FLASHER TIMER

INSPECTION PROCEDURE M-1: The turn-signal lamps do not illuminate.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If all the turn-signal lamps do not illuminate, the ignition switch (IG1), the turn-signal lamp switch input circuit or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the column switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check that the hazard warning lamps operate. Check that the hazard warning lamps illuminate normally. Q: Is the check result normal? YES: Go to Step 6. NO: Go to Step 2.
| Step 2. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 3. NO: Repair the defective connector.
| Step 3. Measure the voltage at the C-217 ETACS-ECU connector. Remove the ETACS-ECU, and measure at the junction block side. Voltage between C-217 ETACS-ECU connector terminal No.11 and body earth OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 5. NO: Go to Step 4.
| Step 4. Check the wiring harness between C-217 ETACS-ECU connector terminal No.11 and the battery. NOTE: Prior to the wiring harness inspection, check intermediate connector C-116 and junction block connector C-202, 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 5. Retest the system. Check that the turn-signal lamps illuminate 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.
| Step 6. Function diagnosis by using the SWS monitor Check the SWS communication signal, which are related to the right turn-signal lamps. <Selected item> TURN SIGNAL - TURN-SIG. RH Turn-signal lamp switch: RH Ignition switch: ON
Item No. | Item name | Normal condition
--- | --- | ---
Item 10 | TURN SIG.RH | ON
Item 11 | TURN SIG.LH | OFF
Item 30 | IG SW(IG1) | ON
OK: Normal conditions displayed for all the items Q: Is the check result normal? Normal conditions are displayed for all the items.: Go to Step 7. Normal condition is not displayed for item 10 or 11.: Refer to Inspection Procedure P-5 "The column switch (lighting and turn-signal lamp switch) signal is not received ." Normal condition is not displayed for item No.30.: Refer to Inspection Procedure P-2 "The ignition switch (IG1) signal is not received ."
| Step 7. Function diagnosis by using the SWS monitor Check the SWS communication signal, which are related to the left turn-signal lamps. <Selected item> TURN SIGNAL - TURN-SIG. LH Turn-signal lamp switch: LH Ignition switch: ON
Item No. | Item name | Normal condition
--- | --- | ---
Item 10 | TURN SIG.RH | OFF
Item 11 | TURN SIG.LH | ON
OK: Normal condition is displayed. Q: Is the check result normal? Normal conditions are displayed for all the items.: Go to Step 8. Normal condition is not displayed for item 10 or 11.: Refer to Inspection Procedure P-5 "The column switch (lighting and turn-signal lamp switch) signal is not received ."
| Step 8. Retest the system. Check that the turn-signal lamps illuminate. 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.
