WARNING: To avoid serious personal injury, possible death, or damage to the engine or vehicle,
always disconnect main negative battery cable first. Always connect the main negative battery cable
last.
EGR Drive Module Connector Resistance Checks to Chassis Ground (Turn the ignition switch to OFF.
Disconnect chassis connector 9260
module. Use disconnected negative battery cable for ground test point.)
