Replacement Of The Relay ModuleThe Rear View of the PRCM (1) Relay Module (2) Screws (3) Tape (4) Desiccant Package (5) O-Ring Seal (6) Cable connectorRelay module (1) contains the relays, fuses and terminals that are used to operate external devices of the PRCM system. Relay module (1) is a component of the PRCM.Reference: Special Instruction, SEHS9710, "Relay Module Replacement".Replacement Procedure
Remove the positive lead wire from the battery.
Make sure that all wires at the terminal strips of the relay module (1) are marked. During reassembly, the wires that are marked must be reattached to the correct terminals. Remove all wires from the terminals and posts of relay module (1) .
Remove ten screws (2) that fasten relay module (1) to the PRCM.
Be aware that O-ring seal (5) exists. Partially separate relay module (1) from the PRCM. Carefully disconnect cable clamp and cable connector (6) from relay module (1) .
Replace desiccant package (4) with the new desiccant package and tape that is included with the replacement relay module. The new desiccant package is attached in the same manner as the previous desiccant package.Note: Remove the new desiccant package from the protective container just prior to installation into the PRCM. The replacement of the relay module is approximately a 20 minute procedure. The desiccant package will become saturated with moisture particularly if the relay module is disassembled for more than 20 minutes. In a humid environment, the desiccant package becomes saturated sooner.
Install new O-ring seal (5) in the groove of relay module (1). Make sure that O-ring seal (5) is seated properly. Align and reconnect cable connector (6) to the relay module (1). Install the cable clamp.
Place relay module (1) on the PRCM. Check that O-ring (5) remains seated. Align the screw holes of relay module (1) and the PRCM. Install the ten screws and tighten the ten screws (2) to 1.70 0.25 N m (15 2 lb in).
Reconnect all the wires to the terminals of the relay module that were removed. Reconnect the positive lead wire to the battery.
