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 |
