CUMULATIVE BATTERY DISCHARGE CURRENT CLEAR
Description
INFOID:0000000010499185
CUMULATIVE BATTERY DISCHARGE CURRENT CLEAR is an operation to clear the cumulative value of
battery discharge current which is memorized in IPDM E/R. This operation is necessary after replaced the bat-
tery.
Work Procedure
INFOID:0000000010499186
1.
CLEAR CUMULATIVE BATTERY DISCHARGE CURRENT VALUE
1.
Turn ignition switch ON.
2.
Select “CML B/DCHRG CRNT CLEAR” in “Work Support” mode of “IPDM E/R” using CONSULT.
3.
Touch “CLEAR” to clear the cumulative value of battery discharge current.

U1000 CAN COMM CIRCUIT
DTC Description
INFOID:0000000010499193
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
DTC DETECTION LOGIC
POSSIBLE CAUSE
CAN communication system
FAIL-SAFE
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.
If No CAN Communication Is Available With ECM
If No CAN Communication Is Available With BCM
DTC CONFIRMATION PROCEDURE
1.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Turn the ignition switch OFF.
2.
Turn the ignition switch ON and wait for 2 seconds or more.
3.
Check “Self Diagnostic Result” of IPDM E/R.
