[54C] SMART WIRING SYSTEM (SWS) 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. Check the adjustment function. Check that "WING MIRROR" is set to "SPEED SEN FUN" by using the adjustment function. Q: Is the check result normal? YES: Go to Step 2. NO: Set "WING MIRROR" to "SPEED SEN FUN" by using the adjustment function.(Refer to .)
| Step 2. Confirm communication data by using the SWS monitor. Check the SWS communication signal, which are related to the electric retractable remote controlled door mirror vehicle speed-dependent unfolding function. <Selected item> ETACS ECU Ignition switch: IG1
Item No. | Item name | Normal conditions
--- | --- | ---
Item 30 | IG SW (IG1) | ON
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received ."
| Step 3. Check the ETACS ANAL data by using the SWS monitor. Check the ETACS-ECU signal, which is related to the electric retractable remote controlled door mirror vehicle speed-dependent unfolding function. Set the simulated vehicle speed at approximately 10km/h.
Item No. | Item name | Normal conditions
--- | --- | ---
Item 03 | SPEED SENSOR | 8 to 10km/h
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 4. NO: Refer to inspection procedure P-15 "The vehicle speed signal is not received ."
| Step 4. Retest the system. Check that the vehicle speed-dependent unfolding function 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 ETACS-ECU.
