g. If the current is not within the specified range, check continuity of the wire
between the air inlet heater and engine ground. Check the connections at the
air inlet heater and at engine ground for corrosion.
(1) If the wire between the air inlet heater and engine ground is OK, replace
the air inlet heater (WP 0103).
(2) Verify that the problem is resolved.
MALFUNCTION
617-E-06 code. Current is below normal or circuit is open.
CORRECTIVE ACTION
STEP 1.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Connect the Cat ET to connector CDC-P7 (WP 0012).
STEP 3.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP set ENGINE CONTROL switch to COOL DOWN/STOP.
STEP 4.
Start the Air Inlet Heater Override on the Cat ET. Look for diagnostic code
617-E-06. Code 617-E-06 indicates the ECM detects a short circuit between the
air inlet heater relay and the ECM.
CAUTION
Do not leave the Air Inlet Heater Override ON. Avoid unnecessary cycling of the air inlet heater in
order to prevent the battery from discharging. The Air Inlet Heater Override has a one minute
timer that disables the test when the time expires.
STEP 5.
Stop the Air Inlet Heater Override.
STEP 6.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 7.
Check for a short circuit in the air inlet heater relay control circuit.
a. Disconnect connector ENG-P101 from ENG-J101 for the air inlet heater relay
control circuit.
b. Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to
NORMAL. On EMCP set ENGINE CONTROL switch to COOL
DOWN/STOP.
c.
Start the Air Inlet Heater Override on the Cat ET.
d. Verify the short circuit diagnostic code 617-E-06 changed to an open circuit
diagnostic code 617-E-05 when the control wires to the air inlet heater relay
were disconnected.
