Outside Mirror Memory Operation By The Memory Switch

1. If position switch (POS1 or POS2) is pressed within 5 seconds after pressing the memory switch under ignition 2 on, it registers current mirror position. (Memory permit status lasts for 5 seconds after memory switch ON. After 5 seconds, memory permits status terminates. In other words, current position is registered if the position switch (POS1 or POS2) is turned on, during the memory permit status). However, RH side mirror position is not registered during the LH side mirror manual switch operation.
2. Memory permit status is released if any of the following conditions is met If 5 seconds is elapsed after the memory switch is turned on If the ignition 2 is turned off When saving is completed If Ignition switch of the CAN communication data sent by the IPM is not "Run" or "Start". If Inhibit switch of the CAN communication data sent by the FAM is not "P". If vehicle speed of the CAN communication data sent by the cluster is "3 Km/h" or more.
3. Memory is cleared if the battery is removed.

Outside Mirror Memory And Replay Operation By Keyless

FAM controls the low/high wiper relay according to rain sensor signal when the wiper auto switch is turned to ON under IG ON.

Note. The rain sensor is mounted on the interior side of the front windshield glass behind the rearview mirror. If driver turns the wiper switch to AUTO, this signal is inputted to FAM by LIN communication. FAM transmits 5 steps of signals (Slow <--> Fast) from the wiper auto switch to the rain sensor. At the slowest step among the INT switch, the rain sensor becomes the most insensitive status. At the fastest step among the INT switch, the rain sensor becomes the most sensitive status to measure the amount of rain. So, the sensitivity of the rain sensor depends on the steps of the INT switch. The rain sensor transmits the desired speed of a wiper by duty signal to FAM.

Scheme 72

They are IPM (Inter Panel Module), FAM (Front Area Module), PDM (Power Distribution Module), DDM (Drive Door Module), ADM (Assist Door Module), ECW (Electronic Control Wiper), CLU (Cluster), MFSW (Multi Function Switch), PSM (Power Seat Module), SCM (Steering Control Module), PTM (Power Trunk Lid Module), FBWS (Front Back Warning System), DATC (Dual Auto Temperature Control Module).

*1 CAN (Controller Area Network) : CAN is serial bus communication type which links not only communication system but also control units each other.

*2 LIN (Local Interconnect Network) : LIN is serial communication type which is used in electrical control system. (This is less expensive.)

Scheme 79

B1602 CAN ERROR

Refer to DTC B1602 : CAN ERROR .

This is DTC which is related with communication error between IPM and other units.

( Control Units : IPM (Inter Panel Module), FAM (Front Area Module), PDM (Power Distribution Module), DDM (Drive Door Module), ADM (Assist Door Module), ECW (Electronic Control Wiper), CLU (Cluster), MFSW (Multi Function Switch), PSM (Power Seat Module), SCM (Steering Control Module), PTM (Power Trunk Lid Module), FBWS (Front Back Warning System))

Case1: After short between ADM CAN Low Line and High Line, short to ground together.

Case2: After short between ADM CAN Low Line and High Line, short to power together.

This code is occurred when It is not possible to transmit data by CAN Line in those way of Software and Hardware. But, It is possible to receive data by CAN Line.

This code reports BUS OFF status when data transmit error count number is over 255. The purpose is to verify the status of CAN controller and CAN communication line when error is detected.

According to operation condition, some of module which are connected to CAN line may not detect B1603.

Also, B1602 coincides with B1603 at all times.

All 13 units which consists of the Body Electrical Control System are linked by CAN *1 line.

*1 CAN (Controller Area Network) : CAN is serial bus communication type which links not only communication system but also control units each other.

*2 LIN (Local Interconnect Network) : LIN is serial communication type which is used in electrical control system. (This is less expensive.)

Scheme 80

This code reports the malfunction of NEC MCU inside PDM. This is the case which there is the NEC MCU communication error.

Refer to DTC B1987 : SUB MICOM FAILED .

This code is outputted when power circuit is shorted to battery.

(During no power supply from PDM to ESCL)

Refer to DTC B1987 : SUB MICOM FAILED .

This code is outputted when ground circuit is shorted to battery.

(During no power supply from PDM to ESCL)

Refer to DTC B1987 : SUB MICOM FAILED .

This code is outputted when power circuit is shorted to ground.

(During no power supply from PDM to ESCL)

Refer to DTC B1987 : SUB MICOM FAILED .

This code is outputted when the immobilizer data circuit is shorted to ground.

(In this case, it is not possible to get authorization although the fob is in the holder.)
