[54E] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Except for Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-16: The vehicle speed signal is not received. <Except vehicles for GCC> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-16: The vehicle speed signal is not received. <Except vehicles for GCC>
| CAUTION Whenever the ECU is replaced, ensure that the input signal circuit is normal.
| COMMENTS ON TROUBLE SYMPTOM The vehicle speed signal is used to operate the Windshield wiper and washer (vehicle speed-dependent wiper function). If the signal is abnormal, the function will not work normally.
| POSSIBLE CAUSES Malfunction of the engine-A/T-ECU Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check if the A/T related diagnosis code is set. Q: Is the diagnosis code set? YES: Diagnose the automatic transmission control system. (Refer to GROUP 23 - Troubleshooting ) NO: Go to Step 2.
| Step 2. Connector check: C-110 engine-A/T-ECU connector and C-219 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 3. NO: Repair the defective connector.
| Step 3. Check the wiring harness between C-110 engine-A/T-ECU connector terminal No.80 and C-219 ETACS-ECU connector terminal No.63. NOTE: Prior to the wiring harness inspection, check joint connector C-02 <LH drive vehicles> and intermediate connector C-105, and repair if necessary. Check the input line for open circuit. Q: Is the check result normal? YES: Go to Step 4. NO: Repair the wiring harness.
| Step 4. Check the speedometer. Check that the speedometer works normally. Q: Is the check result normal? YES: Go to Step 5. NO: Replace the engine-A/T-ECU.
| Step 5. Pulse check Check the vehicle speed signal.
