HANDS-FREE PHONE SYSTEM ON BOARD DIAGNOSIS
During on board diagnosis the diagnosis function of TEL adapter unit starts with the operation of steering
switch and performs the diagnosis when ignition switch is turned to ACC.
On board diagnosis item
The on board diagnosis has 3 modes: the self-diagnosis mode that performs the trouble diagnosis, the
speaker adaptation data deleting mode and the hands-free phone system initialization mode.
CAUTION:
• Perform the diagnosis with the vehicle stopped.
• Perform STEP2 if necessary.
Self-diagnosis results
Self-diagnosis mode reads out the self-diagnosis results and indicates DTC on the display.
NOTE:
• Error count is read out simultaneously when reading out the DTC name.
• The errors are read out continuously when some errors occur at the same time. The DTC displays are com-
bined and displayed. For example, DTC 01100 is displayed when DTC 01000 and DTC 00100 are indicated
at the same time.

U1000 CAN COMM CIRCUIT
Description
INFOID:0000000003544741
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-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independently). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.
