Diagnostic Codes Table    
Code and Description     Conditions which Generate this Code     System Response    
617-5 Inlet Air Heater Relay : Current Below Normal     The Electronic Control Module (ECM) detects a current flow that is below normal during an attempt to energize the air inlet heater relay.     The code is latched. The code is logged.
The air inlet heater will be disabled if an open has occurred in the wiring in the circuit. The air inlet heater will be energized continuously if a short to the +Battery has occurred in the wiring in the circuit.    
617-6 Inlet Air Heater Relay : Current Above Normal     The ECM detects excessive current during an attempt to energize the air inlet heater relay.     The code is latched. The code is logged.
The air inlet heater will be disabled.
The engine may experience hard starting and/or the engine may emit excessive white smoke.    Use the following information in order to check the operation of the air inlet heater and the air inlet heater relay.The following background information is related to the operation of the air inlet heater:The air inlet heater is used to improve the ability of the engine to start when the engine is cold. A reduction of white smoke and reduced emission levels are also benefits of the air inlet heater.The ECM controls the operation of the air inlet heater and the ECM controls the operation of the lamp for the air inlet heater. The same technique for troubleshooting the primary circuit of the relay can be utilized for the lamp circuit.Interaction of the Air Inlet Heater and the Starting Aid Output (Ether)When the keyswitch is turned to the ON position, the air inlet heater will not be activated if the output of the starting aid is programmed to "Automatic", and if the inlet air temperature is below 0 °C (32 °F). The air inlet heater will not be activated when the starting aid circuit is activated. When the output of the starting aid is programmed to "Automatic", the air inlet heater will not be activated until the engine is running and the starting aid output has been turned off for five seconds.Effects of Vehicle Speed on the Operation of the Air Inlet Heater and on the Operation of the Brake Pedal PositionThe air inlet heater is turned off when the brake pedal is depressed and the vehicle speed is equal to 8 km/h (5 mph) or greater than 8 km/h (5 mph).If a diagnostic code for the vehicle speed sensor is active, the ECM will assume that the vehicle speed is above 8 km/h (5 mph). If an active diagnostic code is triggered for the vehicle speed sensor, the ECM will disable the heater when the brakes are applied.The system has three modes of operation:
Mode of powerup and preheat
Mode of engine cranking
Mode of engine started.Mode of Powerup and PreheatRegardless of temperature, the heater and the lamp for the heater will be activated for two seconds when the ECM is first powered (lamp check).The ECM then calculates the sum of the coolant temperature plus the
