Terminals Of Control Module/Pinouts-Air Conditioning Amplifier (Part 3):




1. AIR CONDITIONING AMPLIFIER




a. waveform 1:
1. Measure the voltage between terminal SPD of the A/C amplifier assembly connector and body ground when turning the rear wheel slowly.

OK:
Waveform operate as shown in the illustration.

HINT: As vehicle speed increases, the cycle of the signal waveform narrows.




b. waveform 2:
1. Measure the waveform between terminal LCK1 (E6-23) of the ECM and body ground.

OK:
Waveform operate as shown in the illustration.

HINT: As vehicle speed increases, the cycle of the signal waveform narrows.
