Manual Description
POWER SUPPLY AND GROUND CIRCUIT 19, iPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) 20, wiring Diagram - IPDM E/R -27, eXCEPT FOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR BAG".
EXCEPT FOR MEXICO : Precaution Battery, eXCEPT FOR MEXICO : Precaution for Procedure without Cowl Top Cover33, fOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR BAG" "SEAT BELT, fOR MEXICO : Precaution Battery Service34.
FOR MEXICO : Precaution Procedure without, iPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM) 35, dIAGNOSIS AND REPAIR WORK FLOW 37, pOWER SUPPLY AND GROUND CIRCUIT 68.
COMMON ITEM : CONSULT-III Function (BCM COMMON ITEM) 43, pUSH-BUTTON IGNITION SWITCH POSITION INDICATOR 71, wiring Diagram - PDS (POWER DISTRIBUTION, wiring Diagram - BCM - 105.
EXCEPT FOR MEXICO : Precautions Necessary, for Steering Wheel Rotation After Battery Disconnection 117, fOR MEXICO : Precautions Necessary for Steering Wheel Rotation After Battery Disconnection 118, fOR MEXICO : Precaution Battery Service 119.
PUSH-BUTTON IGNITION SWITCH POSITION INDICATOR DOES NOT ILLUMINATE 121, steering lock relay and steering lock unit, as shown in the system diagram, are for models with steering lock, iPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication, iPDM E/R integrated relays cannot be removed.
*: For models with steering lock unit only, iPDM E/R outputs pulse duty signal (PWM signal) to the cooling fan control module according status, the cooling fan speed request signal received from ECM via CAN communication, iPDM E/R outputs power generation command signal (PWM signal) to the alternator according status.
The power generation command value signal received from ECM via CAN communication, iPDM E/R reads the status of the oil pressure switch and transmits the oil pressure switch signal BCM via, iPDM E/R reads the status of the hood switch and transmits the hood switch signal to BCM via CAN communication, iPDM E/R receives the rear window defogger control signal from BCM via CAN communication and transmits it to ECM and AV control unit via CAN communication.
Diagram" (With navigation), DEF-91, "WITHOUT NAVIGATION : System Diagram" (Without navigation), iPDM E/R incorporates a power consumption control function that reduces the power consumption according vehicle status, iPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN communication, - CAN communication is normally performed with other control units.
- Individual unit control by IPDM E/R normally performed, - Low power consumption control active, iPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF none, - Hood switch status is kept 50 ms less.
- Output requests are being received from control units via CAN communication, iPDM E/R stops CAN communication and enters the low power consumption mode when it receives sleep, wake up signal (sleep) from BCM and the sleep-ready conditions fulfilled, iPDM E/R changes from the low power consumption mode to the normal mode when it receives sleep.
Wake-up signal (wake up) from BCM or any of the following conditions is fulfilled, sleep-ready signal (not-ready) to BCM via CAN communication to report CAN communication start, - The hood switch status changes, - An output request is received from a control unit via CAN communication.
In auto active test mode, the IPDM E/R sends a drive signal to the following systems check their operation, cooling fan (cooling fan control module), close the hood and lift the wiper arms from the windshield, when auto active test is performed with hood opened, sprinkle water windshield beforehand.
Then turn ignition switch OFF, when auto active test mode has to be cancelled halfway through test, turn ignition switch OFF, if auto active test mode cannot be actuated, check door switch system.
