Title: AIR CONDITIONING: AIR CONDITIONING SYSTEM (for Manual Air Conditioning System): SYSTEM DESCRIPTION; 2015 MY Tundra [08/2014 - ]

SYSTEM DESCRIPTION

1. GENERAL

(a) The air conditioning system has the following controls:

CONTROL

OUTLINE

Manual Control

The air conditioning amplifier controls the damper positions (air inlet control damper, air mix control damper and mode control damper)

MAX A/C

Control

When the temperature control switch is in the MAX A/C position, the air conditioning amplifier turns the compressor on and activates the

servo motor (air inlet) to set the air inlet control damper to the RECIRC position, improving the cooling efficiency.

Compressor

Control

The air conditioning amplifier compares the pulley speed signals, which are transmitted by the lock sensor located on the air conditioning

compressor, with the engine speed signals, which are transmitted by the ECM (crankshaft position sensor). When the air conditioning

amplifier determines that the pulley is locked, it turns off the magnetic clutch.

Self-Diagnosis

A DTC (Diagnostic Trouble Code) is stored in the memory when the air conditioning amplifier detects a problem with the air conditioning

system.
