3 CHECK GROUND SHORT OF HARNESS. Turn the ignition OFF. Disconnect the connector (B301) from the ABSCM&H/U. Disconnect the connector (i10) from combination meter. Measure the resistance between ABSCM connector and chassis ground. Connector & terminal (B301) No. 22 - Chassis ground:	Is the resistance more than 1 MΩ?	Go to step 4.	Repair harness and connector between ABSCM&H/U and combination meter.
4 CHECK ABSCM. Connect the connector (B301) to the ABSCM&H/U. Turn the ignition ON. Measure the resistance between the combination meter connector and chassis ground soon after the ignition switch is turned to ON (within 1.5 seconds).
