TERMINALS OF ECM
CHECK ECM
HINT:
The standard normal voltage between each pair of ECM terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the Specified Condition column. The illustration above can be used as a reference to identify the ECM terminal locations.
Terminal No. (Symbol) | Terminal Description | Condition | Specified Condition |
A106-1 (BATT) - A106-10 (E1) | Auxiliary battery (for measuring auxiliary battery voltage and for ECM memory) | Always | 11 to 14 V |
A106-10 (E1) - Body ground | Ground | Always | Below 1 Ω |
D104-62 (LIN) - Body ground | LIN communication line | Ignition switch off (while LIN communication stopped) | 10 kΩ or higher |
PROBLEM SYMPTOMS TABLE HINT:

Other information:
DESCRIPTION The air by-pass valve assembly is installed in the air outlet duct. It opens and closes in response to drive commands from the ECM. During normal boosting, the air by-pass valve assembly is closed, and when the throttle valve is closed while the boost pressure is applied, the air by-pass valve assembly opens and the excess pressure between the turbocharger and throttle valve is released to prevent the surge phenomenon*...
