INSPECTION PROCEDURE 3: The ABS Warning Lamp Remains Illuminated after the Engine is Started.
NOTE: This diagnosis procedure is limited to cases where communication with the MUT-II/III is possible (ABS-ECU power supply is normal) and no diagnosis code outputs.
CIRCUIT OPERATION Refer to .
TECHNICAL DESCRIPTION (COMMENT) Disconnected ABS warning lamp output line of ABS-ECU is suspected.
TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CONDITION:) Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with ABS-ECU) Malfunction of the combination meter
| DIAGNOSIS
| STEP 1. Check the ABS warning lamp circuit at ABS-ECU connector B-03. Disconnect ABS-ECU connector B-03. Connect ABS-ECU connector B-03 terminal number 12 to earth. Turn the ignition switch to the "ON" position. Q: Does the ABS warning lamp go off? YES: To check and reproduce the state of malfunction replace the hydraulic unit (integrated with ABS-ECU). Then go to Step 3. If the malfunction is not reproduced, an intermittent malfunction is suspected. NO: Go to Step 2.
| STEP 2. Check the harness wire between the combination meter connector C-05 terminal 18 and ABS-ECU connector B-03 terminal 12. NOTE: After inspecting combination meter connector C-105, inspect the wire. If combination meter connector C-105 is damaged, repair or replace it. Then go to Step 3. Q: Is the harness wire between combination meter connector C-05 terminal 18 and ABS-ECU connector B-03 terminal 12 damaged? YES: Replace the combination meter (printed circuit board) and then go to Step 3. NO: Repair the harness wire and then go to Step 3.
| STEP 3. Retest the system. Q: Does the ABS warning lamp turn off in 3 seconds after start-up? YES: The procedure is complete. NO: Return to Step 1.
