How to troubleshoot Series 60 DDEC VI troubleshooting?
Install breakout box J-48475 and use cables J-48583. Measure the resistance between pins 44 and 45 of the MCM 120 pin connector. If the resistance is less 140 Ω, go to step 4 . If the resistance is greater than 140 Ω, go to step 6 . Disconnect the CMP Sensor. Measure the resistance between pins 44 and 45 on the breakout box.
Are there any problems with Detroit Diesel Series 60 engines?
Changing the SRS (Synchronous Reference Sensor) and TRS (Timing Reference Sensor) could also help with this issue. These two sensors should be replaced at the same time to maintain proper operation. This particular issue affects Series 60 engines built before 2002.

How many valves are in a series 60g engine?
Cylinder Head Assembly (Series 60G Engine) The porting within the cylinder head is cross-flow, with intake and exhaust ports on opposite sides for minimum restriction and maximum exposure to coolant flow. Four valves are used per cylinder, two intake and two exhaust. See Figure “Intake and Exhaust Valve Porting” . Figure 4.
Are there any problems with the Detroit Series 60?
This issue did not affect all pre-2002 Series 60 engines, but it was a problem that occurred and could cause catastrophic engine failure. As with most engines, it’s a good idea to keep an eye on your cooling system. Overheating is the cause of many major issues with diesel engines, so maintaining this system can help with many preventable issues.
How does the SRS warning system work in a car?
