PTG System (Power Tail Gate system)

2 Concept of the PTG (Power Tail Gate) Using PTG motor operation, tail gate is open and close by push load moving to up and down Push Load PTG Motor Channel PTGM PTG General

3 Auto-controlled for tail gate latch to lock or release by motor power Automatic tail gate opening and closing using the electrical motor System Introduction Power Tail Gate General

4 System Input & Output Battery Power for Memory & Relay System Power from J/Box Ignition Power from ignition Key Vehicle speed signal from Cluster PTG Off switch Anti pinch strip switch PTG Main switch Local switch (Handle & Trip) Transmitter signal Primary switch signal Secondary switch signal Detent switch signal Power Latch DLC K Line BCMBCM Inhibitor P position Engine starting signal Warning Buzzer Unlatch Motor M Cinch Motor M Power Latch PTG Clutch PTG Motor M PTGCMPTGCM Optical sensor

5 Transmitter PTG switch (on the tail gate) PTG main switch (Driveling room lower crush pad) PTG OFF switch (located in glove box) PTG Assy (PTG Motor & Control module) PTG trim switch (on the tail gate trim) Power latch (Unlatch motor & Cinch motor) Anti pinch switch (LH/RH side) PTG buzzer PTG System components

6 PTG Assembly System assy location : LH side D LH D pillar PTG System components PTG Control Module Motor Push road

7 Power Latch Cinch motor Unlatch motor Lock release lever PTG components

8 Anti Pinch Strip Strip Steel Air gap PTG components

9 Possible to open or close the TG by electric power (Mainly for open) Located inside tail gate outside handle rubber (Self-return type) PTG components PTG Switch : outside handle

10 PTG main switch : lower crush pad PTG on-off switch is mainly for the driver Main PTG Switch Located on the lower crash pad (driver side) (Self-return type) PTG components

11 PTG Tail gate trim switch Located on the lower of the tail gate (uncontrolled close condition) Possible to open or close the TG by electric power (Mainly for close) PTG components

12 Glove box PTG OFF switch Local switches (outside handle S/W, trim S/W) wont be functioned Located passengers globe box (uncontrolled close the globe box) PTG components

13 Description Optical sensor used in PTG system has several important functions. It has - Obstacle detection - Door opening and closing direction feedback - Travel calculation When this sensor has failure all operation are prohibited. (Passable to manual operating ) Optical Sensor 3 POWER(5V) OPTICAL SENSOR PTGM 23 SENSOR1 18 SENSOR GND

14 Description When pinch sensor is depressed which means any obstacle is detected, by following the PTG movement direction, it immediately goes to reverse direction. Optical Sensor Waveform

15 PTG Buzzer Just before PTG opening, stuck in the obstacle, under abnormal operation condition, this PTG module will be operating the buzzer Just before PTG opening, stuck in the obstacle, under abnormal operation condition, this PTG module will be operating the buzzer Located inside tail gate trim (RH) PTG Component

18 Operating conditionPTG Switch operationStatus of operation Outside handle switch Fully open Close (hazard lamp & buzzer OFF) - Shift lever P - Vehicle speed 0 - All door : unlock - PTG OFF S/W OFF PTG Main Control Specification 1 Trim switch Fully open Close (hazard lamp & buzzer 3 times) Remote control switch Fully open Close (hazard lamp & buzzer 3 times) Main switch Fully open Close (hazard lamp & buzzer 3 times) Again operating the switch On/Off Master switch (Remote & Crash pad S/W) Reverse immediately (Flicker hazard lamp 2 times) Local switch (Outside handle & Trim switch) Reverse immediately (hazard lamp & buzzer OFF)

19 Operating ConditionPTG Switch operation Status of operation PTG Main Control Specification 2 IG ON & Not P range - Outside handle switch - Remote control switch - Crash pad switch - Trim switch Not possible to Open/Close (Available to close just 1 time) Obstacle is detected by internal optical sensor Obstacle is detected by Anti pinch strip (APS) Obstacle detection while PTG operation - Opening : Motor off - Closing : Motor reverse - Opening : Not affects - Closing : Motor reverse All door lock condition - Remote control switch - Main switch - Trim switch - Outside handle switch Possible to Open/Close Possible to open/close (Available to close just 1 time)

20 Operating conditionPTG switch operationStatus of operation Driving - Remote control - Crash pad switch - Outside handle switch - Trim switch Impossible to Open ( Available to close 1 time for safety expect remote control) PTG Main Control Specification 3 Push the PTG OFF Switch button ON - Main switch switch - Remote control switch - Outside handle switch - Trim switch Possible to Open/Close Impossible to Open/Close (Release the latch)

21 Diagnosis Be used to detect the PTG system with Scan tool (K-LINE ) PTG Diagnosis

22 Current Data Be available to check the BCM (input/output) with scan tool PTG Current Data

23 PTG Current Data

24 PTG Current Data

25 Actuation test Be available to check the output Actuation test by scan tool. PTG Troubleshooting & Diagnosis

26 Cut off the PTG ECU memory power (Battery was removed) Completion of Reset Close the tail gate manually if the gate was opened Impossible to close automatically Completely close the tail gate with motor power Confirm the normal operation Open the tail gate with motor power Using remote control, crash pad switch, outside handle Completion of Initialization Anti pinch strip sensor and reverse operation will be available while the initialization Method for initialization of PTG system
