P0606

DTC P0606 PCM Internal Performance




Circuit Description
The input/output devices in the PCM include analog-to-digital converters, signal buffers, counters, and special drivers. The PCM Controls most components with electronic switches which complete a ground circuit when turned "ON". These switches are arranged in groups of 4 and 7, called either a surface-mounted quad driver module (QDM), which can independently Control up to 4 output terminals, or QDMs which can independently Control up to 7 outputs.

Conditions for Setting the DTC
- This code detects inconsistencies between Main CPU A/D converters and Watchdog CPU A/D converters.

Action Taken When the DTC Sets
- The PCM will not illuminate the malfunction indicator lamp (MIL).
- The PCM will store conditions which were present when the DTC was set in the Failure Records data only

Conditions for Clearing the MIL/DTC
- The PCM will turn the MIL "OFF" on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
- A history DTC P0606 will clear after 40 consecutive warm-up cycles have occurred without a fault.
- DTC P0606 can be cleared by using the Tech 2 "Clear Info" function or by disconnecting the PCM battery feed
