Troubleshooting
If the fault is declared present, refer to "Cruise Control System Symptom Diagnosis in Section 10A".
Check that by pressing the buttons the statuses change and that with ignition switched on, all the values are
correct.
If the fault is still present, substitute a known-good ECM and recheck.

DTC P0606: ECM Processor

NOTE
• DTC P0606 D6 (current) will be detected rarely even if system is in normal condition when
connecting battery with IG ON and it can't be cleared using normal procedure described in "DTC
Clearance: For Diesel Engine Model".
In this case, clear DTC P0606 D6 as follows.
a. Connect SUZUKI scan tool to DLC with IG switch OFF.
b. Turn IG switch to ON position.
c. Select "Clear DTC (current P0606 D6)" under "Trouble Code" mode of SUZUKI scan tool and
follow instructions displayed on SUZUKI scan tool.
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after an attempted start, or with the engine running.
• If D6, D8 or D12 is present, the Injection warning light (gravity 1 warning light) is lit.
• If one of the other faults is present, the Red stop warning light (gravity 2 warning light) is lit.
• If D6 is still present, the Malfunction indicator light (MIL) will come on after three consecutive driving
cycles (starting +5 seconds + turn OFF ignition switch and wait 40 seconds.).
• Use service wire for all operations on the ECM connectors.
• Priority when dealing with a number of faults:
Deal with fault "DTC P0560: System Voltage: For Diesel Engine Model" first if it is present or stored.
