USE OF SDS DIAGNOSTIC PROCEDURES
* Don’t disconnect couplers from ECM, the battery cable from
the battery, ECM ground wire harness from the engine or main
fuse before confirming the malfunction code (self-diagnostic
trouble code) stored in memory. Such disconnection will erase
the memorized information in ECM memory.
* Malfunction code stored in ECM memory can be checked by
the SDS.
* Be sure to read “PRECAUTIONS IN SERVICING” (
4-3)
before inspection and observe what is written there.
• Remove the front seat. (8-7)
• Set up the SDS tool. (Refer to the SDS operation manual for
further details.)
• Read the DTC (Diagnostic Trouble Code) and show data
when trouble (displaying data at the time of DTC) according to
instructions displayed on SDS.
• Not only is SDS used for detecting Diagnostic Trouble Codes
but also for reproducing and checking on screen the failure
condition as described by customers using the trigger.
• How to use trigger. (Refer to the SDS operation manual for
further details.)
