Event Code 719
Event Code 719
Excessive Current SVA2A Solenoid Coil Circuit.
Event logged if excessive current flows through driver
CA230-9.
Step 1: Remove wire from CA230-9. Key on truck and
attempt to use accessory 2, monitor event code.
• If: Event 719 is not the last event.
– Then short is in the wiring or solenoid. Coil re-
sistance should be approximately 39 ohms.
Reinstall wire and proceed to Step 2.
• If: Event 719 is still the last event.
– Then replace ACCESS 7.
Step 2: Remove positive wire from solenoid. Key on
truck and attempt to use accessory 2, monitor event
code.
• If: Event 719 is still the last event.
– Then short exists in wiring, check for shorts be-
tween negative and positive wire.
• If: Event 719 is not the last event code.
– Then short exists in solenoid, replace solenoid.
Coil resistance should be approximately 39
ohms.
Event Code 720
Excessive Current SVH Solenoid Coil Circuit.
Event logged if excessive current flows through driver
CA230-5.
Step 1: Remove wire from CA230-5. Key on truck and
attempt to raise, monitor event code.
• If: Event 720 is not the last event.
– Then short is in the wiring or solenoid. Coil re-
sistance should be approximately 39 ohms.
Reinstall wire and proceed to Step 2.
• If: Event 720 is still the last event.
– Then replace ACCESS 7.
Step 2: Remove positive wire from solenoid. Key on
truck and attempt to raise, monitor event code.
• If: Event 720 is still the last event.
– Then short exists in wiring, check for shorts be-
tween negative and positive wire.
• If: Event 720 is not the last event code.
– Then short exists in solenoid, replace solenoid.
Coil resistance should be approximately 39
ohms.
