Circuit/System Testing
Note: An intermittent or momentary, less than 1 s, loss of system voltage during throttle tip-in may set DTC P060D.
1. Ignition ON, clear the DTC information with a scan tool. Observe the scan tool DTC information. Verify that DTCs P0602 or P2610 do not
fail this ignition cycle.
瀚慖f DTC P0602 failed this ignition, reprogram the ECM. Refer to Control Module References (See: Testing and Inspection/Programming
and Relearning). If DTC P0602 resets, replace the ECM.
瀚慖f DTC P2610 failed this ignition, test the ECM ignition, battery positive voltage, and ground circuits for an open/high resistance or a
short to ground. If the circuits test normal, replace the ECM.
2. Ignition ON, observe the DTC information with a scan tool. Verify DTCs P0601, P0603, P0604, P0606, P0607, P060D, P062F, or P16F3 do
not set this ignition cycle.
瀚慖f any of the DTCs set this ignition cycle, replace the ECM.
