Is the problem found?
 | ▶ Repair the trouble causing part and go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "Power Circuit Inspection". |
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damage of component.
Perform checking procedure as follows.
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
Check connecting condition of ECM and component connector : Check terminal separation, damage of locking device and connecting condition between terminal and wiring.
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. (After checking, reconnect the pin at correct position.)

IG key OFF.
Connect GDS with 'DATA LINK CONNECTOR'(DLC) and disconnect glow plug connector.
Check voltage between 'GLOW PLUG' terminal of GCU harness connector and chassis ground after starting at the condition of engine coolant temperature is lower than 80℃.(Or perform actuation test - "GLOW RELAY" with GDS.)
Specification : 10.5V~14.5V (Getting decrease)
Is the measured value within specification?
| ▶ Go to " Component Inspection" procedure. |
| ▶ If no voltage detected, repair open / short to ground between 'GLOW PLUG #' terminal of 'GLOW PLUG #' harness connector and 'GLOW PLUG #' terminal of 'GLOW CONTROL MODULE' harness connector, and go to "Verification of Vehicle Repair" procedure. ▶ If the voltage is higher than specification, repair short to battery between 'GLOW PLUG #' terminal of 'GLOW PLUG #' harness connector and 'GLOW PLUG #' terminal of 'GLOW CONTROL MODULE' harness connector, and go to "Verification of Vehicle Repair" procedure. |
