[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-12: All the door switch signals are not received. <LH drive vehicles>PRINT PAGE / INDEX / PRIOR / NEXT
INSPECTION PROCEDURE P-12: All the door switch signals are not received. <LH drive vehicles>
 CAUTION
 Whenever the ECU is replaced, ensure that the input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
Input signals from all the door switches are used to operate the functions below. If the signal(s) are abnormal, these functions will not work normally.
  • Keyless entry system
  • Room lamps
POSSIBLE CAUSES
  • Malfunction of the door switches
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Pulse check
Check the input signal from the driver's door switch.
System switch
 Check condition
Driver's door switch
 When the driver's door is opened

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-4 "The driver's door switch signal is not received <LH drive vehicles>."
Step 2. Connector check: D-28 <front, LH>, D-42 <front, RH>, D-10 <rear, RH> or D-20 <rear, LH> door switch connectors or F-07 <tailgate> tailgate switch connector, and C-217 ETACS-ECU connector
Q: Is the check result normal?
YES:  Go to Step 3.
NO:  Repair the defective connector.
Step 3. Check the installation condition.
Check that the door switch is installed on the body correctly.
Q: Is the check result normal?
YES:  Go to Step 4.
NO:  Correct the installation condition.
Step 4. Check the door switch.
Refer to GROUP 42 - Door .
Q: Is the check result normal?
YES:  Go to Step 5.
NO:  Replace the door switch.
Step 5. Check the wiring harness from terminal No.2 of the D-28 <front, LH>, D-42 <front, RH>, D-10 <rear, RH> or D-20 <rear LH> door switch connector or terminal No.1 of the F-07 <tailgate> tailgate switch connector to terminal No.7 of the C-217 ETACS-ECU connector.
NOTE: Prior to the wiring harness inspection, check intermediate connector F-05 <tailgate> or C-13 <RH> and junction block connector C-205 <RH> or C-209 <LH and tailgate>, and repair if necessary.
  • Check the input line for open circuit.
Q: Is the check result normal?
YES:  Go to Step 6.
NO:  Repair the wiring harness between each of the door switches and the ETACS-ECU.
Step 6. Retest the system.
Check that all the driver's door switch signals are received 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.
