ECM Harness Connector Terminal Layout ABS006KV

ECM Terminals and Reference Value ABS006KWPREPARATION1. ECM is located behind the passenger side instrument lower

panel. For this inspection, remove passenger side instrumentlower panel.

2. Remove ECM harness connector.

3. When disconnecting ECM harness connector, loosen it withlevers 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 TABLESpecification 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.

CONSULT-II Function (ENGINE) ABS006KXFUNCTION

*: The following emission-related diagnostic information is cleared when the ECM memory is erased.

● Diagnostic trouble codes

● 1st trip diagnostic trouble codes

● Freeze frame data

● 1st trip freeze frame data

● System readiness test (SRT) codes

● Test values

Diagnostic test mode Function

Work supportThis mode enables a technician to adjust some devices faster and more accurately by following the indications on the CONSULT-II unit.

Self-diagnostic resultsSelf-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame data can be read and erased quickly.*

Data monitor Input/Output data in the ECM can be read.

Data monitor (SPEC)Input/Output of the specification for Basic fuel schedule, AFM, A/F feedback control value and the other data monitor items can be read.

CAN diagnostic support monitor

The results of transmit/receive diagnosis of CAN communication can be read.

Active testDiagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also shifts some parameters in a specified range.

Function test This mode is used to inform customers when their vehicle condition requires periodic maintenance.

DTC & SRT confirmation The status of system monitoring tests and the self-diagnosis status/result can be confirmed.

ECM part number ECM part number can be read.
