(P201) ADJUSTABLE PEDALS RELAY CONTROL CIRCUIT OPEN OR HIGH RESISTANCE (IPM) Connect a jumper wire between the (P201) Adjustable Pedals Relay Using a 12-volt test light connected to 12-volts, check the (P201) NOTE: The test light should be illuminated and bright. Compare NOTE: Remove the jumper wire before proceeding to the next test. Is the test light illuminated and bright? Yes >> Go To 5 No >> Replace the Integrated Power Module in accordance with the Service Information. Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 - 5. ADJUSTABLE PEDALS RELAY Reconnect all components. Turn the ignition on. With the scan tool, actuate the Adjustable Pedals Relay. Measure the voltage of the (P201) Adjustable Pedals Relay Control circuit at the Adjustable Pedals Relay connector NOTE: With the Relay actuated ON, the circuit voltage should be 0 volts. NOTE: With the Relay actuated OFF, the circuit voltage should be approximately 2.5 volts. Does the circuit voltage display as described during the actuation test? Yes >> Replace the Adjustable Pedals Relay in accordance with the Service Information. Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
