[54C] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Hong Kong spec.> - - SYMPTOM PROCEDURES - ELECTRIC RETRACTABLE REMOTE CONTROLLED DOOR MIRROR - INSPECTION PROCEDURE I-4: Vehicle speed-dependent unfolding function does not work normally.PRINT PAGE / INDEX / PRIOR / NEXT
INSPECTION PROCEDURE I-4: Vehicle speed-dependent unfolding function does not work normally.
 CAUTION
 Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates this function in accordance with the input signals below.
  • Ignition switch (IG1)
  • Vehicle speed signal (engine-A/T-ECU)
If this function does not work normally, these input signal circuit(s) or the ETACS-ECU may be defective. In addition, it is possible that the function except the vehicle speed-dependent unfolding function has been set by using the adjustment function.
POSSIBLE CAUSES
  • Malfunction of the vehicle speed signal (engine-A/T-ECU)
  • Malfunction of ETACS-ECU
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check the adjustment function.
Check that "WING MIRROR" is set to "SPEED SEN FUN" by using the adjustment function.
Q: Is the check result normal?
YES:  Go to Step 2.
NO:  Set "WING MIRROR" to "SPEED SEN FUN" by using the adjustment function.(Refer to .)
Step 2. Confirm communication data by using the SWS monitor.
Check the SWS communication signal, which are related to the electric retractable remote controlled door mirror vehicle speed-dependent unfolding function.

 ON

OK: Normal condition is displayed.
Q: Is the check result normal?
YES:  Go to Step 3.
NO:  Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received ."
Step 3. Check the ETACS ANAL data by using the SWS monitor.
Check the ETACS-ECU signal, which is related to the electric retractable remote controlled door mirror vehicle speed-dependent unfolding function.
  • Set the simulated vehicle speed at approximately 10km/h.
Item No.

 Normal conditions
Item 03
 SPEED SENSOR
 8 to 10km/h

OK: Normal condition is displayed.
Q: Is the check result normal?
YES:  Go to Step 4.
NO:  Refer to inspection procedure P-15 "The vehicle speed signal is not received ."
Step 4. Retest the system.
Check that the vehicle speed-dependent unfolding function works normally.
Q: Is the check result normal?
YES:  The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
NO:  Replace the ETACS-ECU.
