A6: CHECK
THE EGR VALVE TO ECM
CIRCUITS FOR SHORT TO GROUND
Meas
ure the resistance between the following:
PI34, pin
04 (YU) and GROUND
PI34, pin
01 (YG) and GROUND
PI34, pin
06 (YN) and GROUND
PI34, pin
03 (YR) and GROUND

Are
any of the resistances less than 10,000 ohms?
Yes REPAIR the short circuit. For addi tional information, refer to the wiring diagrams. CLEAR the DTC.
TEST the system for normal operation.
No Contact dealer technical support for advice on possible ECM failure.
