Components DescriptionAKS006YD
CAN CommunicationAKS00815
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 speed and excellent error detection ability. Many elec-
tric control units are equipped onto a vehicle, 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.
CAN COMMUNICATION UNIT
Refer to LAN-6, "CAN Communication Unit" .
Switch OperationAKS006YF
The system is operated by a master ON/OFF switch and four control switches, all mounted on the steering
wheel.

7. CHECK ICC BRAKE HOLD RELAY CIRCUIT
1. Disconnect connectors of ICC unit and stop lamp switch.
2. Check continuity between ICC unit harness connector M89 ter-
minal 38 (P/G) and ICC brake hold relay harness connector E14
terminal 7 (P).
3. Check continuity between ICC unit harness connector M89 ter-
minal 38 (P/G) and stop lamp switch harness connector E210
terminal 2 (P).
OK or NG
OK >> Replace ICC unit. Erase DTC and perform ICC system
running test. Then perform self-diagnosis of ICC system again.
NG >>

Repair harness between ICC unit and ICC brake hold relay.

After repair, erase DTC and perform ICC system running test. Then, perform self-diagnosis of
ICC system again.

nosis of ICC system again.
OK or NG
OK >>
Poor connector connection.

Check connector. (Check connector housing for disconnected, loose, bent, and collapsed ter-
minals. If any malfunction is detected, repair applicable part.) After repair, erase DTC, and per-
form ICC system running test. Then perform self-diagnosis of ICC system again.
NG >> GO TO 2.
2. CHECK ICC STEERING SWITCH

Check ICC steering switch, refer to ACS-65, "ICC Steering Switch" .
OK or NG
OK >> GO TO 3.
NG >> Replace ICC steering switch (steering wheel assembly). Erase DTC and perform ICC system run-
ning test. Then perform self-diagnosis of ICC system again. Continuity should exist.
Continuity should exist.
