FREEZE FRAME DATA
1. FREEZE FRAME DATA
(a) When a DTC is stored, the 4 wheel drive control ECU stores the current vehicle state as Freeze Frame Data.
HINT:
Freeze Frame Data at the time a DTC is stored:
When the 4 wheel drive control ECU stores data at the time a DTC is stored, no updates will be performed until the data is cleared.
2. CHECK FREEZE FRAME DATA
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Enter the following menus: Powertrain / Four Wheel Drive / Trouble Codes.
(f) According to the display on the Techstream, select the trouble code data display with Freeze Frame Data.

Compressor Lock Sensor Circuit (B1422/22)
SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the air conditioning amplifier assembly
via CAN communication.
The air conditioning amplifier assembly reads the difference between compressor
speed and engine speed. When the difference becomes too large, the air conditioning
ampli ...
