Preparation: Remove the ABS SOL relay from engine room R/B No. 8.

Check: Measure the voltage between terminals 1 and 2 of engine room R/B No. 8 (for ABS SOL relay).

OK: Voltage: 10-14 V.

NG: Check and repair harness or connector.

If OK , go to step 2.
Check ABS SOL relay.
Check: continuity between following terminals of ABS SOL relay.

NG: Replace ABS SOL relay.

If OK , go to step 3.
Check continuity between terminal 3 of engine room R/B No. 8 (for ABS SOL relay) and each solenoid terminal of ABS & BA & TRAC & VSC ECU.
Preparation: Disconnect the connector from the ABS & BA & TRAC & VSC ECU.

Check: continuity between terminal 3 of engine room R/B No. 8 and each terminal, 3, 4, 5, 6, 25, 26, 49, 50, 52, 53, 54 and 55 of ECU harness side connector.

OK: Continuity.

NOTE:
Resistance of each solenoid coil.

SFLH (5), SRRH (6), SFRH (26), SMC1 (49), SMC2 (50), SRLH (53): 8-9.1 ohms

SFLR (3), SRRR (4), SRLR (25), SRC2 (52), SRC1 (54), SFRR (55): 4.0-4.6 ohms

NG: Repair or replace harness or brake actuator.

If OK , go to step 4.
Check for open and short circuit in harness and connector between ABS SOL relay and ABS & BA & TRAC & VSC ECU . See HOW TO USE THE DIAGNOSTIC CHART AND INSPECTION PROCEDURE .

NG: Repair or replace harness or connector.

OK: If the same code is still output after the DTC is deleted, check the contact condition of each connection. If the connections are normal, the ECU may be defective.
