ECM Harness Connector Terminal LayoutABS006KV
ECM Terminals and Reference ValueABS006KW
PREPARATION
1. ECM is located behind the passenger side instrument lower
panel. For this inspection, remove passenger side instrument
lower panel.
2. Remove ECM harness connector.
3. When disconnecting ECM harness connector, loosen it with levers as far as they will go as shown in the figure.
4. Connect a break-out box (SST) and Y-cable adapter (SST) between the ECM and ECM harness connector.

Use extreme care not to touch 2 pins at one time.

Data is for comparison and may not be exact.
ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
