-> No GO to Pinpoint Test G187746t19.
G187746t5 : CHECK HARNESS BETWEEN FPDB AND EGR FOR SHORT TO 1. Disconnect the EGR valve electrical connector PI 15. 2. CHECK the resistance between PI 15 pin 2 (GU) and ground. Is the resistance less than 10,000 Ohms? -> Yes REPAIR the circuit between the EGR valve and FPDB. INSTALL a new fuse. CLEAR DTC. To validate fix drive vehicle between 30 mph (48 kph) and 40 mph (64 kph). Allow vehicle to idle for 2 minutes.
-> No INSTALL a new fuse. CLEAR DTC. To validate fix drive vehicle between 30 mph (48 kph) and 40 mph (64 kph). Allow vehicle to idle for 2 minutes. G187746t6 : CHECK FOR BATTERY VOLTAGE AT FPDB 1. CHECK for voltage at FPDB electrical connector FH 32 pin 43 (GU). Is the voltage less than 10 volts? -> Yes REPAIR the circuit between FPDB electrical connector FH 32 pin 43 (GU) and FPDB relay 5.
-> No REPAIR the circuit between FPDB electrical connector FH 32 pin 43 (GU) and EGR valve electrical connector PI 15 pin 2 (GU). CLEAR DTC. To validate fix drive vehicle between 30 mph (48 kph) and 40 mph (64 kph). Allow vehicle to idle for 2 minutes. G187746t19 : CHECK FOR POWER SUPPLY TO EGR VALVE 1. Disconnect EGR valve electrical connector PI 15 2. MEASURE the voltage at PI 15 pin 5 (GU) Is the voltage less than 10 volts? -> Yes REPAIR the circuit between PI 15 pin 5 (GU) and splice PIS 15. CLEAR DTC. TEST the system for normal operation.
-> No INSTALL a new EGR valve. CLEAR DTC. To validate fix drive vehicle between 30 mph (48 kph) and 40 mph (64 kph). Allow vehicle to idle for 2 minutes. |
