[54B] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Hong Kong spec.> - - SYMPTOM PROCEDURES - ELECTRIC RETRACTABLE REMOTE CONTROLLED DOOR MIRROR - INSPECTION PROCEDURE I-6: Keyless entry system-linked fold/unfold function does not work normally.PRINT PAGE / INDEX / PRIOR / NEXT
INSPECTION PROCEDURE I-6: Keyless entry system-linked fold/unfold 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 keyless entry transmitter input signals. If this function does not work normally, keyless entry transmitter input signal circuit or the ETACS-ECU may be defective. In addition, it is possible that the function except the keyless entry system-linked fold/unfold function has been set by using the adjustment function.
POSSIBLE CAUSES
  • Malfunction of the keyless entry transmitter
  • Malfunction of ETACS-ECU
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Pulse check
Check the input signals from the keyless entry system transmitter switches.
System switch
 Check conditions
Keyless entry system transmitter switches
 When the switch is turned from off to on

OK: The MUT-II/III sounds or the voltmeter needle fluctuates.
Q: Is the check result normal?
YES:  Go to Step 2.
NO:  Refer to inspection procedure P-16 "Each switch signal of the keyless entry transmitter 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 "KEYLESS LINK".
 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 "KEYLESS LINK" (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.
