Yes DIAGNOSE the charging system. Refer to the appropriate section in Group 414 for the procedure.
No GO to J2

J2 TEST BATTERY CONDITION
  • Ignition OFF.
  • Carry out the Battery Condition Test.
    REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).

Did the battery pass the condition test?
Yes If the battery passed the condition test but required a recharge, DIAGNOSE the charging system.
REFER to: Charging System (414-00 Charging System - General Information, Diagnosis and Testing).
CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).
If the battery passed the condition test and did not require a recharge, GO to J3
No INSTALL a new battery.
REFER to: Battery (414-01 Battery, Mounting and Cables, Removal and Installation).
CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).

J3 CHECK THE CHARGING SYSTEM VOLTAGE
  • Start the engine.

Is the voltage between 13 and 15.2 volts?
Yes GO to J4
No DIAGNOSE the charging system. Refer to the appropriate section in Group 414 for the procedure. CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).

J4 CHECK THE SCMJ (POWER FOLD SEAT MODULE) OPERATION
  • Ignition OFF.
  • Disconnect and inspect the SCMJ connectors.
  • Repair:
    • corrosion (install new connector or terminals - clean module pins)
    • damaged or bent pins - install new terminals/pins as necessary
    • pushed-out pins - install new pins as necessary
  • Reconnect the SCMJ connectors. Make sure they seat and latch correctly.
  • Reconnect all previously disconnected connectors.
  • Ignition ON.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SCMJ.
REFER to: Power Fold Seat Module [SCMJ] (501-10C Third Row Seats, Removal and Installation).
TEST the system for normal operation.
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.
