Ignition switch: OFF Operate the multimode function with the keyless entry transmitter. ECUS TO BE CHECKED ETACS ECU P/W MODULE OK: "OK" are displayed for all the items Q: Is the check result normal? "OK" are displayed for all the items: Go to Step 5. "NG" is displayed on the "ETACS ECU" menu.: Refer to Inspection Procedure A-3 "Communication with the ETACS-ECU is not possible ." "NG" is displayed on the "P/W MODULE" menu.: Refer to Inspection Procedure A-5 "Communication with the power window main switch (power window module) is not possible ."
| Step 5. Use the SWS monitor to examine the keyless entry system for signal reception. Check the condition of the keyless entry transmitter.
Operation switch | Normal conditions (received signal)
--- | ---
LOCK (1 second or more) | LOCK
LCK LNG PUSH
UNLOCK (1 second or more) | UNLOCK
ULCK LNG PUSH
| OK: By operating the switch as shown in the table above, relevant normal conditions are displayed. Q: Is the check result normal? YES: Go to Step 6. NO: Refer to inspection procedure P-16 "Each switch signal of the keyless entry transmitter is not received ."
| Step 6. Confirm communication data by using the SWS monitor. <Selected item> ETACS Ignition switch: OFF Operate the multimode function with the keyless entry transmitter.
Item No. | Item name | Normal conditions
--- | --- | ---
Item 30 | IGNITION SW IG1 | OFF
Item 34 | KEYLESS ENTRY | MULTI CLOSE, MULTI OPEN or MULTI STOP
OK: Normal conditions displayed for all the items Q: Are the check result normal? Normal conditions are displayed for all the items.: Go to Step 7. Normal condition is not displayed for item No.30: Refer to inspection procedure P-2 "The ignition switch (IG1) signal is not received ." Normal condition is not displayed for item No.34: Replace the ETACS-ECU.
| Step 7. Retest the system. Check that the multimode keyless entry system 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 power window main switch.
