continue to the next step.
i.
If all continuity measurements are good and the problem has not been
resolved, replace the ether solenoid (WP 0073). Verify the problem has
been resolved. If not, continue to the next step.
STEP 6.
Disconnect ENG-P213 from the ether relay (FO-2 Sheet 2).
a. Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to
NORMAL. On EMCP set ENGINE CONTROL switch to COOL
DOWN/STOP.
b. Proceed to the Diagnostic Overrides screen on the Cat ET.
c.
Activate the Ether Injection System. The diagnostic override will activate for
ten seconds.
d. Monitor the Active Diagnostic Codes screen on the Cat ET.
e. Check for an active 05 diagnostic code for the ether circuit.
STEP 7.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
a. Connect a jumper wire between ENG-P213-1 and ENG-P213-2.
b. Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to
NORMAL. On EMCP set ENGINE CONTROL switch to COOL

f.
Check for an active 06 diagnostic code for the ether circuit.
g. On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF. Remove
the wire jumper.
(1) If a 06 diagnostic code was active when the jumper wire is installed and
a 05 diagnostic code was active when the jumper wire is removed, the
engine harness and the ECM are OK.
(2) If the diagnostic codes do not change as stated above, verify continuity
between ENG-P213-1 and ENG-P1-21. Repair as necessary
ether relay (WP 0073).
(3) Verify the problem has been resolved. If not, replace the ECM
