Please discard PIT5391E. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition / Concern Some owners may comment of any of the following symptoms: - No crank or a start then immediate stall - SES MIL may not be on when the ignition is in the Run position - On Diesel Models the Wait To Start light is inoperative - Any of the following DTC's may be set: B048D, B1370, B1325, P0381, P0650, P263A, P263B, P0513, P129D, P2535, and/or P0262B - Trucks equipped with 4WD may have a Service 4WD message and DTC's C0364 and/or U0403 may set - The sound of a relay clicking while driving - Rearview camera inoperative when the vehicle is shifted into reverse - Heated Steering Wheel Inoperative - Engine stays running with ignition off until door is opened (NOTE: This symptom is not caused by a loss of ignition 1 voltage, but a loss of ground to the Ignition Main Relay) These concerns could be caused by a loss of ignition 1 voltage. There are two KR73 Ignition Main Relays, one located in the Underhood Fuse Block-X50A, and the other in the Left I/P Fuse Block-X51L, that both provide power to several different fuses: Below are ONLY example wiring diagrams for the KR73 Ignition Main Relays and fuses. Use SI to look up your specific wiring diagram: Pickup's - Document ID: 3619755 SUV's - Document ID: 4079484 The loss of ignition 1 voltage may be caused by: -Either or both KR73 Ignition Main Relays not turning on to provide power to their respectable fuses. -Terminal issues at a fuse block connector where the Ignition 1 circuits exit the fuse block, example Document ID: 4232460, circuit 439 at the Underhood Fuse Block connector X2 terminal M7. In these situations, the KR73 Ignition Main Relays are turning on and providing power to their respective Ignition 1 fuses, but there will be no Ignition 1 power to their respective module/component, due to the terminal issue at the fuse block. Recommendations / Instructions The following are common areas for these concerns: 1. Inspect ALL the Underhood Fuse Block-X50A connectors for any backed out terminals, poor terminal fit and/or bent/twisted terminals. The most common terminals with these issues have been: -Terminal M5 at connector X4, for circuit 5199 -Terminal M7, A2 or A3 at connector X2 for circuit 439 (Depending on model and year, circuit 439 can vary in terminal location. Refer to SI for your vehicle) 2. Inspect for any backed out terminals, poor terminal fit and/or bent/twisted terminals at the Left I/P Fuse Block-X51L. The most common terminals with these issues have been: -Terminal 42 at connector X1, for circuit 5199 -Terminal 44 at connector X2, for circuit 1850 3. Circuit 5199 under the driver's sill plate for being damaged/corroded, as shown below. Repair any wiring / terminal issues using the appropriate SI wiring repair documentation. Warranty Information Please refer to latest version of bulletin 10-00-89-005 for warranty information on wire/connector repairs.
