System DescriptionINFOID:0000000005929014
M/T Models
Power is supplied at all times
• to starter motor terminal B, and
• through 40A fusible link (letter h, located in the fuse and fusible link box)
• to ignition switch terminal B.
With the ignition switch in the START position, power is supplied
• from ignition switch terminal ST
• to IPDM E/R terminal 21.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse (No. 49, located in the IPDM E/R)
• to the clutch interlock switch terminal 1.
With the clutch pedal depressed, power is supplied
• through the clutch interlock switch terminal 2
• to IPDM E/R terminal 35.
Ground is supplied at all times
• to IPDM E/R terminals 39 and 59
• through body grounds E15 and E24.
If the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN communication lines,
the IPDM E/R grounds the starter relay and power is supplied
• through terminal 19 of the IPDM E/R
• to terminal S of the starter motor.
The starter motor magnetic switch energizes closing the circuit between the battery and the starter motor. The
starter motor is case ground through the cylinder block. With power and ground supplied, the starter motor
operates.

2.CHECK VOLTAGE DROP ON MAGNETIC SWITCH CIRCUIT
1. Connect starter motor connector F28.
2. Check voltage between starter motor connector F28 terminal S and battery positive terminal using a digital circuit tester.
OK or NG
OK >> Magnetic switch circuit is OK. Further inspection is nec-
essary. Refer to "WORK FLOW".
NG >> Check harness, components and connections between the battery and the magnetic switch for poor continuity.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005931248
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s
peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N 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 communicate data but selectively reads required data only.
