[54B] SMART WIRING SYSTEM (SWS) NOT 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. Pulse check
Check the input signals below which are related to the electric retractable remote controlled door mirror vehicle speed-dependent unfolding function.
System switch
 Check conditions
Ignition switch (IG1)
 When turned from ACC to ON
Vehicle speed signal (engine-A/T-ECU)
 When the vehicle speed has reached 10 km/h or more

OK: The MUT-II/III sounds or the voltmeter needle fluctuates.
Q: Are the check result normal?
All the signals are received normally.:  Go to Step 2.
The ignition switch (IG1) signal is not received.:  Refer to inspection procedure P-2 "The ignition switch (IG1) signal is not received ."
The vehicle speed signal (engine-A/T-ECU) is not received.:  Refer to inspection procedure P-15 "The vehicle speed signal is not received ."
Step 2. Check the SWS monitor customized function.
Use the SWS monitor customize function to confirm that "WING MIRROR" is set to "SPEED SEN FUN".
 CAUTION
 The SWS monitor must be used in order to confirm and change that setting. Use the SWS monitor to confirm and/or change the customized function.
Q: Is the check result normal?
YES:  Go to Step 3.
NO:  Use the SWS monitor customize function to set the "WING MIRROR" to "SPEED SEN FUN" (Refer to GROUP 54C - Adjustment function ).
Step 3. Retest the system.
The vehicle speed-dependent unfolding function should now work 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.
