| DTC Strategy |
- IPM monitors the internal error of ESCL and Lock/Unlock state by communicating with ESCL. (ESCL gets power from PDM for to communicate between IPM and ESCL.)
- ESCL Lock/Unlock state check by CAN signal from PDM
|
- IPM power ON
- ESCL internal error check: Check ESCL Failure on GDS among IPM Input/Output monitoring items. (When ON, It's ESCL internal error.)
- Check ESCL Battery/Ground line open: Check ESCL Open state check item among PDM's items on GDS.
- Check ESCL Battery/Ground line short to battery or ground: Check DTC among PDM's DTC list (ESCL BAT SCB, ESCL BAT SCG, ESCL Gnd SCB)
- Check ESCL Comm. Line short to battery or ground or open: Check ESCL Data Line state among IPM items on GDS.
- Check O_ESCL Enable Line's error among IPM's output lines: Check ESCL Enable=ON/OFF item among Input/Output monitoring items on GDS. (When push the button, the Data turns to ON momently.)
- Check L_ESCL_Unlock among PDM's input lines: Check ESCL Unlock item among PDM's Input/Output items on GDS.
- Check PDM's VbatLoad line: Check Vbat_Load among PDM's Input/Output items on GDS.
- Check PDM Power terminal's Relay short to battery: ACC, IGN1, IGN2, Starter SCG among PDM's Input/Output items on GDS
- When push SSB during PDM actuation test (ACC, IGN1, IGN2, Starter Rly).
- Check IPM/PDM/ESCL learning state (IPM: Learnt, PDM: Learnt, ESCL: Normal)

| Enable Conditions |
- Common: IPM power ON
- In case of ESCL error
- ESCL internal error
- ESCL Power/Ground Line short to Power/Ground or Open
- ESCL Communication Line short to Power/Ground or Open
- O_ESCL Enable Line from IPM Open
- ESCL_Unlock Line to IPM Open or Short
- In case of no ESCL error
- No power to PDM (VBatLoad)
- PDM Power Relay (ACC, IGN1, IGN2, Starter Rly) short to battery
- During PDM actuation test (ACC, IGN1, IGN2, Starter Rly)
- Before finishing IPM/PDM/ESCL learning (All same pin code)
