DTC B113E:12 [POWER LIFTGATE (PLG) CONTROL MODULE]

id0902o8047100

Description	Power liftgate (PLG) rear switch circuit malfunction
Detection condition	• Power liftgate (PLG) control module detects a short to power supply in the power liftgate (PLG) rear switch circuit.
Fail-safe	• Stops the power liftgate (PLG) system operation.
Possible cause	• Power liftgate (PLG) rear switch connector or terminal malfunction • Power liftgate (PLG) rear switch malfunction • Power liftgate (PLG) control module connector or terminal malfunction • Short to power supply in wiring harness between power liftgate (PLG) rear switch terminal C and power liftgate (PLG) control module terminal 1AF • Power liftgate (PLG) control module malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	INSPECT POWER LIFTGATE (PLG) REAR SWITCH CONNECTOR CONDITION • Switch the ignition off. • Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Disconnect the power liftgate (PLG) rear switch connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 5.
2	INSPECT POWER LIFTGATE (PLG) REAR SWITCH • Inspect the power liftgate (PLG) rear switch. (See POWER LIFTGATE (PLG) REAR SWITCH INSPECTION.) • Is the power liftgate (PLG) rear switch normal?	Yes	Go to the next step.
2		No	Replace the power liftgate (PLG) rear switch, then go to Step 5. (See POWER LIFTGATE (PLG) REAR SWITCH REMOVAL/INSTALLATION.)
3	INSPECT POWER LIFTGATE (PLG) CONTROL MODULE CONNECTOR CONDITION • Disconnect the power liftgate (PLG) control module connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
3		No	Repair or replace the connector, then go to Step 5.
4	INSPECT POWER LIFTGATE (PLG) REAR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Verify that the power liftgate (PLG) rear switch and power liftgate (PLG) control module connectors are disconnected. • Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Switch the ignition ON (engine off or on). • Measure the voltage at the power liftgate (PLG) rear switch terminal C (wiring harness-side). • Is the voltage 0 V?	Yes	Go to the next step.
4		No	Refer to the wiring diagram and verify whether or not there is a common connector between power liftgate (PLG) rear switch terminal C and power liftgate (PLG) control module terminal 1AF. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to the next step.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Always reconnect all disconnected connectors. • Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Clear the DTC for the power liftgate (PLG) control module using the M-MDS. (See CLEARING DTC [POWER LIFTGATE (PLG) CONTROL MODULE].) • Retrieve the power liftgate (PLG) control module DTCs using the M-MDS. (See DTC INSPECTION [POWER LIFTGATE (PLG) CONTROL MODULE].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the power liftgate (PLG) control module. (See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION.) Go to the next step.
5		No	Go to the next step.
6	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [POWER LIFTGATE (PLG) CONTROL MODULE].)
6		No	DTC troubleshooting completed.
