CUMULATIVE BATTERY DISCHARGE CURRENT CLEAR

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.

DTC/CIRCUIT DIAGNOSIS

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.

• The status just before activation of fail-safe control is maintained until the ignition switch is 

turned OFF while the front wiper is operating at LO or HI speed.

• The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-safe con-

trol is activated while the front wiper is set in the INT mode and the front wiper motor is op-
erating.
