DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK 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) . >	Go to step 2 .
2 CHECK HARNESS BETWEEN ECM AND EGR VALVE CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from EGR valve. Turn the ignition switch to ON. Measure the voltage between ECM connector and chassis ground. Connector & terminal DTC P1493; (B134) No. 8 (+) - Chassis ground (-): DTC P1495; (B134) No. 9 (+) - Chassis ground (-): DTC P1497; (B134) No. 10 (+) - Chassis ground (-): DTC P1499; (B134) No. 20 (+) - Chassis ground (-):	Is the voltage more than 10 V?	Repair the battery short in harness between ECM and EGR valve connector. After repair, replace the ECM. < Ref. to ENGINE CONTROL MODULE (ECM) . >	Replace the ECM. < Ref. to ENGINE CONTROL MODULE (ECM) . >
