INPUT SIGNAL PROCEDURES

INSPECTION PROCEDURE P-1: The ignition switch (ACC) signal is not received.
| CAUTION Whenever the ECU is replaced, ensure that the input signal circuit is normal.
| COMMENTS ON TROUBLE SYMPTOM Input signal from the ignition switch (ACC) is used to operate the functions below. If the signal is abnormal, these functions will not work normally. Windshield wiper and washer Rear wiper and washer Electric-folding door mirror Interior lamp automatic shutdown function
| POSSIBLE CAUSES Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 2. NO: Repair the connector.
| Step 2. Measure the voltage at the C-217 ETACS-ECU connector. Remove the ETACS-ECU, and measure at the junction block side. Ignition switch: ACC position Voltage between C-217 ETACS-ECU connector terminal No.18 and body earth OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 4. NO: Go to Step 3.
| Step 3. Check the wiring harness between C-217 ETACS-ECU connector terminal No.18 and the ignition switch (ACC). NOTE: Prior to the wiring harness inspection, check junction block connector C-203, and repair if necessary. Check the power supply line for open circuit. 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: Repair the wiring harness.
| Step 4. Retest the system. Check that the ignition switch (ACC) 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.
