3	Power retractable hardtop does not to start open
DESCRIPTION	Power retractable hardtop does not start to open when the power retractable hardtop (open) switch is pressed
POSSIBLE CAUSE	Power retractable hardtop control module cannot detect the power retractable hardtop permission condition signal. Improper vehicle speed detected Improper transmission position detected (except for transmission neutral (MT)/N or P position (AT) detected) Power retractable hardtop control module cannot detect the proper power retractable hardtop switch signal. Power retractable hardtop (open) switch malfunction (stuck off) Power retractable hardtop (close) switch malfunction (stuck on) Open or short circuit in the wiring harness between the power retractable hardtop control module and the power retractable hardtop switch. Release of the top lock cannot be determined by the Power retractable hardtop control module. Top lock switch malfunction Open or short circuit in the wiring harness between the top lock switch and the power retractable hardtop control module Power retractable hardtop control module cannot detect proper deck panel and roof positions Deck panel open position switch signal improper Deck panel open position switch malfunction Deck panel open position switch improper installation Open or short circuit in the wiring harness Deck panel close position switch signal malfunction Deck panel close position switch malfunction Deck panel close position switch improper installation Open or short circuit in the wiring harness Power retractable hardtop open position switch signal malfunction Power retractable hardtop open position switch malfunction Power retractable hardtop open position switch improper installation Open or short circuit in the wiring harness Power retractable hardtop close position switch signal malfunction Power retractable hardtop close position switch malfunction Power retractable hardtop close position switch improper installation Open or short circuit in the wiring harness Power retractable hardtop link mechanics malfunction Excessive restriction or hesitation Power retractable hardtop control module detects a system malfunction NOTE: If the following conditions are recognized, the power retractable hardtop control module invalidates the operation of the power retractable hardtop (open) switch. Top lock is locked with the power retractable hardtop fully closed Power retractable hardtop the fully open

Diagnostic Procedure

When performing the asterisked (*) troubleshooting inspection, slightly shake the wiring harness and connectors while performing the inspection to determine whether poor contact points are the cause of any intermittent malfunction. If there is a problem, verify that the connectors, terminals and the wiring harness are connected correctly and undamaged.


STEP	INSPECTION		ACTION
1	INSPECT TO SEE WHETHER MALFUNCTION IS IN OPERATION PERMISSION CONDITION SIGNAL OR ELSEWHERE Connect the M-MDS to the DLC-2. Monitor the following PIDs. (See PCM INSPECTION [LF].) (See PID/DATA MONITOR INSPECTION [SJ6A-EL].) (See POWER RETRACTABLE HARDTOP CONTROL MODULE INSPECTION.) PCM VSS PNP/CPP (MT) CPP (MT) TCM (AT) TR Power Retractable Hardtop Control Module VSS Are these monitor values normal?	Yes	Go to the next step.
1		No	Inspect and repair the suspected signal related wiring harness and component.
2*	INSPECT TO SEE WHETHER MALFUNCTION IS IN POWER RETRACTABLE HARDTOP (CLOSE) SWITCH SIGNAL OR ELSEWHERE Monitor the power retractable hardtop control module PID SW_CL (power retractable hardtop (close) switch) using the M-MDS without the power retractable hardtop (close) switch pressed. (See POWER RETRACTABLE HARDTOP CONTROL MODULE INSPECTION.) Is the monitor value OFF?	Yes	Go to step 4.
2*		No	Go to the next step.
3	INSPECT POWER RETRACTABLE HARDTOP (CLOSE) SWITCH Turn the ignition switch to the LOCK position. Remove the power retractable hardtop switch. Measure the resistance between power retractable hardtop switch component side connector terminals A and F without the power retractable hardtop (close) switch pressed. Is the resistance 2.18—2.22 kΩ?	Yes	Replace the power retractable hardtop switch. (See POWER RETRACTABLE HARDTOP SWITCH REMOVAL/INSTALLATION.)
3		No	Inspect and repair the wiring harness between power retractable hardtop control module terminal 1H and power retractable hardtop switch terminal F at wiring harness side connectors.
4	VERIFY THAT POWER RETRACTABLE HARDTOP INDICATOR LIGHT ILLUMINATION Turn the ignition switch to the ON position. Verify the power retractable hardtop indicator light status. Does the power retractable hardtop indicator light flash or illuminate?	Yes	If the indicator light is flashing: Go to the next step. If the indicator light is illuminated: Go to step 6.
4		No	Go to step 9.
5	VERIFY THAT PRESENT MALFUNCTION DTC IS STORED Connect the M-MDS to DLC-2. Retrieve the DTC for the power retractable hardtop control module. (See DTC INSPECTION [POWER RETRACTABLE HARDTOP].) Is there any present malfunction DTC?	Yes	Go to the appropriate DTC inspection. (See DTC TABLE [POWER RETRACTABLE HARDTOP].)
5		No	Go to symptom troubleshooting “No.2 POWER RETRACTABLE HARDTOP INDICATOR LIGHT IS FLASHING” procedure.
6*	INSPECT TO SEE WHETHER MALFUNCTION IS IN TOP LOCK SWITCH OR ELSEWHERE Connect the M-MDS to DLC-2. Monitor the power retractable hardtop control module PID SW_STRIKER using the M-MDS while the top lock switch is released. (See DTC INSPECTION [POWER RETRACTABLE HARDTOP].) Is the monitor value OFF?	Yes	Go to step 8.
6*		No	Go to the next step.
7	INSPECT TOP LOCK SWITCH Inspect the top lock switch. (See TOP LOCK SWITCH INSPECTION [ADVANCED KEYLESS SYSTEM].) Is the top lock switch normal?	Yes	Inspect and repair for an open or short circuit between the top lock switch and power retractable hardtop control module.
7		No	Replace the top lock. (See FRONT ROOF PANEL DISASSEMBLY/ASSEMBLY.)
8*	INSPECT POWER RETRACTABLE HARDTOP LIMIT SWITCH AND DECK PANEL LIMIT SWITCH Monitor the power retractable hardtop control module PID RHT_OP, RHT_CL, DECK_OP and DECK_CL using the M-MDS. Do the monitoring values indicate the roof and deck panel positions properly?	Yes	Verify that the malfunction symptom appears without the roof and deck panel in the fully open position. If the same symptom appears, replace the power retractable hardtop control module. (See POWER RETRACTABLE HARDTOP REMOVAL/INSTALLATION.)
8*		No	Inspect and repair suspected position sensor. (See POWER RETRACTABLE HARDTOP LIMIT SWITCH INSPECTION.) (See DECK PANEL LIMIT SWITCH INSPECTION.)
9*	INSPECT TO SEE WHETHER MALFUNCTION IS IN POWER RETRACTABLE HARDTOP (OPEN) SWITCH SIGNAL OR ELSEWHERE Monitor the power retractable hardtop control module PID SW_OP using the M-MDS while the power retractable hardtop (open) switch is pressed. Is the monitor value ON?	Yes	Go to step 10.
9*		No	Go to the next step.
10	INSPECT POWER RETRACTABLE HARDTOP (OPEN) SWITCH Remove the power retractable hardtop switch. Measure the resistance between power retractable hardtop switch connector (component side) terminal A and F while the power retractable hardtop (open) switch is pressed. Is the resistance 0.99—1.01 kΩ?	Yes	Inspect and repair the wiring harness between power retractable hardtop control module terminal 1H and power retractable hardtop switch terminal F at the wiring harness side connectors.
10		No	Replace the power retractable hardtop switch.
11	INSPECT POWER RETRACTABLE HARDTOP LINK MECHANICS Inspect the power retractable hardtop link mechanics. Is there any restriction or hesitation with power retractable hardtop operation?	Yes	Repair or replace the malfunctioning part.
11		No	Replace the power retractable hardtop control module. (See POWER RETRACTABLE HARDTOP CONTROL MODULE REMOVAL/INSTALLATION.)
