Refer to “A/C System Performance Inspection”.
A/C System Inspection at ECM
S7RS0B7224028
Voltage Check
ECM and its circuits can be checked by measuring voltage with special tool connected.
CAUTION
!
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the
grommet. Therefore, do not measure circuit voltage and resistance by inserting the tester’s probe
into the sealed terminal at the harness side. Or, ECM and its circuits may be damaged by water.
• ECM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ECM
with couplers disconnected from ECM.
1) Remove ECM (1) from its bracket by referring to “Electric Throttle Body System Calibration in Section 1C”.
2) Connect special tool (2) between ECM and ECM connectors securely.
3) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that the battery voltage is 11 V or
more when ignition switch is ON position.
