BEFORE REPLACEMENT
When replacing A/C auto amp., save or print current v ehicle specification with CONSULT configuration before
replacement.
NOTE:
If “Before Replace ECU” cannot be used, use the “After Replace ECU” or “Manual Configuration” after replac-
ing A/C auto amp.
AFTER REPLACEMENT
CAUTION:
• When replacing A/C auto amp., you must perform “After Replace ECU” with CONSULT.
- Complete the procedure of “After Replace ECU” in order.
- If you set incorrect “After Replace ECU”, incidents might occur.
- Configuration is different for each vehicle mode l. Confirm configuration of each vehicle model.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009463121
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped onto vehicl es, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with two 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. Refer to
LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
.

DTC CONFIRMATION PROCEDURE
1.PERFORM SELF-DIAGNOSIS
With CONSULT
1. Turn ignition switch ON and wait for 2 seconds or more.
2. Using CONSULT, perform “SELF- DIAGNOSIS RESULTS” of HVAC.
3. Check if any DTC No. is displayed in the self-diagnosis results.
Is DTC detected?
YES >> Refer to HAC-55, "Diagnosis Procedure".
NO >> Refer to GI-43, "Intermittent Incident"
