[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-14: The vehicle speed signal is not received. <Except vehicles for GCC> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-14: 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 functions below. If the signal is abnormal, these functions will not work normally. Windshield wiper and washer (vehicle speed-dependent wiper function)
| 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 <2400-4G64> or <2400-4G69>) 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. Retest the system. Check that the vehicle speed signal is 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.
