Inspection 15 CAN Communication Circuit, ESP/TCS/ABS Control Unit and
Steering Angle Sensor
EFS005WK
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ESP/TCS/ABS control unit connector, and check the terminal for
deformation, disconnection, looseness, and so on. If there is a malfunction, repair or replace the terminal.
2. Reconnect connector to perform self-diagnosis.
Is
“CAN COMM CIRCUIT” or “ST ANG SEN COM CIR” displayed in the self-diagnosis display items?
YES >> Print out the self-diagnostic results, and refer to BRC-56, "CAN COMMUNICATION" .
NO >> Connector terminal connection is loose, damaged, open, or shorted.
Component CheckEFS005WL
ESP OFF SWITCH

Disconnect the ESP OFF switch connector. Check for continuity
between the terminal No. 1 and No. 2.
ESP RELAY BOX
Disconnect the relay box connectors. Check for continuity, resis-
tance value, and insulation between any pair of terminals in the relay
box. 1 - 2 : Pressing the switch will make a continu-
ity, and releasing it will stop the continuity.

HEATER & COOLING UNIT ASSEMBLY

9. Remove steering member.
10. Remove heater & cooling unit.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace the O-ring of the low-pressure flexible hose and the high-pressure pipe with a new one,
and then apply compressor oil to it when installing it.

When recharging refrigerant, check for leaks.
NOTE:
When filling radiator with coolant, refer to CO-9, "
Changing Engine Coolant" for QR engine or CO-32, "Chang-
ing Engine Coolant" for YD engine.
