VE- 7.0.0 ISOLATE VERR

a) From debug screen 0, RECORD the valve numbers of the valves whose 'dots' are BLUE!
these valve circuits may be the problem!
b) Call debug screen 1. NOTE VERR's value for reference later. If VERR EVER reaches 255 return to
procedure number VE- 1.0.0
c) Watch VERR until if it increases above what was noted in part b OR for five (5) minutes whichever
comes first! TWO (2) possible scenarios:

solenoid and its wire harness.

1)
IF VERR does DOES NOT increase: The last valve unplugged OR its blue wire harness is the

2) IF VERR increases: Repeat procedure number
unplugged. If after all these valve(s) are unplugged AND if VERR is still increasing, THREE (3)
possible bad components, see the Component List below:
