BEARING-CONNECTING ROD 2627163 - Caterpillar

Illustration 1 g00566282
(1) Chassis Control Module. (2) Coolant Temperature Sensor.This fault code indicates the engine coolant temperature sensor has a higher than normal voltage and may be due to an open circuit or a short to positive voltage. This fault code will only occur after the engine has been running for twenty minutes.
Visually inspect Rear Main harness, Front Main harness and connectors (C002, C008 and C104) for damage or disconnected connectors. Expected Result: There is damaged parts or broken parts.
YES, repair damage or reconnect connectors as appropriate. Check fault codes. If fault code is not active, repair is complete.
NO, go to Step 2.
Check sensor for an open circuit between C104-A and C104-B (more than 100K ohms). Expected Result: There is an open in the circuit.
YES, replace coolant temperature sensor with a new sensor and recheck fault codes. If fault code is not active, repair is complete.
NO, go to Step 3.
Disconnect connectors C002. Check for open circuit in Front Main and Rear Main harnesses between connector C104-A and C002-2. Also check between C104-B and C002-8. Expected Result: There is an open in the circuit.
YES, go to Step 4.
NO, go to Step 6.
Disconnect connectors C002 and C008. Check for open circuit in Front Main harness between connector C104-A and C008-S. Also check between C104-B and C008-X. Expected Result: There is an open in the circuit.
YES, locate and repair open circuit in Front Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 5.
Check for open circuit in Rear Main harness between connector C008-S and C002-2. Also check between C008-X and C002-8. Expected Result: There is an open in the circuit.
YES, locate and repair open circuit in Rear Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 6.
Check Front Main harness for short circuit to positive voltage from connector C104-A and C104-B (positive volts present when key start switch is ON). Expected Result: There is a short in the circuit.
YES, locate and repair short circuit in Front Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 7.
Check Rear Main harness for short circuit to positive voltage from connector C008-S and C008-X or C002-2 and C002-8. Expected Result: There is a short in the circuit.
YES, locate and repair short circuit in Rear Main harness. Check fault code and if no longer active the repair is complete.
NO, go to Step 8.
Download latest control module software into all control modules. Expected Result: The fault code is active.
YES, go to Step 9.
NO, repair is complete. Calibrate transmission and three-point hitch.
Replace the Chassis Control Module (CCM).Expected Result: The fault code is active.
YES, install the original CCM and repeat this troubleshooting procedure.
NO, go to Step 10.
Install the original CCM. Expected Result: The fault code is active.
YES, original CCM was faulty. Replace original CCM with new CCM. If fault code is not active, repair is complete. Download latest control module software into all modules. Calibrate transmission
