Diagnostic Procedure

Step	Inspection		Action
1	VERIFY OTHER RETRACTABLE FASTBACK CONTROL MODULE DTCs Clear the DTC for the retractable fastback control module using the M-MDS. (See CLEARING DTC [RETRACTABLE FASTBACK CONTROL MODULE] ). Retrieve the retractable fastback control module DTCs using the M-MDS. (See DTC INSPECTION [RETRACTABLE FASTBACK CONTROL MODULE] ). Is the DTCs U3000:44/U3000:45/U3000:49 displayed?	Yes	Replace the retractable fastback control module, then go to Step 4. (See RETRACTABLE FASTBACK CONTROL MODULE REMOVAL/INSTALLATION ).
1		No	Go to the next step.
2	FRONT ROOF LINK MOTOR (RH) CIRCUIT FOR SHORT TO POWER SUPPLY Switch the ignition off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION ). Disconnect the retractable fastback control module and front roof link motor (RH) connectors. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION ). Switch the ignition ON (engine off or on). Measure the voltage at the following terminals (wiring harness-side): Front roof link motor (RH) terminal A Front roof link motor (RH) terminal E Is the voltage 0 V?	Yes	Go to the next step.
2		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Retractable fastback control module terminal 3F and front roof link motor (RH) terminal A Retractable fastback control module terminal 3J and front roof link motor (RH) terminal E 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 Step 4.
3	FRONT ROOF LINK MOTOR (RH) Inspect the front roof link motor (RH). (See ROOF LINK MOTOR INSPECTION ). Is the front roof link motor (RH) normal?	Yes	Go to the next step.
3		No	Replace the front roof link motor (RH), then go to the next step. (See ROOF LINK MOTOR REMOVAL/INSTALLATION ).
4	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION ). Clear the DTC for the retractable fastback control module using the M-MDS. (See CLEARING DTC [RETRACTABLE FASTBACK CONTROL MODULE] ). Retrieve the retractable fastback control module DTCs using the M-MDS. (See DTC INSPECTION [RETRACTABLE FASTBACK CONTROL MODULE] ). Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the retractable fastback control module. (See RETRACTABLE FASTBACK CONTROL MODULE REMOVAL/INSTALLATION ). Go to the next step.
4		No	Go to the next step.
5	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 [RETRACTABLE FASTBACK CONTROL MODULE] ).
5		No	DTC troubleshooting completed.
