test.

- Execute self-test.
- Inspect all circuits under seat. Make sure all potentiometers are connected.
- Clear DTCs.
- Rerun self-test.

Is DTC B1960 still present?

YES G0 to B1960-2.
NO SYSTEM operating normally.

B1960-2 - Check For Additional DTCs

Are DTCs B1952, B1956 and B1964 also present?

YES GO to Pinpoint Test B. B - DTCs B1952, B1956 & B1964 Drvr Seat Pot Short To B+ Or Open
NO GO to B1960-3.

B1960-3 - Test Potentiometer Input

- Using a voltmeter, carefully back probe recline up/down potentiometer input circuit 445 (O/LB) on pin C3-3 of driver seat module connector for voltage.

Is voltage greater than 4.5 volts?

YES GO to B1960-4.
NO REPLACE driver seat module. RETEST system.

B1960-4 - Test Potentiometer

- Disconnect connector from potentiometer.
- Disconnect connector C3 from driver seat module.
- Carefully probe recline up/down potentiometer input circuit 445 (O/LB) on pin C3-3 connector of driver seat module for voltage.

Is voltage greater than 4.5 volts?

YES SERVICE circuit 445 (O/LB) for short to 5 volt supply. RETEST system.
NO GO to B1960-5.

B1960-5 - Test Circuit 445 (O/LB)

- Using an ohmmeter, test for continuity on circuit 445 (O/LB) from pin C3-3 to center pin on potentiometer connector.

Is there continuity?

YES GO to B1960-6.
NO SERVICE circuit for open circuit. RETEST system.

B1960-6 - Test Potentiometer Common

- Reconnect connector C3 to driver seat module.
- Test circuit 445 (O/LB) at potentiometer for continuity with ground.

Is there continuity?

YES REPLACE potentiometer. RETEST system.
NO SERVICE circuit 445 (O/LB) for open circuit. RETEST system.
