ECM

ECM : Description

INFOID:0000000007579663

Performing the following procedure can automatically activate recommunication of ECM and BCM, but only
when the ECM is replaced with a new one*.
*: New one means a virgin ECM that has never been energized on-board.
(In this step, initialization procedure by CONSULT is not necessary)
NOTE:
• If multiple keys are attached to the key holder, separate them before beginning work.
• Distinguish keys with unregistered key IDs from those with registered IDs.

ECM : Work Procedure

INFOID:0000000007579664

1.

PERFORM ECM RECOMMUNICATING FUNCTION

1.

Install ECM.

2.

Contact backside of registered Intelligent key* to push-button ignition switch, then turn power supply posi-
tion to ON.
*: To perform this step, use the key that is used before performing ECM replacement.

3.

Maintain power supply position in the ON position for at least 5 seconds.

4.

Turn power supply position to OFF.

5.

Check that the engine starts.

BCM

BCM : Description

INFOID:0000000007579665

BEFORE REPLACEMENT

When replacing BCM, save or print current vehicle specification with CONSULT configuration before replace-
ment.
NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing BCM.

AFTER REPLACEMENT

CAUTION:

When replacing BCM, always perform “WRITE CONFIGURATION” with CONSULT. Or not doing so,
BCM control function does not operate normally.
• Complete the procedure of “WRITE CONFIGURATION” in order.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• If you set incorrect “WRITE CONFIGURATION”, incidents might occur.
NOTE:
When replacing BCM, perform the system initialization (NATS).

BCM : Work Procedure

STOP LAMP

BCM makes a comparison between the 
upper voltage and lower voltage of stop 
lamp switch. It judges from their values to 
detect the malfunctioning circuit.

• Harness or connectors

(Stop lamp switch circuit is open or 
shorted.)

• Stop lamp switch
