FUNCTION
The diagnostic result demonstrates that "the scan tool cannot receive the sent data from the ECM <M/T> or PCM <A/T>" when the scan tool MB991958
checks the periodically sent data from each ECU and cannot receive the ECM <M/T> or PCM <A/T> data only.
TROUBLE JUDGEMENT CONDITIONS
Scan tool MB991958 judges the trouble when the periodically sent data from the ECM <M/T> or PCM <A/T> cannot be received and sent.
TROUBLESHOOTING HINTS
-
The wiring harness may be defective (open circuit between ABS-ECU <vehicles without traction control system> or ABS/TCL-ECU <vehicles
with traction control system> and ECM <M/T> or PCM <A/T>)
-
The connector may be defective (poor connection of ECM <M/T> or PCM <A/T> connector and ABS-ECU <vehicles without traction control
system> or ABS/TCL-ECU <vehicles with traction control system> connector)
-
power supply circuit malfunction of the ECM <M/T> or PCM <A/T>
-
The ABS-ECU <vehicles without traction control system> or ABS/TCL-ECU <vehicles with traction control system> may be defective (internal
open circuit)
-
The ECM <M/T> or PCM <A/T> may be defective
