VALVE RELAY DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK INPUT VOLTAGE OF ABSCM&H/U. Turn the ignition switch to OFF. Disconnect the ABSCM&H/U connectors. Run the engine at idle. Measure the voltage between ABSCM&H/U connector and chassis ground. Connector & terminal (B301) No. 18 (+) - Chassis ground (-): (b301) No. 14 (+) - Chassis ground (-):	Is the voltage 10 - 15 V?	Go to step 2.	Repair the harness connector between battery and ABSCM&H/U.
2 CHECK THE ABSCM&H/U GROUND CIRCUIT. Turn the ignition switch to OFF. Measure the resistance between the ABSCM&H/U connector and chassis ground. Connector & terminal (B301) No. 15 - Chassis ground:	Is the resistance less than 0.5 Ω?	Go to step 3.	Repair the ABSCM&H/U ground harness.
3 CHECK VALVE RELAY IN ABSCM&H/U. Measure the resistance between the ABSCM&H/U terminals. Terminals No. 14 - No. 15:	Is the resistance 1 MΩ or more?	Go to step 4.	Replace the ABSCM only. <Ref. to REPLACEMENT , ABS Control Module and Hydraulic Control Unit (ABSCM&H/U).>
4 CHECK POOR CONTACT IN CONNECTOR.	Is there poor contact in connector between generator, battery and ABSCM&H/U?	Repair the connector.	Go to step 5.
5 CHECK ABSCM&H/U. Connect all connectors. Erase the memory. Perform the Inspection Mode. Read the DTC.	Is the same DTC displayed?	Replace the ABSCM only. <Ref. to REPLACEMENT , ABS Control Module and Hydraulic Control Unit (ABSCM&H/U).>	Go to step 6.
6 CHECK FOR ANY OTHER DTC ON DISPLAY.	Is any other DTC displayed?	Check DTC using "List of Diagnostic Trouble Code (DTC)". <Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . >	Temporary poor contact occurs.
