B211F
B211F-IGNITION RUN/ACC/PAD CONTROL CIRCUIT HIGHB211F-Ignition Run/Acc/Pad Control Circuit High:
WHEN MONITORED
With the ignition on.
SET CONDITION
The Front Control Module will set this DTC within 500ms if the (P307) Ignition Run/Acc/Pad Relay Control circuit is shorted to voltage.
POSSIBLE CAUSES
- (P307) accessory delay relay control circuit shorted to voltage
- Accessory delay relay
- Front control module
DIAGNOSTIC TEST
1. CHECK FOR ACTIVE DTC
With the scan tool, read the active DTC's.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active DTC's.
Q: Does the scan tool display this DTC as active?
YES: Go To 2
NO: If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
2. ACCESSORY DELAY RELAY
Turn the ignition off.
Install a substitute relay in place of the original Accessory Delay Relay.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
With the scan tool, read the active FCM DTC's.
Q: Does the scan tool display this DTC as active?
YES: Go To 3
NO: Replace the original relay. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
3. (P307) ACCESSORY DELAY RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE
Turn the ignition off.
Remove the FCM from the Power Distribution Module.
Remove the Accessory Delay Relay from the Rear Power Distribution Module.
Turn the ignition on.
Measure the voltage of the (P307) Accessory Delay Relay Control circuit at the relay connector (cavity 85).
Q: Is there any voltage present?
YES: Repair the (P307) Accessory Delay Relay Control circuit for a short to voltage. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Inspect the wiring and connectors for damage or shorted circuits. If OK, replace and program the Front Control Module. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
