Diagnostic Procedure

DTC B1DA8:24 (RETRACTABLE HARDTOP CONTROL MODULE) DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	VERIFY OTHER RETRACTABLE HARDTOP CONTROL MODULE DTCs Clear the DTC for the retractable hardtop control module using the M-MDS. (See CLEARING DTC [RETRACTABLE HARDTOP CONTROL MODULE] .) Retrieve the retractable hardtop control module DTCs using the M-MDS. (See DTC INSPECTION [RETRACTABLE HARDTOP CONTROL MODULE] .) Is the DTCs U3000:44/U3000:45/U3000:49 displayed?	Yes	Replace the retractable hardtop control module, then go to Step 5. (See RETRACTABLE HARDTOP CONTROL MODULE REMOVAL/INSTALLATION .)
1		No	Go to the next step.
2	INSPECT TOP LOCK SWITCH CIRCUIT FOR OPEN CIRCUIT Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the retractable hardtop control module and top lock switch connectors. Inspect the wiring harness for continuity between the following terminals (wiring harness-side): Retractable hardtop control module terminal 1G and top lock switch terminal A Is there continuity?	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 hardtop control module terminal 1G and top lock switch terminal A 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 an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 5.
3	INSPECT TOP LOCK SWITCH CIRCUIT FOR OPEN CIRCUIT Verify that the retractable hardtop control module and top lock switch connectors are disconnected. Inspect the wiring harness for continuity between the top lock switch terminal B (wiring harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
3		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Top lock switch terminal B and body ground 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 an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 5.
4	INSPECT TOP LOCK SWITCH Inspect the top lock switch. (See TOP LOCK STRIKER INSPECTION .) Is the top lock switch normal?	Yes	Go to the next step.
4		No	Replace the top lock switch, then go to the next step. (See TOP LOCK STRIKER REMOVAL/INSTALLATION .)
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 retractable hardtop control module using the M-MDS. (See CLEARING DTC [RETRACTABLE HARDTOP CONTROL MODULE] .) Retrieve the retractable hardtop control module DTCs using the M-MDS. (See DTC INSPECTION [RETRACTABLE HARDTOP CONTROL MODULE] .) Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the retractable hardtop control module. (See RETRACTABLE HARDTOP 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 [RETRACTABLE HARDTOP CONTROL MODULE] .)
6		No	DTC troubleshooting completed.
