Is any voltage indicated?
Yes
REPAIR circuit 599 (PK/LG) and/or 77 (DB/Y). CLEAR the DTCs. TEST the system for normal operation.
No
REPLACE the GEM; REFER to
Section 419-10
. CLEAR the DTCs. TEST the system for normal operation.
E20
CHECK THE PVH SOLENOID FOR PROPER VACUUM OUTPUT LEVEL — 4X4 ENGAGED
PVH Solenoid C185
Connect a vacuum gauge to the PVH vacuum line tee fitting and measure the vacuum while switching the 4X4
mode switch to 4X4 HIGH.
Does the vacuum gauge indicate at least 11 in/Hg after six seconds but not longer than 60 seconds
after switching the 4X4 mode switch to 4X4 HIGH?
Yes
GO to
E21
.
No
REPLACE the PVH solenoid; REFER to
Section 204-01B
. TEST the system for normal operation.
E21
CHECK THE PVH SOLENOID FOR PROPER VACUUM OUTPUT LEVELS — 4X4 DISENGAGED
NOTE:
This step requires the use of a calibrated vacuum gauge that is accurate to within a minimum of 0.1 in/Hg. It is recommended that Pressure/Vacuum Module or equivalent
105-R0099 be used for this check.
Observe the vacuum gauge while switching the 4X4 mode switch to 2WD.
Does the vacuum gauge indicate between 5.85 and 7.1 in/Hg after six seconds but not longer than 60
seconds after switching the 4X4 mode switch to 2WD?
Yes
REMOVE the vacuum gauge. RECONNECT all vacuum lines. TEST the system for normal operation. If the 4X4
system still does not operate properly, CLARIFY the customer concern and RETURN to Symptom Chart.
No
REPLACE the PVH solenoid; REFER to
Section 204-01B
. TEST the system for normal operation.
E22
CHECK THE RH SIDE WHEEL END FOR LEAKS
Disconnect the RH wheel end vacuum line connector.
NOTE:
This step may require rapid pumping for up to 10 seconds.
Connect a hand vacuum pump to the RH wheel end vacuum line connector and try to pull a vacuum to 15
in/Hg.
Does the vacuum drop exceed 0.5 in/Hg in 30 seconds?
