1. CHECK FOR FUEL PUMP OPERATION AND FUEL LEAKS
(a) Check fuel pump operation.
(1) Connect the Techstream to the DLC3.
(2) Turn the engine switch on (IG) and turn the Techstream on.

(b) Using a voltmeter, measure the battery voltage.
Standard voltage:
11 to 14 V
(c) Disconnect the cable from the negative (-) battery terminal.
CAUTION:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected See: Testing and
