B24D4 A/C CONTROL COMMUNICATION

DTC Logic

INFOID:0000000010499359

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness and connector (A/C control circuit is open or shorted)
• A/C control
• A/C auto amp.

FAIL-SAFE

If a communication error exists between the A/C auto amp. and A/C control for 30 seconds or longer, air con-
ditioning is controlled under the following conditions: A/C auto amp. is controlled in the setting state before the
communication error occurs for following setting.
• Set temperature
• Air outlet
• Blower fan speed
• Air inlet
• A/C switch

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1.

Turn ignition switch ON.

2.
