[54B] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-13: All the door switch signals are not received. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-13: All the door switch signals are not received.
| 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. Door-ajar warning function Keyless entry system Dome lamps Security alarm
| 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 conditions
--- | ---
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" .
| Step 2. Connector check: D-42 <front, RH>, D-28 <front, LH>, 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 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-42 <front, RH>, D-28 <front, LH>, D-10 <rear, RH> or D-20 <rear, LH> door switch connectors 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-117 <LH> and junction block connector C-205 <LH> or C-221 <RH 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.
