P1 CHECK THE GSM (GEAR SHIFT MODULE) ROTARY SHIFT KNOB
- INSPECT the rotary shift knob for debris or interference that would prevent it from returning to park.
Was any debris or interference found?

Yes CLEAN the rotary shift knob.

No GO to P2

P2 VERIFY THE BATTERY IS FULLY CHARGED
- NOTE: If necessary connect the battery charger to the vehicle battery to insure a steady battery voltage while performing this test.
  
  VERIFY battery is fully charged before proceeding with this test. REFER to: Battery .
Is the battery fully charged?

P5 CHECK FOR CORRECT GSM (GEAR SHIFT MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all GSM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the GSM connectors. Make sure they seat and latch correctly.

Operate the system and verify the concern is still present

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
